Direct drive high torque, low speed e-machine

Magnomatics’ patented Pseudo Direct Drive (PDD®) offers a significant advance over conventional permanent magnet motor/generator technology, achieving a step-change in continuous torque density compared to that of equivalently cooled PM machines while maintaining very high efficiency.

This dramatic increase in torque density allows the motor to directly drive many loads where conventionally a motor and gearbox combination would be employed.  Ideal application will have high continuous torque at relatively low speed.

It is highly suitable for applications ranging from aerospace actuation, marine propulsion drives through to direct drive utility scale wind turbines and rail traction systems.
