CONTROL DEVICE FOR BRUSHLESS DC-MOTOR MOTOR DRIVER, CONTROL METHOD, CONTROL PROGRAM, AND BRUSHLESS DC-MOTOR MOTOR DRIVER

摘要

This control device (22) for a motor driver (16) for a brushless DC motor (5) is provided with a processing unit (23) that obtains the number of pole pairs for the brushless DC motor (5) in the output value from a rotation angle sensor (20) when a rotor (19) of the brushless DC motor (5) has been set to a predetermined electrical angle, and sets the average value of the obtained output values to the motor driver (16) as an offset value for modulating the phase of the current supplied to the brushless DC motor (5) by the motor driver (16) on the basis of a signal from the rotation angle sensor (20).
