    • In a brushless motor, a rotor magnet comprises a main magnetizing member with alternate N-poles and S-poles and a subsidiary magnetizing member for detecting rotational speed disposed at an inner side and having N-poles and S-poles arranged at a smaller pitch in comparison to the main magnetizing member. A stationary plate is provided with stator coils opposed to the main magnetizing member and a detecting substrate has a pattern in opposition to the subsidiary magnetizing member for detecting rotational speed. The detecting substrate is installed on the stator coils, and leads from the detecting substrate extend through the center of the stationary plate towards the rear side thereof, to avoid the signal distortion of prior art designs.
    • 在无刷电动机中,转子磁体包括具有交替的N极和S极的主磁化部件和用于检测设置在内侧的旋转速度并具有以较小间距排列的N极和S极的辅助磁化部件 与主磁化部件相比。 固定板设置有与主磁化构件相对的定子线圈,并且检测基板具有与用于检测转速的辅助磁化构件相对的图案。 检测基板安装在定子线圈上,检测基板的引线通过固定板的中心朝向其后侧延伸,以避免现有技术设计的信号失真。
