Currently the renewable energy presents an increasing interest and special attention is given to the small scale wind turbines, used to generate electricity for domestic needs. Their purpose is to produce electric energy at increasingly smaller speeds of the wind and with improved economically efficiency. This paper presents the design and study of the behavior for a direct drive permanent magnet...
The gearless PM generator system has high potential for the wind turbines because of its robustness, increased energy yield and reliability compared to electrically excited ones. The main disadvantage of PM synchronous generators is the high cost of PMs and the demagnetization risk at high temperature. In this paper is presented a comparative analysis in terms of permanent magnet type chosen for the...
