Abstract

The invention discloses a disc water-cooling permanent magnet eddy current speed regulation device which comprises conductor rotators and permanent magnet rotors and is characterized by also comprising an air gap adjustment mechanism and a water-cooling mechanism, wherein the permanent magnet rotors are arranged between the conductor rotators, the air gap adjustment mechanism is connected with the conductor rotators, and the water-cooling mechanism is arranged on the conductor rotators. In the invention, change of the included angle between connecting bars and the up and down sliding of connecting bar shaft pins in a sliding rail are utilized to adjust distance so as to ensure that the distances between two pairs of permanent magnet rotors and conductor rotators interacting with each other are changed equally, and the structure of the speed regulation device is simple, thereby being convenient to process and install; water piloting ribs, the negative pressure principle and the centrifugal force effect are utilized, water can be piloted by a flume to evenly flow past the back iron surfaces of conductors and then thrown away along with the rotation of the conductor rotators from theoutboards of the conductor rotators, and heat quantity is brought away, thus cooling effect can be obtained; and when a main water supply system has faults, a buffer tank is started to continue supplying water until the faults are removed, thus the normal operation of the device can not be influenced by the faults of the water supply system.

Description

technical field [0001] The invention relates to a device used in the field of permanent magnet speed regulation of motors, in particular to a disk-type water-cooled permanent magnet eddy current speed regulation device. Background technique [0002] Permanent magnet speed control technology is a new type of motor speed control and energy-saving technology. It uses high-performance rare earth permanent magnet materials to generate magnetic fields, and adjusts the air gap between the rotating permanent magnets and the metal conductor that generates eddy currents to adjust the magnetic field. Obtain adjustable, controllable and constant load speed, so as to realize load speed adjustment and energy saving. [0003] Working principle: The conductor rotor and the permanent magnet rotor can freely rotate independently. When the conductor rotor rotates, the conductor rotor and the permanent magnet rotor produce relative motion, and the alternating magnetic field generates eddy curre...
