摘要
从异步电动机的稳态等效电路出发,推导出了功率因数与转差角频率之间的关系。根据这一关系,建立了基于恒功率因数的异步电动机转差频率矢量控制系统。实验表明,该系统在低负载时节能效果明显。
This paper deduces the relationship between power factor and slip angle frequency based on equivalent circuit of induction motor in stable state.According to this relationship,frequency vector control system is formed based on constant power factor.The experiment indicate that the energy-conserving effect is especially obvious under light loads.
