A cooling unit of a drive motor includes: a fixing member installed on an inner wall surface of a motor housing and configured to fix a stator core of the drive motor, wherein the fixing member has a ring shape, includes a flow path formed therein in order to allow a cooling medium to flow, and includes a cooling medium inlet and a cooling medium outlet formed to be connected to the flow path, the flow path includes a first path connecting the cooling medium inlet and the cooling medium outlet to each other at one side and a second path connecting the cooling medium inlet and the cooling medium outlet to each other at another side, and the first and second paths have different flow cross sections and are connected to each other.

Cooling unit of drive motor

A system and a method of controlling a drive motor for a vehicle is disclosed. The system of controlling a drive motor for a vehicle may include: an engine and the drive motor as power sources; a data detector detecting a state data for controlling the drive motor; and a vehicle controller setting a motor demand power and a gear stage based on the state data. In particular, the vehicle controller generates a motor demand torque based on the motor demand power and the gear stage, checks a motor temperature after driving the drive motor based on the motor demand torque, and changes the gear stage based on the motor temperature.

System and method of controlling drive motor for vehicle

A motor having a cooling structure includes: a motor shaft in which a cooling passage is formed in a center thereof in a lengthwise direction; a rotor disposed at an exterior circumference of the motor shaft to rotate together with the motor shaft; and a motor housing in which a stator fixed at a predetermined interval from the rotor is disposed at an interior circumference thereof and in which the motor shaft is disposed to be rotatable, wherein a coolant flowing through the cooling passage is jetted to the rotor or the stator.

Motor having cooling structure

A connector for connecting a motor is provided. The connector for connecting a motor for electrically connecting a three phase coil connecting portion that is drawn out from a motor and a three phase power terminal that is connected with a power cable includes: i) a under terminal block that houses the each power terminal and the each coil connecting portion; ii) an upper terminal block that is coupled to the under terminal block and that presses the each power terminal and the each coil connecting portion; and iii) an engagement portion that engages the under terminal block and the upper terminal block.
