Brushless DC-motor for use in motor vehicle, has rotor with permanent magnet poles separated by boundaries which extend with respect to axial extension of rotor axis to be inclined along length of rotor for entire/half slot pitch of stator

摘要

The motor has a stator (1) with three teeth (2) separated from a rotor (4) by an air gap (3) and from each other by slots (5), where the teeth have auxiliary wedges (6). The rotor has permanent magnet poles separated in a peripheral direction of the rotor, by boundaries between the poles. The boundaries extend with respect to an axial extension of a rotor axis for being inclined, along length of the rotor, for an entire/half slot pitch.
