PROBLEM TO BE SOLVED: To allow for detection of a voltage between motor terminals regardless of the drive frequency of a motor.SOLUTION: A motor controller (motor drive unit 200) for controlling a current supplied to a motor 9 by duty control includes a drive control unit 220 performing on/off control of a current supplied to a motor 9 at a first cycle, an off control unit 230 performing off control of a motor at a second cycle longer than the first cycle, independently from the on/off control by the drive control unit 220, and a voltage acquisition unit (A/D conversion unit 210, sampling unit 240) for acquiring the voltage between motor terminals during off control by the off control unit 230. |
