A permanent magnet speed governor having a fixed magnetic gap. The permanent magnet speed governor comprises an outer conductor rotor (2), a first inner magnetic rotor (4) and a second inner magnetic rotor (9), a conductor (3) being distributed along the circumferential direction of the inner circumferential surface of the outer conductor rotor. At least one first inner permanent magnet (6) and at least one second inner permanent magnet (8) are respectively and evenly distributed along the circumferential direction of the outer circumferential surface of the first inner magnetic rotor and the second inner magnetic rotor, the magnetic poles of the inner permanent magnets on each inner magnetic rotor being arranged along the circumferential direction, the magnetic poles of adjacent sides of two adjacent inner permanent magnets on a same inner magnetic rotor being different. The speed governor reduces the difficulty of assembly, reduces the consumption of materials and saves installation space.
Description
technical field [0001] The invention relates to a permanent magnet 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 ...
