Magnetically Geared

15kW & 25kW Thrusters

Magnomatics' thrusters are oil-filled (biodegradeable) and presure 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.

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.

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.
