Problems solved by technology

At the same time, when building the AMB and its rotor system, designers need to manually design specific control parameters for each specific rotor, not only need to consider the design of the control system, but also consider the sensor structure and its performance indicators, mechanical structure and Multi-disciplinary problems such as accuracy level, rotor dynamics analysis, etc., the process is complex and cumbersome
Therefore, problems such as high professionalism, low efficiency, high labor intensity, and high cost have long been the bottleneck problems in AMB design

Embodiment Construction

[0030] A preferred embodiment of the present invention is described as follows in conjunction with accompanying drawing:

[0031] Fig. 1 is a block diagram of the working principle of the five-degree-of-freedom magnetic suspension bearing system implemented in the present invention, which includes a digital controller, a five-degree-of-freedom power amplifier integrated system module, a five-degree-of-freedom sensor conversion module, 2 radial electromagnetic bearings, 1 An axial magnetic bearing and a rotor. The rotor is the controlled object in the whole system. The sensor detects the movement position of the suspended rotor and feeds the signal back to the digital controller. The controller generates corresponding control signals according to the feedback signals, and then the power amplifier converts the control signals into corresponding control signals. Voltage or current actively controls the electromagnet in the actuator, that is, the electromagnetic bearing, so that t...

Abstract

The smart magnetic bearing comprises an electric magnetic bearing whose one end is provided with a smart component and end cap. In the smart component there is a sensor circuit which can automatically collect rotor dynamic parameters which are processed and then sent to an external special digital controller, and a general series bus USB storage apparatus circuit for storing electromagnetic bearing inherent parameters which are called and renewed by the external special digital controller so as to make the controller automatically control electromagnetic bearing.

Description

technical field [0001] The invention relates to an electromagnetic suspension bearing. In particular, it is an intelligent magnetic bearing that can adapt to future machinery, with multidisciplinary knowledge such as electronics, electromagnetism, control science, sensor science, and computer science as its theoretical and technical background, and is suitable for general or special mechanical equipment. . Background technique [0002] At present, as a high-performance support component recognized in the world, electromagnetic bearings have technical indicators and incomparable performance characteristics that cannot be achieved by traditional mechanical support technologies. In foreign countries, electromagnetic bearings have been successfully applied to various rotating machinery and reciprocating machinery in many industrial fields (such as machining, nuclear energy, chemical industry, aerospace, food and medicine, etc.). However, due to the particularity of the design ...
