大间隙磁力驱动系统空间磁场分布规律研究
Space magnetic field distribution law of large gap magnetic driver system
摘要
Abstract
In order to improve the magnetic drive system' s reliability under the condition of large gap and high speed,the relationship between the magnetic pole state of active magnetic pole (electromagnet) and the running state of passive magnetic pole (permanent magnet) was analyzed,taking the T electromagnet as example.With the software ANSYS,the magnetic induction strength and distribution law of the four states such as NS 、SS、SN and NN were calculated.Through vast experiments,the simulation model of the space magnetic field was proved to be correct and the optimum installation position of the initiative magnetic electromagnet and the permanent electromagnet rotor was found,to provide a foundation for axial flow blood pump to gain the maximal driving torque.关键词
