25kW E-ROV Thruster

A high-speed PM motor is coupled with a magnetic gear to produce a low-speed, high torque output which is optimised to the propeller performance curve and the thruster is smaller than an equivalent direct-drive motor.
Magnomatics’ thrusters are oil-filled (bio-degradeable) and pressure balanced for deep sea operation. They combine a magnetic gear and permanent magnet motor arranged to provide a hermetic seal between the motor and the sea water.
The magnetic gear also provides effective anti-jamming with its passive reset torque-fuse, protecting the drive-train from the loads associated with striking solid objects, ropes etc
