CONTROL DEVICE FOR A MOTOR AND METHOD FOR CONTROLLING SAID MOTOR

摘要

The invention relates to a control device (1) for a motor (2), especially a brushless DC motor. The control device according to the invention comprises a bridge circuit (6) for generating a rotating field for the motor (2) and a sensor system for detecting a position of a rotor of the motor (2), a control signal for the bridge circuit being derivable from the signal representing the rotor position. The sensor system comprises an absolute value transmitter (3) which detects the absolute position of the rotor and which is designed to derive at least one incremental signal (sH1, sH2, sH3) from the absolute position and to make it directly available to a control component (5) for controlling the bridge circuit (6) for commuting the motor (2).
