摘　　要：针对现有永磁同步发电机的转子位置测量方法,综合各种测量方法的不足,提出了一种增量式光电编码盘的测量方法,并对电机初始位置检测进行了实验与结果分析,实验结果表明了该方法是切实可行的,能够可靠并有效地检测出电机转子的初始位置。methods of all of them This article describes characteristics and application perm have anent magnet synchronous generator. All these of a variety of existing rotor position measurement methods can realize the rotor position detection, but limitations. The dissertation lists the shortcomings of various of methods, compares their advantages and disadvantages, then puts forward tn a new method called incremental photoelectric encoder. This method makes use of the photoelectric effect to realize the rotor position detection. According to the characteristics of the permanent magnet synchronous motor, this method is more applicable for determination of the rotor position. This method is relatively simple, while its accuracy is relatively high. Then the paper analyses the initial position of mo- tor and the experimental results of the detection. Finally, the experimental results verify that the method is feasible and correct, and can inspect the initial position of motor rotor effectively and reliably.
