Abstract :
A novel field modulated magnetic gear (FMMG) with concentric configuration is proposed and introduced to the drive train for a wind turbine system, which eliminates the vibration, noise and lubrication problems of mechanical gearbox and avoids the size and weight issues of directly-driven wind turbines The efficiency and reliability are improved simultaneously. Based on the static field computations by finite element analysis, the dynamic model of synchronous generator and magnetic gear is established and the dynamic performance of the transmission system is studied. The electromagnetic design and simulation results are verified by the experiment of the 1kW FMMG prototype with gear ratio of 6.75:1.
