| 摘 要： | 提出测量转子时间常数的简单方法。系统采用单相变频率交流电流，在这一电流切换到直流时观测定子电压瞬态伍。电压瞬态位作为调整交流电流频率的依据。本系统不需要附加硬件电路，对电机无任何外部限制。测试结果表明这一方法是有效的。

| Abstract: | This paper presents a new and single way to measure the rotor time constant. The system employs simple-phase ac current with varying excitation frequency, observing the voltage transient that occurs when this test current is switched to dc. The transient va1ue is used to tune the frequency of the ac current,no ad-ditional hardware and external constraints on the machine are required. Test results show that this scheme is valid. |
