Ironless Composite Stator
ThinGap’s core technology is it’s proprietary ironless composite stator.
- Electromagnetic coils embedded in a composite structure
- High ratio of conductor to total stator volume
- Thin radial profile facilitates lightweight rotor designs
- High power density
- High torque density
- Excellent convective cooling
- Zero cogging for smooth and vibration free operation
- Quiet torque output
- Excellent motor design flexibility
High Energy Lightweight Rotor Designs
Dual rotating rotor completes the magnetic flux circuit without both Eddy current or iron losses.
