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 relates to a governor, in particular to a magnetic eddy current energy-saving governor. Background technique [0002] At present, the commonly used speed regulating devices in the industry include frequency converters and speed regulating hydraulic couplings. [0003] The frequency converter realizes motor speed regulation by changing the current frequency input by the motor. The specific method is: the frequency converter adopts silicon controlled rectification input, and realizes output frequency conversion through PWM DC chopping. This method will generate a large harmonic current, which will seriously pollute the power grid, and can produce fatal electric erosion of the bearing current of the bearing and accelerate bearing damage; at the same time, high-order harmonics will destroy the insulation of the motor, thereby making the motor and load life is reduced. Moreover, the harmonic current will cause heat loss of electrical compone...
