The present invention relates to a motor driving device, and a vehicle having same. The motor driving device according to an embodiment of the present invention comprises: a motor; and an inverter for outputting alternating-current power to the motor, wherein the motor comprises a six-phase motor, and the inverter comprises three legs connected in parallel to each other, each leg including three switching elements connected in series. Accordingly, the size of the inverter and the number of times the inverter switches can be reduced. La présente invention concerne un dispositif d'entraînement de moteur et un véhicule le comportant. Le dispositif d'entraînement de moteur selon un mode de réalisation de la présente invention comprend : un moteur ; et un onduleur destiné à délivrer une puissance en courant alternatif au moteur, le moteur comprenant un moteur à six phases, et l'onduleur comprenant trois branches reliées en parallèle l'une à l'autre, chaque branche comprenant trois éléments de commutation connectés en série. Par conséquent, la taille de l'onduleur et le nombre de fois où les commutateurs d'onduleur peuvent être réduits. 본 발명은 모터 구동장치, 및 이를 구비하는 차량에 관한 것이다. 본 발명의 실시예에 따른 모터 구동장치는, 모터와, 모터에 교류 전원을 출력하는 인버터를 포함하고, 모터는, 6상 모터를 포함하고, 인버터는, 서로 병렬 접속되는 3개의 레그를 포함하며, 각 레그는, 직렬 접속되는 3개의 스위칭 소자를 포함한다. 이에 따라, 인버터의 크기 및 인버터의 스위칭 횟수를 저감할 수 있게 된다.
