Proven in challenging environments, the Pseudo Direct Drive (PDD®) offers a step-change in performance and efficiency over permanent magnet motor/generator technology.


  • Highest continuous torque density

  • <60% size and mass of a PM machine

  • Highest efficiency

  • Fault tolerant

  • Built-in passive torque fuse (protecting drive-trains)

  • Low maintenance

  • High reliability


The dramatic increase in torque density allows the motor to directly drive many loads where conventionally a motor and gearbox combination are employed.
