Analysis of electromagnetic and thermal characteristics of the PM generator with rectifier load

In view of the trend in recent years the wide application of HVDC system, in this paper, describes the electromagnetic properties and loss calculation of permanent magnet synchronous generator with rectifier load and no-load, analysis of the influence of the rectifier load on permanent magnet motor electromagnetic properties and loss. Based on the calculation of motor losses, application of Fluent software simulation to calculate the three-dimensional distribution and find out the highest point temperature, and to determine when the load on the motor with rectifier problems, and analysis of the problems with rectifier load motor reasons.
