Problems solved by technology

Due to the use of the eddy current induction principle, the energy conversion efficiency is low, the heat generation is large, and a large amount of heat is generated during slippage
Using magnetic circuit adjustment system, the adjustment speed is slow and the response is not sensitive

Abstract

The invention relates to a permanent magnet speed regulator with a fixed magnetic gap. The permanent magnet speed regulator comprises an inner rotor disc connected with an input shaft, and an armaturerotor disc and a magnetic rotor disc arranged on the two side surfaces of the inner rotor disc and connected with an output shaft; the inner rotor disc comprises a winding coil B and a permanent magnet A arranged on the inner and outer side surfaces of the outer circumference thereof; a winding coil A is arranged on the inner side surface of the armature rotor disc; a permanent magnet B is arranged on the inner side surface of the magnetic rotor disc; the winding coil B and the winding coil A are connected in series at the same polarity, and a control system used for current regulation is connected in series between the two winding coils; and slip rings are mounted on the inner rotor disc and the armature rotor disc respectively. By adoption of the armature winding, rotor heating loss canbe greatly lowered; and by adopting a current control principle, quick response, flexibility and stability of the speed regulator can be realized, thereby greatly improving the transfer efficiency ofthe permanent magnet speed regulator with the structure and achieving a wider application range.

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. ...
