An air-cooled heat exchange type double-effect heat dissipation motor

Abstract

The invention discloses an air-cooled and heat-exchanging double-effect heat-dissipating motor, which belongs to the field of electric motors. A heat-exchanging air duct is arranged between adjacent heat-dissipating scales. During the operation of the motor body, a rotating shaft drives a turntable and a push block The synchronous rotation can push the curved surface ring plate at intervals to realize the full extension of the heat exchange and air duct and the process of shrinking due to water loss. The fluidity of the surrounding air promotes the heat dissipation on the motor body and the heat dissipation scales, realizes the double cooling of the heat dissipation scales, and then improves the heat dissipation efficiency of the two to the inside of the motor body.

Description

technical field [0001] The invention relates to the field of motors, and more specifically relates to an air-cooled heat exchange type double-effect heat dissipation motor. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. It uses energized coils (that is, stator windings) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric power rotation torque. [0003] When the motor is running continuously, it is prone to overheating. After the temperature continues to rise, the internal resistance of the motor will also increase. At this time, the efficiency and output of the motor will drop sharply, and the higher temperature will also affect the lubrication inside the motor. and insulation, and may even burn out the motor. [0004] In the prior art, heat dissipation scales are usually arranged on the surface of the motor to increase the contact a...

Problems solved by technology

[0003] When the motor is running continuously, it is prone to overheating. After the temperature continues to rise, the internal resistance of the motor will also increase. At this time, the efficiency and output of the motor will drop sharply, and the higher temperature will also affect the lubrication inside the motor. and insulation, it may even burn out the motor

[0004] In the prior art, heat dissipation scales are usually arranged on the surface of the motor to increase the contact area with the air, and the flowing air drives the heat, thereby increasing the heat dissipation efficiency and achieving the effect of heat dissipation. This is air-cooled (air-cooled) heat dissipation, but in the motor In the process of continuous operation, it is far from enough to rely solely on the heat dissipation scales, and it is difficult to achieve a good heat dissipation effect, and there are still great hidden dangers in the stable operation of the motor
