摘要
针对感应电动机串级调速系统转子位置检测器存在的缺点，提出了基于近似积分原理工作的转子位置检测器的工作原理，其幅值系数、附加相角变化小，实验效果及工业运行实验结论可靠。
Put forward the work principle of rotor location detecting device which works approximately on integration theory, the coefficient of range value, the phase angle additional and the testing effect as well as result of industry operating test.
