Abstract: Design a permanent magnet synchronous generator in this paper. Preliminary designed in equivalent magnetic circuit method, then checked to amend the magnetic circuit method with finite element simulation software MagNet, simulated the performance of the motor model on empty and load working. The result of simulation shows that the design meet the requirements of indicators.
