Abstract

The invention relates to a magnetic-gap-fixed permanent magnet speed regulator comprising an external rotor which is connected with an input shaft, an external armature stator which is arranged on theexternal side of the circumference of the external rotor and an internal magnet rotor which is connected with an output shaft and arranged on the internal side of the circumference of the external rotor. The external rotor comprises an iron core, winding coils B which are circumferentially distributed along the internal circumferential surface of the iron core and permanent magnets A which are circumferentially distributed along the external circumferential surface of the iron core. Permanent magnets B are circumferentially distributed along the external circumferential surface of the internal magnet rotor. The external armature stator comprises a fixing base which is arranged on the external side of the circumference of the external rotor and winding coils A which are circumferentially distributed along the internal circumferential surface of the fixing base. A control system used for electric energy conversion is connected between the winding coils B and the winding coils A. A slipring is installed on the external rotor. The slip energy rectification feedback technology is used, and rapid boosting or braking can be realized through the winding coils A so that the speed regulation response of the magnetic-gap-fixed speed regulator is enabled to be rapid, flexible and stable and maximization of the speed regulation efficiency can be realized through the effect of slip energyrectification feedback boosting.

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. ...
