Abstract
A motor controller that outputs a drive signal to a direct-current brush motor to drive the motor is provided. The motor controller includes a drive signal generating section that generates the drive signal. The drive signal generating section generates the drive signal by superimposing on a direct-current voltage a compensation voltage for generating a compensation torque that can cancel rotation torque fluctuations in a no-load rotation state of the motor.
Claims5
A motor controller that outputs a drive signal comprising a direct current voltage to a direct-current brush motor to drive the motor, the motor having a no-load rotational state and comprising a brush to which the direct current voltage supplied by a battery is applied, the motor controller comprising:
- a drive signal generating section that generates the drive signal by superimposing on the direct-current voltage a compensation voltage, the compensation voltage generating a compensation torque to cancel torque fluctuations in the no-load rotation state of the motor.
A method for controlling a direct-current brush motor having a no-load rotational state and comprising a brush to which a direct current voltage supplied by a battery is applied, the method, comprising:
- generating a drive signal output to the motor to drive the motor, wherein the drive signal is generated by superimposing on the direct-current voltage a compensation voltage, the compensation voltage generating a compensation torque to cancel torque fluctuations in the no-load rotation state of the motor.
