Abstract
A motor control device includes an assistive torque current calculation unit that obtains a current that needs to be supplied to a motor, and an overheat protection limit calculation unit that obtains an overheat protection coefficient when current obtained from the assistive torque calculation unit flows through using an overheat protection feature, and obtains a current actually supplied to the motor using the obtained overheat protection coefficient, wherein the overheat protection feature: shows a relationship between how large the current is, and the overheat protection coefficient, where the current is regulated by taking into account an effect that heat generated by a part out of a plurality of parts disposed on a pathway which the current that is supplied to the motor flows through has on an ambient temperature, and an effect that heat generated by other parts out of the plurality of parts has on the ambient temperature.
