Abstract

The invention relates to a magnetic gap-fixed permanent-magnet speed regulator. The magnetic gap-fixed permanent-magnet speed regulator comprises a rotor disc, a magnetic rotor disc and an armature stator, wherein the rotor disc is connected with an input shaft, the magnetic rotor disc is arranged on a surface opposite to the rotor disc and is connected with an output shaft, the armature stator isarranged on a back surface of the rotor disc, the rotor disc comprises a winding coil B, a permanent magnet A and an iron core, the winding coil B and the permanent magnet A are respectively arrangedin an outer circumference and on an outer side surface of the rotor disc, the iron core is arranged between the winding coil B and the permanent magnet A, a permanent magnet B is arranged on a side surface of an outer circumference of the magnetic rotor disc, the armature stator comprises a fixed seat and a winding coil A, the winding coil A is arranged along an inner side of the circumferentialsurface of the fixed seat, a control system is connected between the winding coil B and the winding coil A and is used for electric energy conversion, and a sliding ring is arranged on the rotor disc.A slip frequency energy rectification feedback technology is employed, rapid boosting or braking is achieved by the winding coil A, so that the magnetic gap-fixed speed regulator is 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. ...
