Abstract: The development of permanent magnet technology was introduced in the field of wind power generation and the relevant requirements of high reliable permanent magnet of wind turbine. The factors affecting the long-term reliability of permanent magnet were analyzed.The mechanism was expounded to ensure the long-term reliability of permanent magnet wind turbine from the perspectives of magnetic pole fixation, magnetic pole protection and magnet stability. In order to cope with the parity market competition in the wind power market, the optimization design direction of permanent magnet was given.

Key words: permanent magnet motor, direct drive, semi-direct drive, wind power generator
