Abstract

PURPOSE:To prevent the occurrence of a commutation signal of a wrong rotatory direction by changing the set point which determines the commutation timing of an inverter. CONSTITUTION:A reverse rotary signal BW for bias is input to a comparator 1 when it gives a reverse rotation and a normal rotary signal FW for bias is input to a comparator 2 when it gives a normal rotation. With the FW for bias which is input only when in normal rotation, the output of a commutation signal R due to the influence of an incidental change of angle, noise or the like can be prevented. In the same way, the output of a commutation signal F due to the influence of an incidental change of angle, noise or the like can be prevented with the BW for bias which is input only when in a reverse rotation.
