Abstract

A motor according to an exemplary embodiment of the present disclosure may include first housing installed with a stator and a rotor, a second housing configured to form a refrigerant passage by being distanced from the first housing, when the second housing is coupled to the first housing, a first pipe configured to introduce refrigerant into the refrigerant passage by communicating with the refrigerant passage, and a second pipe configured to discharge the introduced refrigerant, and a plurality of passage lugs configured to be positioned at the refrigerant passage to flow the refrigerant in a zigzag manner.

Description

technical field [0001] An exemplary aspect of the present invention relates to a motor configured to perform a cooling operation using cooling water. Background technique [0002] A motor is an electrical machine that converts electrical energy into mechanical energy (rotational effect) and is widely used as a power source. In a normal motor mode, when the motor produces a rotation effect by consuming electric power, a large amount of heat is generated, and the efficiency of the motor is greatly reduced due to the heat generated by the motor. More recently, water-cooled jackets are used in the case of high-power automotive motors to quickly remove the heat generated by the motor. [0003] A pipe insertion type is widely used for a general water-cooled motor, wherein the pipe insertion type includes a pipe configured to transfer a coolant by passing through the inside of a stator or a case that generates a large amount of heat. However, the conventional pipe insertion type ...
