Abstract: 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.

Abstract: Embodiments of this application provide a heating control method and apparatus, an oil pump, and a heat exchange system. The method includes: in a cold state, injecting a heating current into an oil pump motor, where when the oil pump motor is not started, a torque that the heating current is capable of generating is zero, and after the oil pump motor is started, heating power of the heating current is greater than heating power of an energy-saving current, where the energy-saving current is a current capable of enabling a first motor to reach a target operating condition when oil temperature is greater than a preset temperature threshold.
