- Electrification
- Molding Compound for Stator Coil Encapsulation
Molding Compound for Stator Coil Encapsulation
and improving the functionality
of in-vehicle drive motors
Advantage
- Replaces insulation paper by molding layer of 150-300 micron thickness.
- Excellent narrow space filling(filling coil gap).
- Good Environmental resistance by encapsulation.
- High thermal conductivity grade available.
* Suitable not only for drive motors, but also for auxiliary motors and axial gap motors!
Conventional process
Insulating paper + liquid resin immersion, etc.
