利用异步电动机电压同步坐标系,得出电动机稳态运行时电磁转矩与转速的关系。运用动力学理论分析反向回转双机驱动振动系统的动力学特性,建立系统频率俘获的方程,得到实现频率俘获的条件及俘获频率和两偏心转子相位差的理论计算方程。利用非线性动力学理论,建立了频率俘获的稳定方程。利用Routh-Hurwitz准则获得系统稳定性条件。
英文摘要：
The relation between the electromagnetic torque and the rotor speed of an induction motor is derived in the synchronous frame of the stator voltage. The dynamic characteristic of a vibrating system with two-motor drives rotating in opposite directions is analyzed by using the dynamic theory and the equations of frequency capture are established. The conditions for implementing frequency capture and the equations of calculating capturing frequency and the phase difference are obtained. The stable equations of implementing frequency capture in the system are deduced by using nonlinear dynamics theory and the condition for system stability is obtained by using Routh-Hurwitz criterion.
