The Experience of Designing and Testing 20 kW Multipole Permanent Magnet Generator for Wind Turbines

摘要

1. Designed permanent magnet generator (PMG - 20 kW) possesses a number of advantages: 1.it may operate as a selfcon-tained stand alone system; 2.it replaces the gearbox, the generator and possibly the hub of the wind turbine by combining wind rotor with external rotor of the generator; 3.the use of the PMG for wind-turbines increases the reliability of the construction during the life time as compared to the conventional design (gearbox, asynchronous generator).
