Abstract

Permanent-magnet-excited ac servo motors can be produced usefully with tooth-coil windings; they allow an increase of the torque density due to their compact construction. The winding systematics and the winding variants, interesting for ac servo motors, are introduced. The steady-state behavior of the ac servo drive is calculated analytically in dependence of the winding variant. The influence of the winding variant on the M(n)-characteristic is discussed in examples. A comparison between calculations and measurements verifies the represented modeling.
