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 magnetic speed regulator with a fixed magnetic gap. The speed regulator comprises a rotor connected with an input shaft, an armature rotor and a magnetic rotor. The armature rotor and the magnetic rotor are connected with an output shaft and arranged on the inner side and the outer side of the circumference of a rotor respectively. The rotor comprises permanentmagnets A which are circumferentially distributed along the inner circumferential face of the rotor, and winding coils B which are circumferentially distributed along the outer circumferential face of the rotor. The armature rotor comprises winding coils A which are circumferentially distributed along the outer circumferential face of the armature rotor. The winding coils B and the winding coilsA are serially connected in a same-polarity manner. A control system is serially connected between the winding coils B and the winding coils A. Sliding rings are installed on the rotor and the armature rotor. According to the invention, by use of the armature rotor, heating loss of the rotor can be greatly reduced; by use of the current control principle, rapid, flexible and stable speed regulation reactions of the speed regulator can be achieved; transmission efficiency of the speed regulator is greatly improved; and application range is quite wide.

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. ...
