Double-layer standard squirrel cage conductor rotor high torque density permanent magnetic speed controller

Abstract

The invention discloses a double-layer standard squirrel cage conductor rotor high torque density permanent magnetic speed controller. The permanent magnetic speed controller comprises an input shaftand an output shaft set on the same central axis, wherein the input shaft is provided with a conductor rotor in a penetration mode, the output shaft is provided with a first permanent magnet rotor anda second permanent magnet rotor in a penetration mode, the first permanent magnet rotor and the second permanent magnet rotor can rotate with relative concentricity, the first permanent magnet rotor,the conductor rotor and the second permanent magnet rotor are sequentially concentrically sleeved in the radial direction, a first air gap is between the first permanent magnet rotor and the conductor rotor, and a second air gap is between the conductor rotor and the second permanent magnet rotor. The permanent magnetic speed controller is advantaged in that through rotation of the first permanent magnet rotor or the second permanent magnet rotor, the relative rotation angle between the first permanent magnet rotor and the second permanent magnet rotor is changed, the speed control function of the speed controller is achieved, in the speed control process, overcoming the cogging torque is only required, the function of the speed controller is different from the speed control function achieved through adjusting an axial air gap between a magnetic rotor and a conductor rotor in the prior art, and axial length of the permanent magnetic speed controller is effectively reduced.

Description

technical field

[0001] The invention relates to a permanent magnet governor, in particular to a double-layer standard squirrel cage conductor rotor high torque density permanent magnet governor. Background technique

[0002] With the promotion and application of high-performance permanent magnet materials, the permanent magnet speed control technology, which has developed rapidly, is a new type of speed control and energy-saving technology for motor drive systems applied between the prime mover and the load. The speed-regulating permanent magnet coupler has a good energy-saving effect, reduces operating costs, and can also realize the soft start and soft stop functions of the motor. It can operate in harsh environments such as flammable, explosive, humid, and high dust content, and it is a mechanical structure that can adapt to situations such as unstable power grid quality and impact loads caused by current changes. Mainly used in the chemical industry, petrochemical indus...
