| Abstract: | Hybrid excitation permanent magnet synchronous generator with hybrid poles has permanent magnet and field windings in the rotor.The basic equation of this electric machine was established in order to study its performance.According to the structure of the rotor and the actual connects and spatial distribution of the stator windings,the characteristics of the inductance paramerters and the flux of the other loop created by permannent magnet were analyzed,and the expressions were given.The coefficients of each parameter expression were calculated using the finite element method,which took into account the shape of the magent poles and permannent magnet,and the simulation of the machine performance was performed using numerical methods.Simulation and experiment results agree well with test results on a prototype,which verifies the correctness of the simulation model and the accuracy of parameters calculation. |
