大间隙磁力传动系统驱动磁场的产生方法研究
Generating methods of driving magnetic field for the large gap magnetic driving system
摘要
Abstract
Two generating methods of driving magnetic field were presented for the large gap mag netic driving system driving permanent magnet axial-flow blood pump, using single pole and double pole switching mode. The coupling mechanism of magnetic field and driving torque of the system driven by the two kinds of magnetic field was simulated and compared based on ANSYS software. Using the mathematical model of energy transfer efficiency and electromagnet-loss, the energy transfer efficiency of magnetic driving part and loss of the electromagnets driven by the two kind of magnetic field was calculated and compared through experiments of the blood pump.The results show that both of the two methods can drive permanent magnet rotating smoothly in high-frequency and high speed situation, and using double pole switching mode as the generating method of driving magnetic field for the system according to the comparison.关键词
