Electrical machine, especially 3-phase machine, with auxiliary winding has additional winding(s) associated with stator; voltage can be tapped between from additional winding whose frequency and/or voltage can be regulated to defined values

摘要

The electrical machine has three stator windings for connection to a battery (22) via an inverter and at least one additional winding associated with the stator. A voltage can be tapped between the two connections of the additional winding whose frequency and/or voltage level can be regulated to definable values.
