Problems solved by technology

Dampers and valves are traditional methods, which can effectively adjust the flow or pressure, but the disadvantages are also obvious: no energy saving, easy to cause impact in the system, and loud noise
Although the hydraulic governor can adjust the speed and save energy to a certain extent, its efficiency is low and it is not stable enough
Inverter and internal feedback chopper speed regulation use the method of directly changing the motor speed to adjust the system and load. The efficiency is high and the energy saving effect is good. Short, with electromagnetic interference, high maintenance costs

Abstract

The invention discloses a disk-type permanent magnetic speed regulator. The disk-type permanent magnetic speed regulator comprises a first shaft and a second shaft which are coaxially arranged in a split mode. The end of the first shaft is connected with sliding blocks and conductor disks through a speed regulation mechanism. The conductor disks are made of materials with good conductivity. The end of the second shaft is connected with a permanent magnetic rotary disk through a load connecting disk. Permanent magnets are mounted on the permanent magnetic rotary disk and are arranged between the conductor disks. According to the disk-type permanent magnetic speed regulator, the structure of a permanent magnetic rotor is simplified, and the disk-type permanent magnetic speed regulator is only provided with one permanent magnetic rotary disk, so that the weight of the permanent magnetic rotor is greatly reduced on the basis of achieving air gap regulation, and the permanent magnetic rotor is more stable in the rotating process; consequently, mechanical friction and mechanical abrasion are reduced, interference of vibration is avoided, loss of transmission components is reduced, vibration is isolated, and noise is lowered; meanwhile, the disk-type permanent magnetic speed regulator is easy to install and debug, free of precise centering, capable of allowing a certain axial movement, and capable of changing output rotating speed and achieving the purposes of speed regulation and energy conservation through the design of two kinds of speed regulation mechanisms, and the size of air gaps can be controlled more accurately.

Description

technical field [0001] The invention relates to a permanent magnet speed regulating device, in particular to a permanent magnet speed regulating device which achieves the purpose of speed regulation and energy saving by adjusting the air gap between a permanent magnet rotor and a conductor rotor. Background technique [0002] Existing motor systems, especially centrifugal equipment systems, mainly use the following methods to regulate flow and pressure: damper baffles, valves, hydraulic governors, frequency converters, and internal feedback chopper speed regulation. Dampers and valves are traditional methods that can effectively adjust flow or pressure, but the disadvantages are also obvious: they are not energy-saving, easily cause shocks in the system, and cause high noise. Although the hydraulic governor can adjust the speed and save energy to a certain extent, its efficiency is low and it is not stable enough. Inverter and internal feedback chopper speed regulation use ...
