To ensure that an inverter circuit is not started when a connection fault or miswiring is present, and to make it possible to prevent the inverter circuit from being damaged, the present invention is provided with a motor (2), an inverter circuit (40) for driving the motor, and a control circuit (50) for controlling the inverter circuit (40). The inverter circuit (40) has a serial connection between high-side switching elements (Q1-Q3) and low-side switching elements (Q4-Q6), and the control circuit (50) is configured so as not to start the inverter circuit (40) when the voltage is irregular at the points of connection between the high-side switching elements (Q1-Q3) and the low-side switching elements (Q4-Q6). |
