Circuit arrangement for controlling electric motor

摘要

A circuit arrangement for controlling an electric motor 923) has switching devices provided by means of which the motor can be short-circuited. A bridge circuit consisting of at least four further switching devices is provided for controlling the motor in the bridge cross-branch. By operation of the further switching devices, one of the two bridge diagonals is switched to be current-conducting. An electrical resistance is provided via which the motor can be short-circuited by operation of the switching devices. The switching devices are designed at least as two controllable switches. They are designed as semiconducting relays.
