Analysis of starting resistance moment of direct drive wind turbine
Mechanical and Electrical Engineering School, Beijing Information Science & Technology University, Beijing 100192, China
Permanent magnet motor in the process of running, the permanent magnets provided the magnetic field , the core will have a strong attraction, produce the cogging torque and torque ripple, vibration and noise and other disharmony factors, seriously affect the control precision of the motor system.Therefore, in the design of permanent magnet wind turbine generator, weaken the cogging torque is very important.
Key words: Permanent magnet motor / control precision / cogging torque
