Ironless Composite Stator

ThinGap’s core technology is it’s proprietary ironless composite stator.


TG Series Architecture

  • 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.

TG Performance Relative to Conventional Motors

High torque production and up to twice the power-to-weight ratio of conventional brushless motors.
