Description
Technical field [0001] The present application relates to the field of automotive technology, and 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 neutral wire connection method of the star-connected motor winding is relatively simple, and the coil connection method of the motor winding is not flexible, making it difficult to adjust the working power of the motor using the star-connected method. [0003] A new type of motor structure is now being developed to make the adjustment of the motor's working power 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 of difficulty in adjusting the charging...
