ABSTRACT:
A circuit arrangement for controlling the operation of a d.c. motor. The circuit includes a controller having a reference potential input and a control input. The control input is used for controlling the speed of the motor. A plurality of switches allows the circuit arrangement to enable the controller to control the motor when the motor is to operate in one direction. The plurality of switches further causes the controller to be unable to control the motor when the motor is to be operated in a second direction. This arrangement improves speed control accuracy.
