Abstract

A control device is for a motor, especially a brushless DC motor. The control device contains a bridge circuit for generating a rotating field for the motor and a sensor system for detecting a position of a rotor of the motor, a control signal for the bridge circuit being derivable from the signal representing the rotor position. The sensor system includes an absolute value transmitter which detects the absolute position of the rotor and which is configured to derive at least one incremental signal from the absolute position and to make it directly available to a control component for controlling the bridge circuit for commuting the motor.
