Abstract

A permanent magnetic coupling device includes an conductor rotor, an permanent magnet rotor and permanent magnets. The permanent magnet rotor includes a magnetic ring. The magnetic ring includes protrusions and recesses arranged alternately, in which first airflow channels are formed between the protrusions and the conductor rotor respectively, and second airflow channels are formed between the recesses and the conductor rotor respectively. A cross-sectional area of each of the second airflow channels is greater than a cross-sectional area of each of the first airflow channels. The permanent magnet rotor further includes cavities disposed at the recesses, and the permanent magnets are engaged into the cavities respectively.

Description

Technical field [0001] The invention relates to a permanent magnet speed-regulating coupling. Background technique [0002] Permanent Magnetic Coupling Device (Permanent Magnetic Coupling Device) is a transmission device that transmits torque through an air gap. The existing Permanent Magnetic Coupling Device is mainly composed of a conductor rotor and a permanent magnet rotor. The conductor rotor is fixed on the driving shaft and connected to the motor end; the permanent magnet rotor is fixed on the load shaft and connected to the load. There is a gap between the conductor rotor and the permanent magnet rotor. In this way, the connection between the motor and the load will change from the original mechanical connection to a magnetic connection. By adjusting the air gap distance or area between the permanent magnet rotor and the conductor rotor, the output torque on the load shaft can be changed, thereby adjusting the load speed. [0003] The permanent magnet variable speed coup...
