Study on Energy Loss Model of Large Gap Magnetic Drive System

In order to research the energy transfer law in large gap magnetic drive system under the condition of large gap and high speed, the large gap magnetic drive technology, which is driven by traveling wave magnetic field, is studied. Based on the outside magnetic driving system of axial flow blood pump, the mathematical and experimental model of energy loss is established through studying on each several part of the system. Then the energy transfer efficiency of system and its change tendency and influential factors are got out by analysis and experiments to lay a foundation for the further research of energy transfer law in large gap magnetic drive system.
