Electromagnetic Design and Temperature Field Analysis of Offshore Semi-direct Drive Permanent Magnet Wind Turbine
Taking the offshore 16MW semi-direct drive permanent magnet wind turbine as the research ob-ject,this paper studied the electromagnetic characteristics,cooling structure design and temperature field simulation under unequal air gap conditions based on the finite element analysis method,and the results show that the optimized motor can reasonably reduce the motor loss,improve the electromagnetic perform-ance,and the cooling method combining water jacket cooling and air water cooling has good heat dissipation effect.Through the type test,the rationality of the motor design was verified.The design of this motor has played an important role in the development of large-scale offshore permanent magnet wind turbines.
