ABSTRACT:
In an electric drive for a DC shunt propulsion motor which is supplied from a battery, the armature winding is connected to the battery, and the field winding is connected to the battery via an electronic DC control element. The electronic DC control element is associated with the field winding and also serves as a control element for charging the battery. The DC control element is further equipped with a voltage control device in addition to a current control device. A multiposition switch is arranged so that when the switch is in one position the field winding is connected via the electronic DC control element to the battery, and when the switch is in another position, the electronic DC control element is shunted across the battery.
