中文摘要：

由于盘式电机气隙较大且主要参数随半径变化,采用传统电机分析方法在分析盘式电机时会造成较大误差。提出一种用于分析盘式电机的新型电磁模型,模型采用分环计算和求解气隙矢量磁位方程的方法提高模型精度。利用一维磁场分析的方法得到模型的T型等效电路。横向边端效应的影响被引入计算等效气隙长度的过程,省去了等效电路中的横向边端效应系数。利用等效电路分析了励磁电感、转子电阻和电磁转矩随转差率变化的情况。将三相静止坐标系下的三相电压、电感和电流转化为两相旋转坐标系下的对应值,以采用间接磁场定向控制。通过制作一台样机,并对其进行分析、仿真和实验验证,其结果吻合度高,电机调速性能良好,证明所提模型是正确和有效的。

英文摘要：

Because the large airgap and main factors that vary with diameter,traditional analysis method results in large error in analyzing disc motor.A new disc induction motor electromagnetic model was proposed.Sub-loop calculation and airgap vector magnetic potential equation were used to improve the model accuracy.T model equivalent circuit of the model was achieved based on one-dimensional model.The influence of transverse end effect was taken account of by directly introduced into equivalent airgap length,leaving out the transverse end effect factors.Field inductance,rotor resistance and torque vary with slip ratio were analyzed.The three phase voltages,flux linkages and currents were transformed into two phase relevant equations in synchronous axis.Realized the implementation of indirect-field oriented control.A prototype machine was produced and analyzed by the proposed model,simulations and experiments were carried out.the results match well,speed regulating performance is good,which indicate that the new model is correct and effective.
