High-speed light-load linear motor

The utility model relates to a high-speed light-load linear motor which comprises a lead screw, a stepping motor body and a nut, and a rotor iron core and a bearing are arranged in the stepping motor body. The lead screw serves as a motor rotor shaft to be assembled with the rotor iron core and the bearing in a matched mode, and the assembled stepping motor body is screwed with the nut. Compared with the prior art, the linear stepping motor has the advantages that the linear running speed of the linear stepping motor is improved and the output performance is improved as much as possible under the condition that the size is as small as possible. 本实用新型涉及一种高速轻载线性电机，包括丝杠、步进电机本体和螺母，所述的步进电机本体内部设有转子铁芯和轴承；所述的丝杠作为电机转子轴与转子铁芯和轴承进行配合组装，将组装后的步进电机本体与螺母进行旋合。与现有技术相比，本实用新型具有实现了在尽可能小的尺寸下，提高线性步进电机的直线运行速度，并尽可能提高输出性能等优点。
