本发明的宗旨在于提高表用步进电动机的机电换能效率,以及使线圈组件薄型化。电子表小型化、薄型化的最大障碍,是电池占据空间大。人们总希望提高电池以外的表机系统的电气效率,降低电耗,使用尽量小的容积电池。作为机电换能器的步进电动机,其定子线圈架,线圈直径及线圈的回转结构往往成为决定手表厚度的主要因素。本发明的着眼点,就是通过改进使线圈所产生的磁通量能
The object of the present invention is to improve the electromechanical transduction efficiency of the stepping motor for table use and to reduce the thickness of the coil assembly. Small electronic watch, the biggest obstacle to thin, is the battery occupy a large space. People always want to improve the electrical efficiency of the meter system outside the battery, reduce power consumption, use the smallest battery capacity. As the stepper motor of electromechanical transducer, the stator bobbin, the coil diameter and the rotating structure of the coil are often the main factors determining the thickness of the watch. The focus of the present invention is to improve the magnetic flux energy produced by the coil
