Abstract

The invention discloses a permanent magnet coupling speed regulator. The speed regulator comprises a cylindrical conductor rotor, a cylindrical magnetic isolation housing, a cylindrical permanent magnet rotor and a regulator, wherein the cylindrical magnetic isolation housing is positioned between the cylindrical conductor rotor and the cylindrical permanent magnet rotor; gaps are reserved between the cylindrical magnetic isolation housing and the cylindrical conductor rotor and between the cylindrical magnetic isolation housing and the cylindrical permanent magnet rotor; the cylindrical conductor rotor and the cylindrical permanent magnet rotor independently rotate around rotation axes of the cylindrical conductor rotor and the cylindrical permanent magnet rotor respectively and the axial positions are not changed; and under the action of the regulator, the cylindrical magnetic isolation housing slides along the axial direction, so that the area of an acting magnetic field between the cylindrical permanent magnet rotor and the cylindrical conductor rotor is changed; therefore, load torque and rotation speed are changed.

Description

technical field [0001] The invention relates to a speed regulating device, in particular to a permanent magnetic coupling speed regulating device. Background technique [0002] The invention patent with the patent number 200910232125.6 discloses a permanent magnet governor. It includes: a cylindrical conductor rotor, a cylindrical permanent magnet rotor and a regulator, which is characterized in that: the cylindrical permanent magnet rotor is in the cylindrical conductor rotor, separated by an air gap, and rotates independently with the respective rotating shafts installed; The device adjusts the relative position of the cylindrical permanent magnet rotor and the cylindrical conductor rotor in the axial direction, so as to change the interaction area between the cylindrical conductor rotor and the cylindrical permanent magnet rotor, and realize the change of the relationship between the cylindrical conductor rotor and the cylindrical permanent magnet rotor. The size of the ...
