DISC ROTOR MOTOR

摘要

A disc rotor motor is demonstrated, having at least one stator that has at least one electrical stator winding and stator teeth, which have a tooth neck composed of a soft magnetic powder composite, and having at least one disc-shaped rotor, which has permanent magnetic poles composed exclusively of ferrite magnets at least for producing torque, with the rotor and stator oriented parallel to each other and spaced apart from each other by an axial gap. In order to find an optimum between costs, weight, and overall size as well as power and torque density, the invention proposes that the stator teeth each end in a tooth end that adjoins their tooth neck and is composed of a soft magnetic powdered composite, which tooth end widens out in its cross-sectional area in comparison to the tooth neck.

主权项

1. A disc rotor motor, comprising:
at least one stator that has at least one electrical stator winding and a plurality of stator teeth, each of the stator teeth having a tooth neck composed of a soft magnetic powder composite, wherein each of the stator teeth ends in a tooth end that adjoins a respective tooth neck and is composed of a soft magnetic powdered composite, and each tooth end widens out in its cross-directional area in comparison to the respective tooth neck; and at least one disc-shaped rotor having permanent magnetic poles composed exclusively of ferrite magnets at least for producing torque, wherein the rotor and stator being are oriented parallel to each other and spaced apart from each other by an axial gap.
