Electronically commutated three-phase motor

摘要

Devices and arrangements for electronically commutated three-phase motors are proposed, in particular a split-cage motor having a device for limiting the voltage of the lagging turn-off voltage of the winding strands. In addition, electronically commutated three-phase motors are proposed in which a closed stator winding is arranged on the stator, and is constructed as a lap winding or wave winding, or a stator winding having mutually isolated winding strands is arranged, the stator winding always having a current flowing through it which has a square wave form.
