Description
technical field [0001] The present application relates to the technical field of automobiles, in particular to an automobile, a motor and an energy conversion device. Background technique [0002] At present, new energy vehicles use permanent magnet synchronous motors, and the stator windings of the permanent magnet synchronous motors generally adopt star connection. Generally speaking, the connection method of the neutral wire of the star-connected motor winding is relatively simple, and the coil connection method of the motor winding is not flexible, which makes it difficult to adjust the working power of the motor using the star-connected method. [0003] Now Cheng is waiting to develop a new type of motor structure to make the adjustment of the working power of the motor more flexible. Contents of the invention [0004] Embodiments of the present application provide an automobile, a motor, and an energy conversion device to solve the technical problem that the power u...
