Description

Technical Field

[0001] The invention relates to the technical field of permanent magnet motor heat dissipation, and in particular to a double-effect heat dissipation type permanent magnet motor. Background Art

[0002] The permanent magnet motor uses permanent magnets as magnetic poles on its rotor. Through the principle of electromagnetic induction, it interacts with the current in the coil on the stator, causing the motor to generate torque, thereby realizing bearing rotation. It mainly adjusts the motor speed by changing the power supply frequency, voltage or using a speed change mechanism. The dual-effect motor usually consists of an electric motor, but two different working states are achieved by changing the circuit or mechanical structure. Most of the losses generated by the permanent magnet motor during the electromechanical energy conversion process are converted into heat, which causes the temperature of the motor components to rise. The temperature rise has a serious impact on the motor life and operating reliability.

[0003] Existing permanent magnet motors tend to generate a lot of heat when in use, and often use cooling fans to cool them down. Some even knock on the motor to remove dust from it to improve the heat dissipation efficiency. Both have low heat dissipation effects, and knocking can easily damage the circuits and components inside the motor. For this reason, we design a dual-effect heat dissipation permanent magnet motor.
