A control device 10 for a motor 1 includes: a processor 20 for generating a control command for power supplied to a coil 2 of the motor 1; an inverter circuit 30 for controlling, based on the control command of the processor 20, the power supplied to the coil 2 of the motor 1; and a switching circuit 60 disposed between the inverter circuit 30 and the coil 2 of the motor 1, and configured to switch between an energized state where the inverter circuit 30 and the coil 2 are energized and a non-energized state where the inverter circuit 30 is electrically disconnected from the coil 2. The processor 20 is configured to give the switching circuit 60 a first disconnection command to switch from the energized state to the non-energized state, when rotation of the motor 1 is detected in a state where the power is not supplied to the coil 2.
