A motor control device includes a motor, a control portion controlling the motor, estimating a heating temperature of the motor on the basis of an electric current value and an energizing time period or a stopping time period of the motor, and restricting an electrification of the motor in a case where the estimated heating temperature becomes equal to or greater than a limit value, and a temperature sensing device for detecting a temperature of a predetermined portion of a vehicle, wherein the control portion estimates an initial temperature of the motor when an engine is started on the basis of a temperature signal outputted from the temperature sensing device and determines the limit value on the basis of the estimated initial temperature. |
