Design and performance comparison of large clearance magnetic transmission system

For the sake of enhancing the reliability of magnetic transmission under the condition of high rotary speed, the large clearance magnetic transmission technology with traveling wave mag-netic field drive has been studied. On the basis of analyzing the ki-nematic states between the system driving magnetic pole ( electro-magnet) and the driven magnetic pole (permanent magnet), the re-lationship between the switch over method of the electromagnet mag-netic pole status and the kinematic state of permanent magnet in the system was determined, and three kind of driving schemes of the system were put forward. Based on the basic principle of magnetic circuit, through the magnetic field analysis, the establishments of moment transfer calculation model of the system and the experimen-tal study of system spatial magnetic field, the system designing scheme with rather strong driving capability was determined.
