Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a high-efficiency air-cooled rotor. Background Art

[0002] At present, motor heat dissipation is a key technical topic. If the motor cannot dissipate heat effectively during operation, its service life will be greatly reduced. Especially for asynchronous motors, high-temperature rotors will cause the motor rotor winding resistance to increase, thereby increasing the motor rotor excitation loss and reducing motor efficiency; for permanent magnet synchronous motors, high-temperature rotors will cause the magnetic properties of the motor magnets to decrease, and even directly lead to magnet demagnetization, which is a fatal threat to permanent magnet motors.

[0003] At present, some motors at home and abroad use an open heat dissipation method. Through the hollow structure of the motor, the surface airflow is allowed to flow during the rotation of the rotor to dissipate heat. This heat dissipation method results in a low air flow effect on the rotor surface and cannot solve the heat dissipation problem of the motor well. Another method is to add a turbine or fan blade at the end of the rotor to speed up the circulation of air around the rotor, but the heat accumulated inside the rotor is still difficult to dissipate. In view of this, the existing problems are studied and improved, and a high-efficiency air-cooled rotor is provided to solve the current problems. The purpose is to solve the problems and improve the practical value through this technology. Utility Model Content
