Abstract:
A motor control device of controlling a motor unit that drives a wheel is provided. The device include a temperature sensor that senses a temperature of a motor coil, and a motor current limiter. The motor current limiter sets a plurality of threshold values of the temperature sensed by the temperature sensor, sets a current limiting condition that are different from each other for respective sectioned temperature ranges defined by the threshold values, and limits a current for the motor unit according to the current limiting condition for the temperature ranges to which the temperature having been sensed belongs.
