A liquid-cooled core assembly for a linear motor includes an iron-core having a middle part, teeth extending from two opposite sides of the middle part and forming slots therebetween, coils wound around the teeth, axial cooling-fluid passageways extending across the middle part, and cooling conduits mounted inside the passageways. The core assembly further includes a cooling arrangement having a liquid supply part and a liquid collection part mounted against respective two other opposite sides of the iron-core. The liquid supply and collection parts are in fluid communications with the cooling conduits. An inlet connector is in fluid communication with the liquid supply part, and an outlet connector is in fluid communication with the liquid collection part.

A motor unit includes a motor including a rotor, a stator radially outside of the rotor; a housing for housing the motor; an oil passage for circulating the oil in the housing space; and a gear portion connected to a shaft of the rotor. The housing includes a motor housing portion defining a motor chamber in an interior, a gear housing portion defining a gear chamber in an interior, and a partition dividing the gear chamber and the motor chamber. The oil passage includes a flow passage arranged in an interior of the housing, and an oil feeding structure on an upper side of the motor to feed the oil to at least one of a stator core or coil ends. The flow passage includes a portion extending along an axial direction to feed the oil to the oil feeding structure. The partition includes the portion of the flow passage.

A motor, a powertrain, and a vehicle. The motor may be applied to an electric motor vehicle/electric vehicle, a pure electric vehicle, a hybrid electric vehicle, a range extended electric vehicle, a plug-in hybrid electric vehicle, a new energy vehicle, battery management, a motor & driver, a power converter, a reducer, or the like. The motor is configured to output power. In a process of outputting power by the motor, a blocking member arranged in the motor blocks the contact between a rotor of the motor and a coolant, so that the coolant does not splash under the centrifugal action of the rotor in the process of rotation, thereby avoiding the kinetic energy consumption of the rotor. Therefore, a rotating speed of the motor is faster, and the output power is greater.
