The frame of the stator part of the motor is an important medium for radial heat transfer and heat dissipation of the motor. In the three-phase asynchronous motor, the winding stator core, end cover, bearing system, fan, wind hood, etc., are constructed into a heat exchange system. So what are the parts that affect the temperature rise of the motor? Today, Senli Motor Xiaobian will have a simple understanding with you.

       When the three-phase asynchronous motor is running, the bearing system will heat up to different degrees, which is different from the heating of the stator winding and the rotor part, and there is heat exchange between them. Therefore, if the temperature generated by the winding and rotor part is high, the temperature of the bearing system will rise;

       If the temperature of the bearing system is high due to various adverse factors, it will also lead to an increase in the temperature rise of the motor winding. The bearing system and winding have temperature rise or maximum operating temperature upper limit assessment, if the assessment limit is broken, the bearing system is faced with a large attenuation or collapse of the working life.

       Different motors, the parts that affect the temperature rise are different, for the protective motor, the match of the end cover heat dissipation window and the base heat dissipation window is very critical; For closed motor, the shape and heat dissipation area of the end cover directly affect the bearing system of the motor and the overall heat dissipation effect of the motor; In the winding rotor motor, the temperature rise of the collector ring system will also affect each other with the motor bearing system. For large winding motor collector rings, axial holes will be processed on the collector rings to improve the axial ventilation and heat dissipation effect of the system, and fans will be installed as heat exchange cycle power if necessary.
