PDD® traction motors deliver significant torque in a small volume, giving increased flexibility to vehicle designers. Through a fully integrated contactless magnetic gear the motor produces high torques at speeds appropriate for direct-drive of vehicle wheels.

The removal of mechanical gear stages increases efficiency, reduces maintenance requirements and increases reliability.


Due to its high torque capability the PDD® can produce sufficient torque within the limited space of a wheel-hub and due to its large airgaps, is able to withstand the severe shock loads associated with wheel hub applications.
