Analysis of position response characteristics of magnetic driven oil-free scroll compressor
Traditional scroll compressors are difficult to achieve oil-free operation due to the presence of a high-friction anti-rotation mechanism. This paper proposes a magnetic drive oil-free scroll compressor to solve this problem. Firstly, the structure and principle of this scroll compressor are introduced. Then the finite element analysis of the electromagnetic system was conducted; the dynamics model of the magnetic scroll compressor operating in the uncompressed state was established. Finally, the PID control of the system is performed, and simulations and experiments are carried out. Experimental results: under the 0.05 mm step signal in the X direction, the position response time of the system is 0.1 s, and the angle response time of 0.001 rad is 0.2 s. The results show that the oil-free scroll compressor has good position control response characteristics.
期刊介绍:
The aim of the International Journal of Applied Electromagnetics and Mechanics is to contribute to intersciences coupling applied electromagnetics, mechanics and materials. The journal also intends to stimulate the further development of current technology in industry. The main subjects covered by the journal are:
Physics and mechanics of electromagnetic materials and devices
Computational electromagnetics in materials and devices
Applications of electromagnetic fields and materials
The three interrelated key subjects – electromagnetics, mechanics and materials - include the following aspects: electromagnetic NDE, electromagnetic machines and devices, electromagnetic materials and structures, electromagnetic fluids, magnetoelastic effects and magnetosolid mechanics, magnetic levitations, electromagnetic propulsion, bioelectromagnetics, and inverse problems in electromagnetics.
The editorial policy is to combine information and experience from both the latest high technology fields and as well as the well-established technologies within applied electromagnetics.
