Stator tooth for stator core e.g. of brushless permanent magnet motor, has tooth surface with one or more flat segments extending from one end of first edge formed by slot opening to end of second edge

摘要

The device has a first edge formed by a first stator slot opening (16) and extending from an outer edge of the stator core according to a first radial distance, a second edge formed by a second stator slot opening and extending from an outer edge of the stator core according to a second radial distance and a tooth (20) surface (26) extending from one end of the first edge to one end of the second edge with one or more flat segments.
