| 发明名称 | Motor control device | ||
| 摘要 | Provided is a motor control device that includes an inverter circuit that includes a plurality of P-side switching elements and a plurality of N-side switching elements and drives a motor via a plurality of motor terminals; a first dynamic brake that brakes the motor by turning on all the phases of the plurality of P-side switching elements or turning on all the phases of the plurality of N-side switching elements; a second dynamic brake that brakes the motor by connecting dynamic brake resistors between the motor terminals; and a control unit that switches, according to the motor speed, between the first dynamic brake and the second dynamic brake, which are the dynamic brakes that brake the motor. | ||
