A motor controller includes a temperature estimator that estimates a temperature of an element in a motor driver circuit that drives a motor, or a temperature of a winding of the motor, and a non-volatile memory that provides a first area and a second area for storing the estimated temperature. The temperature estimator writes the estimated temperature to both of the first area and the second area.
