Magnetic circuit of an electrical, rotating, permanent-magnet machine

摘要

The invention relates to a magnetic circuit of an electrical rotating machine, having permanent magnets arranged between and outside the machine poles. The invention aims to achieve a qualitative production simplification, especially in the course of the assembly work involved in the stator magnet rim, with a simultaneous improvement in the electrical and magnetic characteristics. This object is achieved in that the machine poles are formed from two symmetrical pole halves whose separating slot lies in the axial plane of the machine, and in that the pole halves, which lie side-by-side, are provided on the facing sides with mutually opposite axial grooves in which two expanding wedges are accommodated, whose apexes are located on opposite sides and whose edges are supported against one another and the other edges are supported against the groove bases.
