Abstract

The invention provides an electromagnetic induction energy-saving speed regulator which has simple structure, low cost, high maintenance and long service life and can realize stepless speed regulation. The electromagnetic induction energy-saving speed regulator comprises a driving rotor part which mainly comprises a driving rotor disc, a magnetic inductive steel ring (3) and an induction copper ring (4) and a driven rotor part which essentially comprises a driven rotor disc (7), a permanent magnet (16) and a driven main shaft (11); the speed regulator is characterized in that the magnetic inductive steel ring (7) and the induction copper ring (4) are fixed at the periphery of the driving rotor disc (2) in a barrel shape; the driven rotor disc (7) which is coaxial with the driving rotor disc is connected with the driven main shaft (11) by transmission in the circumferential direction and sliding connection is formed in the axial direction; and the periphery of the driven rotor disc is distributed with the permanent magnet (16) opposite to the induction copper ring (4) in radial direction. The speed regulator also comprises a regulating device used for regulating the axial position of the driven rotor disc opposite to the driven main shaft.

Description

technical field [0001] The invention relates to an electromagnetic induction speed regulating machine. technical background [0002] In the electromagnetic induction speed regulation, so far, there are two commonly used methods: (1) slip motor, the slip motor is composed of two things, an ordinary AC motor, a slip clutch, by adjusting the clutch excitation coil Voltage to adjust the output speed. This kind of motor has a limitation that the maximum speed is the speed of the AC motor. Due to poor speed regulation performance and low efficiency, it is less used now; (2) Frequency converter: Usually, the voltage and frequency A device that converts fixed alternating current into alternating current with variable voltage or frequency is called a "frequency converter". The rotational speed of an induction AC motor depends approximately on the pole number and frequency of the AC motor. Since the number of poles is a multiple of 2, it is not possible to use the number of poles to...
