开槽实心转子电机转子端部系数的计算与比较
Calculation and Comparison of Rotor End Factors of Solid Rotor Induction Machines with Axial Slits
摘要
Abstract
When the nonlinearity of rotor magnetic circuit is taken into account,the huge computation of 3D finite element calculation of slitted solid rotor magnetic field is unavoidable.To simplify the calculation,the 2D FEM combined with end factors of smooth solid rotor is adopted generally.However,the calculation error increases along with the increase of slip when applying end factors of smooth solid rotor for the slitted rotor.This paper puts forward a new rotor end factor for slitted solid rotor using an approximate calculation method due to the eddy current distribution in the slitted rotor.With the 2D FEM and the raised end factor,the effect of saturation in both stator and rotor core and the axial finite length of rotor are taken into account.The calculation results using different smooth rotor end factors and the raised slitted rotor end factor are compared with each other.And the simulation results using slitted rotor end factor agree well with the experimental test results on model machines with different number of rotor slitted.This indicates the raised slitted rotor end factor is suitable for the parameter calculation and optimal design of slitted solid-rotor induction machine.关键词
