Abstract
A motor control circuit includes a control circuit configured to control a switching operation of an inverter circuit, the inverter circuit being configured to supply an alternating current power to a motor, and includes a determination-information generating circuit configured to generate at least one determination value that conveys information on whether the motor malfunctions or deteriorates. The motor control circuit includes a determination circuit configured to determine whether the motor malfunctions or deteriorates based on the determination value to output, as an interrupt signal, a signal indicating that the motor malfunctions or deteriorates to the control circuit.
