摘要
The drive motor located on the drum shaft is a synchronous motor activated by permanent magnets (3). The stator of the motor is equipped with a coil supplied with a current by a transformer. The tooth crests of the stator poles have a specially dimensioned curvature at least in their edge sections. As a result of the dimensions, the air gap (4) between the permanent magnet and the tooth flanks is 4-6 times greater than the air gap between the permanent magnet and the tooth crest middle.
