Abstract

The invention relates to a fixed-magnetic gap permanent-magnet speed regulator. The fixed-magnetic gap permanent-magnet speed regulator comprises an armature rotor, a magnetic stator and an inner rotor, wherein the armature rotor is connected with an input shaft, the magnetic stator is arranged at a tail end of the armature rotor, the magnetic stator and the armature rotor are arranged in parallel, the inner rotor is connected with an output shaft and is arranged at circumferential inner sides of the armature rotor and the magnetic stator, the armature rotor comprises an iron core and windingcoils B, the winding coils B are circumferentially arranged along an inner circumferential surface of the iron core, the magnetic stator comprises a fixed seat and permanent magnets A, the permanent magnets A are circumferentially arranged along an inner circumferential surface of the fixed seat, permanent magnets B and winding coils A are arranged in parallel along an outer circumferential surface of the inner rotor, a control system is connected between the winding coils B and the winding coils A and is used for converting electric energy, and sliding rings are arranged at the armature rotorand the inner rotor. A slip frequency energy rectification feedback technology is employed, rapid boosting or braking is achieved by the winding coil A, so that the fixed-magnetic gap speed regulatoris rapid, flexible and stable in speed regulation response; and by a slip frequency energy rectification feedback boosting effect, maximum speed regulation efficiency is achieved.

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. ...
