Abstract

The invention discloses a magnet vortex energy saving speed controller. The problems that in the prior art, a speed controlling device is unstable in speed, low in adjusting precision, inconvenient to maintain and large in size are mainly solved. The magnet vortex energy saving speed controller comprises a shell assembly (3), a permanent magnet rotor (2) and a conductor rotor (4), and the permanent magnet rotor (2) and the conductor rotor (4) are arranged in the shell assembly (3) and coupled to each other. A sliding component (5) used for driving the conductor rotor (4) to do axial linear movement is arranged on the conductor rotor (4), and connected with a control component (6) controlling the sliding position of the sliding component (5). The permanent magnet rotor (2) is arranged on the shell assembly (3) through a conical roller bearing, the conductor rotor (4) is arranged on the shell assembly (3) through an involute spline shaft (8), and the involute spline shaft (8) is connected with the shell assembly (3) through a conical roller bearing. The magnet vortex energy saving speed controller has the advantages of being stable, precise and easy and convenient to maintain, saving energy and the like.

Description

Technical field [0001] The invention involves a speed regulator, which is specific to the magnetic vortex energy vessel speed regulator. Background technique [0002] At present, the frequency regulators commonly used in the industry include frequency frequency and speed regulating liquid couplet. [0003] The inverter realizes the motor speed regulation by changing the current frequency of the motor input. The specific method is: the inverter adopts the thorough current input, and the output frequency transformation is achieved through the PWM DC chop.This method will produce a large harmonic current. The harmonic current has severe pollution to the power grid, which can generate a bearing current of the fatal eclipse bearing and accelerate the damage of the bearing.The life of the load is reduced.In addition, the harmonic current will cause the heat loss of the electrical component, and in severe cases, it can cause the equipment error movement; at the same time, the impact loa...
