Motor application cases for ELAN-drive products

Stators are the stationary part of an electric motor and provide a rotating magnetic field that drives the rotating armature. The core of the stator is built up of high-grade alloy steel laminations, which is wound with round or flat wire conductors into slots. Once the winding of a stator has been completed, the final stage of manufacture will be to bond the winding by using an impregnating or encapsulating process
Other benefits that can be derived from the Impregnation or Encapsulation process would be void filling in the slot or improved thermal flow as well as increases chemical resistance, environmental protection and mechanical wear and damage. In general, the process ensures:

  • Electrical insulation
  • Chemical protection
  • Mechanical protection

Processing Methods
The application method to apply the impregnation or the encapsulation resins are quite different.  However, the process should ensure the wound coils in the slots are fully saturated and void free. 
Impregnation ProcessThere are several processes by which the impregnation resins can be applied, the determination as to which method to use depends on the dimensions of the stator and the daily product quantity. A summary of various impregnation processes is listed in the table below:


* Vacuum Pressure Impregnation

Encapsulation Process
Many variations on a standard encapsulation process are available. In principle the stator is placed into a mold, then resin is poured over the winding head. After the resin has entered the wound coils in the slots following a gelation and curing process. The cure may be performed at ambient temperature or at elevated temperature in an oven. Applying vacuum during the process will result in an excellent, void free encapsulation.

Advantage/disadvantage of encapsulating vs. impregnation

Requirements for eMobility application
Electrical insulation materials for eMobility motors face conflicting requirements. The eMobility motor is required to deliver high torque for brief periods and low torque for long periods. It will be subjected to a variety of environmental conditions from both high and low ambient temperature conditions, be resistant to oils, water, and salt from winter streets. Long-term reliability is an absolute, the electrical insulation must be tough enough to withstand high temperatures and chemicals, but also possess some degree of flexibility to manage temperature shocks and mechanical stress applied to the motor windings due the torque the motor develops.

 ELANTAS offers an extensive portfolio of high-performance materials for stator impregnating or encapsulating which meets the main requirements as:

  • Very good chemical resistance
  • Temperature Shock Resistance
  • VOC-free product range
  • Product portfolio for all processing methods
  • High thermal conductive materials
  • Partial discharge resistance

ELANTAS's globally available product range, ELAN-drive widely used in eMobility application: 

Today, rotors used for e-motors in electric cars are designed as Wound Rotors or Permanent Magnet Rotor (PM) in particular when higher power density is required. Depending on the rotor type and selected processing technology different materials are essential.

ELANTAS offers for all type of rotors and processing technologies the best material to stabilize the rotor against extreme centrifugal forces. 

ELANTAS products has proven superior properties in EV motors as:

  • Bonding at high rotation speed
  • Thermal shock stability
  • Support thermal management
  • Chemical resistance to aggressive oils and cooling fluids

The below table gives an overview on most common applied processing technologies, products and main characteristics in the manufacturing of wound rotors for e-motors:

Permanent Magnet Motors

Instead of coils, permanent magnet motors use strong magnets for the rotor element to generate the magnetic field. Collectively, these magnets need to be tightly fixed to the rotor steel package or the rotor housing. Motor developers have come up with various designs of magnet arrangements. Some magnets are pushed into pockets in the steel package of the rotor and are fixed with low viscous adhesive that fills the pocket; other magnets are fixed to the outside of the rotor which obviously is different as to the required adhesive strength and viscosity during application. Mostly, the maximum operation temperature of Magnets shall not exceed 80°C. For special high-end use in automotive the rotors are tested until 150°C.

ELANTAS products offered for magnet fixation

Electric motors for eMobility applications require higher power and torque at limited constructed space and weight in a car. This can be achieved by increasing the copper fill factor in the slots of the stator. Hence, flat wires are applied in the latest development of motors, especially for premium cars. 

Hair-Pin Technology
While conventional round wires are wound into the slots; flat wires must be inserted into the stator by the i-Pin or Hair Pin technique and thereof require welding on one or both sides of the copper pins connections following by insulation of the welded pins. Various technologies can be applied for this purpose: 

  • Epoxy Powder coating,
  • Potting
  • Impregnation

ELANTAS hair-pin protection solutions save time and budget.

While Epoxy powder coating requires an additional process step, ELANTAS offers insulation materials which can be applied in one process step and with similar process equipment used today. Applying ELANTAS solutions further process benefits as reduced investment and faster process time can generated

ELANTAS has screened various electrical insulating materials for Hair Pin Protection and developed materials. During the extensive study (LINK) of materials in combination with the application technique ELANTAS developed materials with:

  • excellent edge coverage
  • excellent thermal shock resistance
  • oil compatibility
  • application by a conventional processing technique

As further requirement based on the motor design and operation condition needs to be considered, ELTANTAS offers our technical knowledge for individual technical consulting during the design, test and production phase.

The table below shows the most global applied ELAN-drive materials for Hair Pin Protection:

To create an electromagnetic field in an electric motor, a conductive coil where each conductor of the coils has an electrical insulation wire is required. For low and medium voltage machines, the electrical insulation otherwise known as primary insulation is created by laying down, in multiple passes, and enamel. The wire manufactured by this process is known as magnet wire.  It is a unique product as the magnet wire, which comes in round or rectangular (flat) shaped wire and offers the following features:

  • High dielectric properties
  • High temperature durability
  • Chemical resistance
  • Excellent mechanical properties

Processing Methods
Motor coils are generally produced by high-speed winding or insertion machines. It is a requirements of motor manufacturers to produce electric motors as quickly and efficiently as possible to minimize costs. Magnet wire must withstand the forces applied to it to ensure the coils are tightly wound and compact, the magnet wire is pulled or threaded into the slots which exerts extreme force on the magnet wire and the primary coating. Finally, there may be a forming process to the wound coils which applies mechanical force so the magnet wire to form the required shape.

Requirements for eMobility application
For the eMobility motor application, the magnet wires must exhibit excellent thermal, electrical and mechanical properties. The shape of the magnet wire will be either round or rectangular, this will depend on the motor design. With increasing demands on high-voltage, high-output and large capacity motors, rectangle or flat wires with a higher space factor are more and more used for eMobility application to increase motor performance. 

Round wire will need to be withstand high speed winding. The motors winding could also be subject to partial discharge. ELANTAS provides corona resistant protection such and special partial discharge resistant coatings. As the winding could be subject to high temperatures, coatings such as Polyamideimde and Polyimide are also available. ELANTAS offers both and even in combination with corona resistance properties.

For rectangular or flat wire ELANTAS has developed unique products covering variety of properties such as:

  • High conformity of coating (edge covering)
  • Layer thickness up to 150 µm
  • Corona resistance
  • High flexibility
  • Good adhesion to conductor and secondary insulation

ELANTAS offers an extensive portfolio of high-performance enamels for magnet wire to meet the conflicting requirements. With ELANTAS excellent primers and self-lubricated enamels, wire structures can be extended further, and the performance can be improved to even higher level.

ELANTAS’s globally available product range ELAN-drive widely used in eMobility application: 

 *To achieve the best properties of a final magnet wire a combination of wire enamels is applied. Covering polyester or polyamide enamels with polyamide-imide leads to outstanding adhesion, dielectric and thermal properties. The resulting thermal index of such a combination will exceed 220°C (EIC and ASTM). 

Recently, partial discharge has become a concern in lower voltage motors, especially for eMobility applications. These motors operate by variable speed drives (VSD). These drives control the motor speed using high frequency square waves as opposed to conventional sinusoidal waves. The frequencies incorporated are often up to 20 kHz, as compared to the conventional 50 or 60 Hz. VSD’s sometimes called ‘inverters’ offer great advantages such as high efficiency and fast accurate speed control.

Inverters are associated with problems such as voltage overshoots and reflected waves:

  • Voltage overshoots vary in intensity but are often characterized by fast rise times.  
  • Reflected waves are a result of mismatched impedance.  

The reflected wave becomes additive with another incoming wave resulting in a waveform that is twice the intended voltage.  Since these waves are fast rise time, there is insufficient time for the energy to be dispersed among the windings of the motor. This creates high turn to turn potential between adjacent strands of magnet wire. These increased voltages are high enough to create partial discharge in the windings within the motor.

Partial discharge (PD) is defined as an ‘electrical discharge that does not completely bridge the space between two conducting electrodes.’ Areas with voids, cracks or imperfections is location where the partial discharge occurs.
Partial discharge occurs in void spaces in insulation and results in the damaging of the insulation system.

Protection by Encapsulation
ELANTAS offers a full package of insulation materials to improve lifetime and endurance under the influence of high voltage surges or partial discharge.

One solution to partial discharge is to remove the air where it occurs. Full encapsulation or potting of a motor with ELAN-tron® MC 62/W363 or ELAN-tron® MC 622/W363 is a great way to implements this solution.

Protection with Co-Shield® System
However, when full encapsulation is not being used, the best performance, is to utilize the Co-SHIELD® system. It provides superior resistance to partial discharge through the combination of wire enamels such as those described above impregnation resin such as the CORONA-Protect resins and ELAN-Film as flexible insulation material.

ELANTAS has developed magnet wire enamels which have demonstrated under pulse endurance testing longer life. The enamels provided by ELANTAS are the Corona Clear product and Allotherm CR along with the Tongmid CR products.

For an impregnation resin, the Corona Protect® 82-80A3 has shown that this has provided the longer life for EV motors particularly commercial electric vehicle applications.

ELAN-drive battery products

Gap Filler

The electrochemical reactions in battery cells for e-cars are highly dependent on temperature. That property makes it essential to maintain the battery cells within a healthy temperature window of operation.

In addition, minimizing the temperature differences within the module and pack is crucial to ensuring longevity. Unwanted side reactions in local hot spots within the pack decrease cell capacity and result in continuing loss of overall capacity. Management of the heat flow, for example with the help of ELANTAS gap fillers of silicone or polyurethane chemistry is therefore critical.

(Thermal) Adhesives

In eMobility applications, the increasing thermal management challenges require heat dissipation across bondlines.

  • Adhesives are a proven light-weight, effective bonding solution.
  • They must reliably fulfil fixation and provide a path for effective heat transfer.

Examples for thermal adhesives applications are the fixation of cooling elements or heat sinks to the heat source and the cell to cell fixation.

For such applications, ELANTAS epoxy or polyurethane products are highly recommended. They are suitable for most substrates and can be machine applied or dispensed manually, if preferred.

The complexity of battery packs in electronic vehicles involves several electronic or electric elements that require protection by polymeric coatings. ELANTAS is experienced in various chemistries and application methods, for example:

  • The printed cuircuit boards of battery management system at the module or pack level are frequently coated with polymeric resins of various thicknesses to protect them and guarantee longevity.
  • Resin coatings are also used on busbars connecting the modules in the pack. Here, the coatings ensure perfect insulation of the conductors to guarantee safe and long-term use under high-voltage conditions in today’s batteries. 

Back to Top


The anticipated lifetime of a battery pack is about 15 years. Therefore, the housing and all connection points to the pack need to securely sealed.

  • ELANTAS sealants protect the valuable interior battery components from water and dirt, which could harm performance.
  • They have been shown to withstand stress factors from varying weather conditions and vibrations, as simulated in automotive exposure tests.

Battery applications ELAN-drive

A battery in the field of electromobility serves as the energy store for bikes, scooters, cars, ships or aircrafts. It is always composed of many, sometimes very many, individual cells. The clever parallel and serial connection of cells to modules and packs delivers the desired battery voltage and current.

The cell formats found today are:

  • Cylindrical;
  • Pouch and
  • Prismatic.

Despite the different geometries, the following points are equally important for all cell types during assembly and use:

  • Effective thermal management is an important prerequisite for long and consistent performance of a battery. Thermal interface materials ensure effective heat flow.
  • At the same time, cell housings shall be insulated electrically. For this reason, a thin layer of an insulative coating can be applied. 
  • For fixation reasons, either cell-to-cell or cell-to-frame, adhesives can be applied.

Factors for polymer material selection and durability 

To meet the above challenges in cell assembly, different polymer materials are used. When selecting them, the local options of product application and the desired properties must be taken into account.

In the final assembly, durability plays an important role:

  • End users expect the most stable power output possible during use (driving) and
  • fast recharging over the entire service life of the battery.
  • The polymer resins must therefore exhibit long-term stability against varying stress factors, such as vibration, temperature and humidity. 

ELANTAS offers a wide chemical range of polymeric resins to meet all requirements during application and in the final product.

Gap Fillers

Casting & Potting Resins

Thermal Greases

Thermal Adhesives

A battery module consists of individual cells joined together and is a modular building block for a battery pack. The pack can consist of six, eight or more modules, for example. Adapted to different sized electric cars of some manufacturers, a scaling can be done by more or less modules for each pack

Thermal management is also particularly important in the pack. 
The individual modules are mounted on a base plate, which is tempered by coolant.

Good heat transfer between each individual module and the base plate or cooling plate must be ensured. This can be achieved by ELANTAS gap fillers:

  • Gap fillers fill the small gap between the module and the plate, thus displacing air as a thermal insulator.
  • At the same time, the flexibility of the gap fillers compensates for unevenness in the structures.
  • Effective contact between the underside of the module and the cooling plate is important during the period of use. Vibrations and temperature changes during operation must not weaken the adhesion of the gap filler.

TIM (Thermal Interface Material)

Gap Filler

Casting & Potting Resins

Thermal Grease

Thermal Adhesives

Electronic devices continuously analyze a battery’s important operating parameters.
These include temperature monitoring of the modules and also individual cells. Voltage and current flow must be monitored during charging and discharging to ensure that the pack is always in the optimal operating state.

The monitoring and control is done with the help of numerous sensors and one or more battery management systems.

Protection of sensitive battery control electronics 

These electronic components are integrated in the battery-pack housing and, like any sensitive electronics, must be protected:

  • from vibration damage,
  • moisture, and also
  • exposure to excessive temperatures. 

ELANTAS has many decades of experience in protecting sensitive control electronics. The offer includes different base chemistries and in terms of thickness, ranges from

  • Very thin conformal coatings 
  • thick film coatings
  • potting of components.

The curing of the polymer coating can be achieved by

  • UV light,
  • by heating, and/or moisture curing

The curing reactions follow different mechanisms and can be tuned according to the needs of our customers.

Dielectric Cell Coating / Battery Component Coating

Conformal Coatings



Every assembled cell system requires a housing for protection from external influences such as moisture and corrosive contamination as well as for safe handling and transport.

In electric cars, battery enclosures often consist of an aluminum tray and a cover,sometimes made of another lighter plastic material such SMC or GFC.Other electric vehicles - from electric scooters, robots, boats, aircraft - require housings adapted to the conditions of use and the weight of the battery.

Electrical connections or cooling liquids are fed through the housing wall or the lid of a battery housing. In addition to sealing the cover itself, all feedthroughs must be carefully sealed against ingress of moisture and water with long-term stability.

At the same time, the sealant must withstand the vibration load during operation and the temperature expansion of the base material without damage.

ELANTAS offers:

  • sealants on various chemical bases for many material substrates and different requirements,
  • Adhesives with sealing effect to help structural fixation and to save weight.
  • ELANTAS products are available for application with automatic dispensing equipment as well as for manual application from cartridges.

Power electronics applications ELAN-drive

Every powertrain contains an inverter that converts the DC current from the battery into the AC current needed to power the motor. The inverter is essential to the performance of the motor and influences driving behavior. During the power conversion process, heat is generated, which can have a negative effect on the performance and longevity of the inverter. 

With the ELAN-tim product range, ELANTAS offers thermal conductive casting and potting materials that support the active heat management in the inverter.

Another key part of the inverter is a printed circuit board as a control unit, which steers the processes in the inverter.

Here ELANTAS offers a broad range of conformal coatings to protect the circuit boards against environmental impacts and insulate them.

The HV battery is powering the motor and the other systems in the vehicle. Not every system needs a high voltage: certain components, like the entertainment or safety systems, run on lower voltages.

For this purpose, DC/DC converters are present, which changes the voltage accordingly.

During the conversion process, heat is generated that needs to be transferred away from the sensitive components as overheating can lead to failure and reduced lifetime.

With the ELAN-tim® product group of thermal conductive materials, ELANTAS offers thixotropic gap filler and free-flowing casting and potting materials that help to optimize the heat management in the powertrain. The material can be applied with standard mass-production equipment.
