摘要

The motor (1) has a stator (2) comprising a number of stator poles i.e. permanent magnets stator poles (3a-3d), with slats that are connected with each other by bridges. An armature (4) includes a number of quiescent anchor teeth (z1-z6) that are arranged at a periphery of the armature. Grooves are arranged between the number of quiescent anchor teeth. A winding (9, 9a, 9b) is provided on each of the anchor tooth as a single-tooth winding. The winding is formed as a concentrated two-fold winding. Width of carbon brushes (8a, 8b) is smaller or equal to width of one slat.
