Powertrain, method for controlling cooling of powertrain, and vehicle

A motor, a powertrain, and a device. A plurality of first oil channels are formed between an inner surface of a housing and an outer surface of a stator core, second oil channels are formed at groove roots of coil slots of the stator core, to form double-layer oil channels at the outer surface of the stator core and the root of the coil slot of the stator core, and ensure effective cooling of the stator core and a coil winding. After cooling oil is injected from an oil filling port, a flow direction of the cooling oil in some of the second oil channels is opposite to that of cooling oil in a remaining second oil channel, so that interleaved reverse flows are implemented, and axial temperature of the stator core and the coil winding is more even.

An oil inlet of a motor communicates with a first end of an oil pump through a first passage. A first oil sump of the motor communicates with a second end of the oil pump through a second passage. When the oil pump is rotating, a port at the first end is an oil outlet of the oil pump, and a port at the second end is an oil inlet of the oil pump. The first end of the oil pump communicates with a second oil sump through a third passage with a first valve. The second end of the oil pump communicates with the second oil sump through a fourth passage with a second valve. In this way, when the oil pump is reversing, coolant may be input into a motor cavity and accumulate in the motor cavity, so as to cool motor components in an immersion manner.
