High-density DC motor combination

maxon motor has introduced a combination of a 4-pole brushless DC motor with a sealed planetary gearhead and an inductive encoder for demanding subsea applications.

Constructed with a single tube stainless steel housing with laser welded flanges, this 4-pole brushless DC motor offers high levels of robustness and can deliver 90 W of power but has a diameter of only 22 mm.

High end rare earth magnets and maxon’s winding technology give the brushless motor the advantage of being powerful and also highly controllable. The winding gives zero magnetic cogging and the low rotor inertia allows for rapid acceleration. The motor also includes maxon’s EASY 16 mm inductive encoder that is also sealed and therefore suitable for use in harsh electrical or environmental conditions.

Reducing the motor speed and increasing the torque is a 26 mm planetary gearhead with rubber seals fitted to the bearing for increased protection. The entire combination of parts forms a powerful, controllable brushless DC servo drive.
