| description | The present invention relates to a motor driving device and a vehicle with the same. According to an embodiment of the present invention, the motor driving device comprises: an output current detection unit for detecting an output current flowing in a motor; an inverter comprising a plurality of switching elements and outputting an alternating voltage to the motor; and an inverter control unit for controlling the inverter based on the output current. The inverter control unit estimates the temperature of a magnet in the motor based on the output current flowing in the motor and controls an output of the motor to be small when the estimated temperature exceeds a reference value. Accordingly, it is possible to vary the output of the motor based on the estimated temperature without a separate temperature sensor.
본 발명은 모터 구동 장치, 및 이를 구비하는 차량에 관한 것이다. 본 발명의 실시예에 따른 모터 구동 장치는, 모터에 흐르는 출력 전류를 검출하는 출력 전류 검출부와, 복수의 스위칭 소자를 구비하고, 모터에 교류 전압을 출력하는 인버터와, 출력 전류에 기초하여, 인버터를 제어하는 인버터 제어부를 포함하고, 인버터 제어부는, 모터에 흐르는 출력 전류에 기초하여 모터 내의 마그네트의 온도를 추정하고, 추정된 온도가 기준치 초과인 경우, 모터의 출력이 작아지도록 제어한다. 이에 따라, 별도의 온도 센서 없이, 추정된 온도에 기초하여, 모터의 출력을 가변할 수 있게 된다. |
