ELEKTROMOTOR.

摘要

The electromotor has a permanently-magnetic rotor. Each stator pole (3) has one permanently-magnetic rotor pole associated with it. The distance between the centres of adjacent permanently-magnetic poles differs from the distance between the centres of adjacent stator poles. Detectors (38) are mounted on the stator that detect the relative position of stator (2) and rotor (32). Electronic switching devices (40) are controlled by the detectors and switch in one or more of the conductors (windings) on the stator when the relative positions are correct. The advantage lies in easy control and high efficiency.
