Abstract

A permanent-magnet speed governor with a fixed magnetic gap includes an outer rotor connected to an input shaft; an outer magnetic stator disposed on the outer side of the circumference of the outer rotor; and an inner armature rotor connected to an output shaft and disposed on the inner side of the circumference of the outer rotor. The outer rotor includes an iron core, a permanent magnet B distributed circumferentially along the inner circumferential surface of the iron core, and a winding coil A distributed circumferentially along the outer circumferential surface of the iron core. A winding coil B is distributed circumferentially along the outer circumferential surface of the inner armature rotor. The outer magnetic stator includes a fixed seat on the outer side of the circumference ofthe outer rotor and a permanent magnet A distributed circumferentially along the inner circumferential surface of the fixed seat. A control system is connected between the winding coil B and the winding coil A. The outer rotor and the inner armature rotor are both equipped with slip rings. The permanent-magnet speed governor uses a slip energy rectification feedback technology and realizes rapidboosting or braking through the winding coil A so as to be fast, flexible and stable in speed regulation response. The slip energy rectification feedback boosting effect achieves maximum speed governing efficiency.

Description

technical field [0001] The invention relates to a governor, in particular to a permanent magnet governor with a fixed magnetic gap. Background technique [0002] The permanent magnet speed governor uses the magnetic coupling speed of the permanent magnet to realize the soft (magnetic) connection between the motor and the load, without any harmonic generation affecting the power grid, and has high reliability. , Inflammable and explosive, voltage instability and lightning and other harsh environments, greatly reducing mechanical vibration, widely used in electric power, steel, metallurgy, petrochemical, papermaking, municipal, ships, irrigation and mining industries. At present, the commonly used permanent magnet governors realize the speed adjustment by adjusting the air gap. The magnetic circuit regulator consumes a lot of power, and has disadvantages such as poor torque transmission capability, high assembly difficulty, and waste of a large amount of rare earth resources. ...
