A motor stator, in which a flux winding is bent into a wave shape, and may be divided into a plurality of first parts, a plurality of second parts, and a plurality of third parts based on winding positions on a stator core. In a process of embedding flux windings into stator slots on the stator core, the flux windings may be directly sunk into the stator slots one by one, so that the second part is embedded into the stator slot, the first part is located on an outer surface of the stator core, and the third part is located on an inner surface of the stator core. It is quite easy to wind the flux windings on the stator core, so that a problem of difficult tapeout caused by a small volume of the motor stator is resolved.
