A permanent magnet speed governor that can change the direction of rotation

Abstract

The invention relates to a permanent magnet speed governor capable of changing the direction of rotation, which includes a first outer rotor connected to an input shaft, a second outer rotor connected to the first outer rotor through a reversing gear, and a first outer rotor concentrically passed through the output shaft. The permanent magnet rotor and the second permanent magnet rotor, the first permanent magnet rotor and the second permanent magnet rotor are respectively distributed with at least one first permanent magnet and second permanent magnet along the circumferential direction of their respective outer circumferential surfaces and there are mutual lock device; the first outer rotor and the second outer rotor are respectively distributed with first conductors and second conductors along the circumferential direction of their respective inner circumferential surfaces; the first permanent magnet rotor and the second permanent magnet rotor are respectively provided with Drive the first actuator and the second actuator to move along the length direction of the output shaft. The invention installs the reversing gear on the outer rotor, so that the output shaft can adjust the steering conveniently and quickly, avoiding the problem of needing to input a large power to obtain the required torque when starting at low speed, improving the torque transmission capacity and reducing the difficulty of assembly.

Description

Technical field [0001] The invention relates to a permanent magnet speed governor, in particular to a permanent magnet speed governor capable of changing steering. Background technique [0002] The permanent magnet governor is through the magnetic coupling of permanent magnets to realize the soft (magnetic) connection between the motor and the load, without any harmonic generation that affects the grid, and has high reliability. It can be used in high temperature, low temperature, humidity, and dirty conditions. , Inflammable, explosive, unstable voltage, lightning and other harsh environments, greatly reducing mechanical vibration, widely used in electric power, steel, metallurgy, petrochemical, papermaking, municipal administration, ships, irrigation and mining industries. Three patent documents with patent numbers 201420174225.4, 201420554495.8, and 201420755016.9 respectively disclose three types of permanent magnet rotors with adjustable magnetic force, which can realize tor...

AI Technical Summary

Problems solved by technology

At present, the output direction of the commonly used permanent magnet governor is the same as the input direction. When starting at low speed, a large power input is required to obtain the required torque, resulting in energy waste.
