Method and structure of winding of stator for rotation detector, and electric motor comprising rotation detector
摘要：
The N1(s) turns of an output winding is divided by a split ratio α into N1a(s) turns of an output winding (1a) and N1b(s) turns of an output winding (1b). The output winding (1a) is continuously wound around all slots as the undermost layer. Output winding 2, which is different in phase by 90 degrees from the output winding (1a), is continuously wound around all the slots over the output winding (1a). An output winding (1b) is continuously wound around all the slots over output winding 2. This equalizes the contribution of the output winding and output winding 2 to the flux linkage, thereby achieving high angle detection accuracy.
摘要（中）：

输出绕组的N1（s）匝被分压比α除以输出绕组（1a）的N1a（s）匝和输出绕组（1b）的N1b（s）匝。 输出绕组（1a）作为最下层连续缠绕在所有槽上。 与输出绕组（1a）相位相差90度的输出绕组2连续缠绕在输出绕组（1a）上的所有槽上。 输出绕组（1b）连续缠绕在输出绕组2上的所有槽上。这使得输出绕组和输出绕组2对磁链的贡献相等，从而实现高角度检测精度。
