Title: Challenges in applying permanent magnet technology to wind power generators
Summary:
Most of the world’s top 10 turbine manufacturers have activities in permanent magnet generator (PMG) technolo-gy. The easiest way to switch from traditional double fed induction generators (DFIG) to PMGs is to replace the existing DFIG with the same speed PMG and full-power converter. This requires only minimal design changes of the turbine and nacelle layout.
Permanent magnet (PM) technology offers a variety of concepts, starting from 10 to 20 rpm, large torque, direct-driven generators. It offers various constructional options, like outer rotor and axial-flux generators. PM excitation gives the machines both high efficiency and high torque.
