Abstract
There is provided a motor controller including: a voltage generator that generates a voltage applied to a motor; a temperature detector that detects a temperature of a circuit; a rotation speed detector that detects a rotation speed of the motor; and a voltage controller that controls the voltage generator so as to generate a voltage of a duty ratio based on a speed instruction value, and that, in cases in which a temperature of an element configuring the circuit, computed based on the temperature of the circuit detected by the temperature detector, the rotation speed of the motor detected by the rotation speed detector, and a load of the circuit, reaches a predetermined threshold value or above, controls the voltage generator so as to generate a voltage of a duty ratio that is lower than the duty ratio based on the speed instruction value.
