ABSTRACT:
In order to control an electromotive drive, a control unit has control modules for controlling half-bridge end power stages. Two of the control modules are pre-configured for alternatively controlling a commutator motor or a brushless electric motor via two half-bridge end power stages. A third control module can be subsequently configured to control a third half-bridge end power stage or two individual switching elements. An electromotive drive ideally can be configured with the stated control unit.
