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.
