Abstract

The invention relates to a permanent magnet speed regulator of a fixed magnetic gap. The speed regulator comprises a magnet rotor, an outer armature stator and an inner armature rotor, wherein the magnet rotor is connected to an input shaft; the outer armature stator is located in a circumferential outer side of the magnet rotor; and the inner armature rotor is connected to an output shaft and islocated in a circumferential inner side of the magnet rotor. The magnet rotor comprises permanent magnets B which are circumferentially distributed along an inner circular surface and permanent magnets A which are circumferentially distributed along an outer circular surface. Winding coils B are circumferentially distributed along an outer circular surface of the inner armature rotor. The outer armature stator comprises a fixed seat and winding coils A, wherein the fixed seat is located at an outer side of a circumference of the magnet rotor; and the winding coils A are circumferentially distributed along an inner circular surface of the fixed seat. A control system is connected between the winding coils B and the winding coils A. The inner armature rotor is equipped with a slip ring. In the invention, a slip energy rectification feedback technology is adopted; through the winding coils A, rapid boost or brake is realized so that speed regulation reaction of the speed regulator of thefixed magnetic gap is rapid, flexible and stable; and through a slip energy rectification feedback boost effect, maximization of speed regulation efficiency is realized.

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. ...
