Abstract

The invention relates to a permanent magnet speed regulator with a fixed magnetic gap. The permanent magnet speed regulator comprises a magnetic rotor disc connected with an input shaft, an armature rotor disc arranged on the opposite surface of the magnetic rotor disc and connected with an output shaft, and an armature stator arranged on the back surface of the magnetic rotor disc; the magnetic rotor disc comprises a permanent magnet B and a permanent magnet A arranged on the inner and outer side surfaces of the outer circumference thereof respectively; a winding coil B is arranged on the inner side surface of the outer circumference of the armature rotor disc; the armature stator comprises a fixed base and a winding coil A distributed in the inner side circumferential direction of the circumference of the fixed base; a control system is arranged between the winding coil B and the winding coil A; and a slip ring is mounted on the armature rotor disc. By adoption of a slip frequency energy rectifying and feedback technology, quick boosting or braking can be realized through the winding coil A, so that the permanent magnet speed regulator with the fixed magnetic gap is quick in response, flexible and stable; and by virtue of the slip frequency energy rectifying and feedback boosting effect, maximum of the speed regulating efficiency is realized consequently.

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. ...
