    • The BL motor reduces power consumption with asymetrical driving coils and improves the performance. A printed circuit board (3) detects the revolving speed of rotor (2) and is installed between a stator (1) and the rotor (2). The printed circuit board (3) forms the semi-circular type in order to increase the number of wires. The current of the stator coils magnetizes the coil (1a) and the flux of the magnet (2a) revolves the rotor (2) . The half of the stator coil secures the space of the speed detection printed circuit board (3) and thus the flux density is increased under the condition of the same volume.
    • BL电机通过非对称驱动线圈降低功耗,提高性能。 印刷电路板(3)检测转子(2)的转速并安装在定子(1)和转子(2)之间。 为了增加导线数量,印刷电路板(3)形成半圆形。 定子线圈的电流使线圈(1a)磁化,磁体(2a)的磁通使转子(2)旋转。 定子线圈的一半固定速度检测印刷电路板(3)的空间,因此在相同体积的条件下磁通密度增加。
