ABSTRACT = {To solve the problems of large losses and low productivity of permanent magnet synchronous generators used in wind power systems, the field-circuit coupling method is used to accurately solve the electromagnetic field and temperature field of the generator. The loss distribution of the motor is accurately obtained by considering the influence of external circuit characteristics on its internal physical field. By mapping the losses to the corresponding part of the three-dimensional finite element model of the motor, the temperature field is solved, and the global temperature distribution of the generator, considering the influence of end windings, is obtained. By changing the air gap length, permanent magnet thickness, and winding conductivity, the relationship between the loss, temperature rise, and exergy efficiency can be obtained. By optimizing the air gap length, permanent magnet thickness, and winding conductivity, the best configuration and material properties can improve the efficiency of the motor by up to 4%.},
