    • In a linear pulse motor which includes: a movable body having an iron core provided with a coil or coils and side plates for supporting the iron core; a stationary body having magnetic circuit forming means for forming a magnetic circuit with the iron core across an air gap between the iron core and the magnetic circuit forming means; an axle fixed to the movable body, and wheels supported rotatably on end portions of the axle, respectively, and rollable on and along the stationary body; wherein the coil or coils are energized by pulses of a predetermined drive frequency to impart a stepwise magnetic drive force to the movable body, the length of the axle between the wheels is so determined that a noise level peak frequency or resonant frequency of the movable body is sufficiently far from the predetermined drive frequency.
    • 一种线性脉冲电动机,包括:具有设置有线圈或线圈的铁芯的移动体和用于支撑铁芯的侧板; 固定体,具有磁铁形成装置,用于与铁芯形成磁铁,穿过铁芯和磁路形成装置之间的气隙; 固定在移动体上的轴,以及分别支承在车轴的端部上并能够在固定体上并沿其旋转的车轮; 其中所述线圈或线圈由预定驱动频率的脉冲激励以向所述可移动体施加逐步磁力驱动力,所述车轮之间的所述轴的长度被确定为所述可移动体的噪声水平峰值频率或谐振频率 距预定的驱动频率足够远。
