Brushless electronically-commutated DC motor for maritime applications, has permanent magnets arranged on circular path around rotor attached by bearing on base of pot-shaped stator

摘要

The stator (1) is pot-shaped, and the pot wall (2) carries at least one ring (3) of magnetic coils. Control circuitry (9) is arranged on the inside of the pot base (6). The bearing (7) for the rotor (8) is arranged on the pot base. Each permanent magnet (15) is arranged on the rotor, on a circular path defined by the circumference of the rotor, transverse to the rotor plane and parallel to the rotary axis of the rotor, defined by the bearing.
