Abstract: The disclosure provides a motor and an energy conversion device. The motor includes a motor coil having x sets of windings. A number of phases of the x sets of windings is mx. In each of the x sets of windings, each phase winding includes nx coil branches. A first end of each of the nx coil branches is connected with a first end of a coil branch separated from the coil branch by an electrical angle of 360 degrees, to form mx phase endpoints. A second end of each of the nx coil branches of each phase winding is connected with a second end of a coil branch separated from the coil branch by an electrical angle of P*(360*k1+360/mx) degrees to form nx neutral points, nx≥mx≥2, nx≥3, p=±1, 1≤k1≤(nx−1), and mx, nx, and k1 are integers.

Abstract: The present disclosure relates to the technical field of vehicles, and provides a vehicle and an energy conversion device and a control method therefor. The energy conversion device includes a motor controller, a bus capacitor, a first switch module, a motor, and a second switch module. By controlling the first switch module and the second switch module to be turned on/off, a motor driving circuit can be formed by a battery pack, the first switch module, the bus capacitor, the motor controller, and the motor, and a charging and discharging circuit can be formed by the battery pack, the second switch module, the motor, the motor controller, and the bus capacitor.
