Pseudo Direct Drive

Traction Motor

Magnomatics' Pseudo Direct Drive (PDD®) offers significant advantages over conventional permanent magnet motor/generator technology, achieving a step-change in continuous torque density and highest efficiency.

 

This allows the motor to directly drive many loads where conventionally a motor and gearbox combination would be employed.

 

An ideal application will have high continuous torque at relatively low speed.
