摘要：

In this paper, taking a high-speed permanent magnet generator (HSPMG) as an example, the unbalanced load limit of HSPMG is studied based on the analysis of the electromagnetic and temperature fields of the generator. The influences of different degrees of unbalance currents on the losses of the generator are studied, and the influence mechanisms of unbalance currents on the losses of the rotor sleeve and permanent magnet are revealed. Based on the theory of fluid dynamics and heat transfer, the temperature field distribution of HSPMG under the unbalanced load condition is studied, and the non-linear relation between the current unbalance and the temperature field of HSPMG is determined. Finally, the load unbalance resistant limit of HSPMG is determined. These conclusions can provide a reference for determining the unbalanced load limit of HSPMG. It is also helpful for improving the reliability of HSPMG under abnormal working conditions.
