Abstract
An electric road motor vehicle with a switchable winding electric motor propulsion system, a switchable winding electric motor propulsion system in an electric road motor vehicle, and a switchable winding electric motor propulsion system for a motor vehicle. For the optimization of an electric motor propulsion system of a vehicle, the electric motor equipped with a rotary field winding is connected through a switching system to an electronic converter, so that due to the switching system, the number of phase windings of the rotary field winding to be connected to the individual output connections can be changed. The switching system is controlled by a control circuit through a actuator. The control circuit also controls the converter and deactivates the driver currents fed to the rotary field winding, while it switches over the switching system through the actuator. The switching system can thereby be made simpler and smaller. The switching system including the actuator is combined into a unit with the electric motor.
