PERMANENT MAGNET SPEED GOVERNOR WITH FIXED MAGNETIC GAP

Title:

PERMANENT MAGNET SPEED GOVERNOR WITH FIXED MAGNETIC GAP

Document Type and Number:

WIPO Patent Application WO/2015/154408

Kind Code:

A1

Abstract:

A permanent magnet speed governor with a fixed magnetic gap, comprising a barrel-shaped conductor rotor (1) and a permanent magnet rotor therein, wherein the permanent magnet rotor comprises a driven shaft (7) and at least one rotatable permanent magnet (4) circumferentially arranged around the driven shaft, the rotatable permanent magnet is cylindrical and has an N pole and an S pole in the diameter direction, magnetic conductors (2) are wrapped at the two sides of the rotatable permanent magnet, the two magnetic conductors are separated by a non-magnetic conductor (10), the rotatable permanent magnet is connected to the driven shaft by the magnetic conductor at one side, and a magnetic circuit regulator is arranged at one end of the rotatable permanent magnet. Since a fixed magnetic gap structure is adopted, the engagement area of the speed governor is increased, and the assembling difficulty is reduced, thereby reducing the waste of rare earth materials and increasing the torque transmission capability. In addition, the power consumption of a mechanism for executing adjustment is reduced and the entire volume of the speed governor is reduced, and convenience is brought to the site installation construction at the same time.
