摘要： PROBLEM TO BE SOLVED: To provide a motor control device which does not need to set a waiting time up to stable rotating sensor actuation to wait for sensor actuation when the control device is shifted to a wake-up mode from a sleep mode and a voltage is applied to the rotating sensor, and is improved in the responsiveness at the actuation. SOLUTION: In the motor control device 1, power is fed from a power-input positive (+) terminal of the rotating sensor 51 (Hall ICs 53, 54) by a rotating sensor power feed circuit 12. Then, when a control unit (CPU 21) is shifted to the wake-up mode from the sleep mode, the control unit starts to feed power to the rotating sensor 51 from the rotating sensor power feed circuit 12, and after a voltage detector 25 detects that a level of a power supply voltage fed to the rotating sensor 51 from the rotating sensor power feed circuit 12 is a prescribed voltage level or above, starts to perform processing of motor rotation detection (interruption processing) in a motor rotation position detection unit 24.

摘要： PROBLEM TO BE SOLVED: To provide a motor controller which avoids the occurrence of such a fault that a voltage is kept applied to the terminal of a motor in case that a fault occurs at a motor voltage detecting part and that welding occurs at a relay contact in that state.
SOLUTION: This motor controller 1 is provided with a voltage detection failure determinator 16, which mutually monitors a motor voltage signal outputted from a motor voltage monitor 13 and a motor revolution signal outputted from the motor revolution detector 14. Then, the voltage detection failure determinator 16 determines that there is failure in a motor voltage detector (a section composed of a motor terminal voltage detecting circuit 23 and the motor voltage monitor 13) in case that a signal, which shows that there is no motor terminal voltage (a drive voltage is not applied to the motor) is outputted from the motor voltage monitor 13, in a state where a signal, which shows that the motor is rotating, is outputted from the motor revolution detector 14.
