Optimal design and analysis of a new type of eddy-current driver

Eddy current of the eddy-current driver could reduce transmission efficiency because its thermal losses. Faced with these questions, this paper gave an analysis for the new structure by means of the finite element emulation software at first. Then Based on the principle of motor, this paper improved the structure of eddy-current driver according to the result of analysis. A new type of eddy-current driver with 72-slotted conductor plate filled with steel blocks is invented. The simulation result shown that the current flows mainly along radial path, which increases dragging force among magnetic fields and driving torque. After made a 15 KW model machine, an experiment was taken to validate it as well. The results indicated that improvement effect of torque and efficiency of this new type of eddy-current driver are considerable. It gave important references of high-power and optimization of the eddy-current driver.
