A motor drive apparatus includes a control assembly that controls driving of a motor. The control assembly includes a controller that outputs a drive signal instructing a drive amount of the motor, a drive that supplies electric current, supplied from an external power supply, to the motor based on the drive signal output from the controller, a current detector that detects electric current flowing through the drive unit, and a first temperature detector that detects temperature of the drive unit. The control assembly calculates a heat storage amount stored in the control assembly at a predetermined cycle, and when the calculated heat storage amount is larger than a predetermined threshold, the control assembly outputs the drive signal that instructs a drive amount smaller than the drive amount at the time of calculation.
