PROBLEM TO BE SOLVED: To adequately control the motor operation by identifying an error of voltage value estimated on the basis of the detected voltage value and current value, and then impressing the predetermined voltage to a coil depending on the motor operating condition through reflection of the identified error. SOLUTION: A motor control device 10 once estimates a voltage value of power supply to a certain value. On the basis of the estimated voltage value, a voltage application control part 204 impresses the voltage for detection. If there is an error between the estimated voltage value and the true value, a voltage for detection of the voltage value that is different from the preset value is impressed. An error of the voltage for detection impressed can be detected with a current flowing into a coil depending on the voltage. Therefore, a voltage compensating part 206 can identify an error of the estimated value of the power supply voltage based on such error. As explained above, the voltage application control part 204 can apply the adequate voltage to the coil by reflecting the identified error. |
