六相异步电动机能耗制动瞬态仿真研究

对六相异步电动机能耗制动的瞬态过程进行仿真分析。为了得到瞬态特性,建立了六相异步电动机在静止d-q-0坐标系下的混合磁链瞬态数学模型。编写计算机仿真程序,通过实例对六相异步电动机的能耗制动的瞬态过程进行仿真计算。仿真结果表明六相异步电动机可以在两套绕组中通入较小的直流电流获得较强的恒定磁场,从而产生较大的制动转矩。

Transient Simulation of Energy Losses Braking for Six-Phase Asynchronous Motors

The transient analysis of energy loss braking operation process of six-phase asynchronous motors was presented. To get the transient state performances, the mathematics model with mixed magnetic linkage of six-phase asynchronous machines was proposed in d-q-0 stationary reference frame. The computer simulation program was compiled. The program was applied to simulate transient process of energy loss braking operation process of six-phase asynchronous motors through an example. Emulating results showed that six phase motor could generate strong constant field when its two sets coils connected to small direct current,and got strong braking torque.
