MOTOR CONTROL DEVICE

摘要

The invention addresses the problem of obtaining a motor control device capable of, during motor operation from at zero speed rotation to at a high-speed rotation, detecting a medium-level motor abnormality such as, for example, a motor interlayer short-circuit and error increase in a position sensor unit. The motor control device (100) detects the current value of output current output to a motor (310) and controls the current value so as to correspond to a target torque. The motor control device (100) has a motor abnormality determination unit (140) for calculating a motor operation state value on the basis of the current value of output current output to the motor (310) during the operation of the motor (310) and the voltage value of output voltage and for determining from the calculated motor operation state value whether an abnormality occurs in the motor (310) or not.
