The invention provides a motor. A motor according to an embodiment of the present invention is used for linearly moving an object back and forth along a rod having a predetermined length, and comprises: a housing; a rotor part rotatably mounted inside the housing via a bearing, the rotor part including: a rotor shaft coupled to the rod shaft and linearly moving back and forth along the rod during rotation; the plurality of magnets are arranged along the circumferential direction of the rotor shaft; and a stator part including: a closed-loop-shaped yoke part housed in the housing so as to surround the periphery of the rotor part; at least one stator core including a plurality of slots extending from the yoke toward the rotor side; and a coil wound around at least one of the plurality of slot portions, the stator core including a plurality of first slot portions around which the coil is wound and a plurality of second slot portions around which no coil is wound, the plurality of first groove portions are disposed so as to surround an arc portion corresponding to a [theta] angle in the entire circumference of an imaginary circle connecting end portions of the plurality of first groove portions and the plurality of second groove portions, and the plurality of second groove portions are disposed so as to surround an arc portion corresponding to a 2pi-[theta] angle in the entire circumference of the imaginary circle.

    本发明提供一种电动机。基于本发明的例示的实施例的电动机用于使对象物沿着具有预定长度的杆进行直线往返移动,包含:外壳;转子部,通过轴承可旋转地装配在所述外壳的内部,包含:转子轴,与所述杆轴结合,在进行旋转时沿着所述杆进行直线往返移动;以及多个磁铁,沿着所述转子轴的周向设置;以及定子部,包含:闭环形状的轭部,以包围所述转子部周围的方式内置于所述外壳;至少一个定子铁心,包含从所述轭部向所述转子侧延伸的多个槽部;以及线圈,卷绕在所述多个槽部中的至少一个槽部,所述定子铁心包含卷绕有线圈的多个第1槽部以及没有卷绕有线圈的多个第2槽部,所述多个第1槽部配置为包围将所述多个第1槽部及所述多个第2槽部的端部连接的假想圆的全周中相当于θ角度的圆弧部分,所述多个第2槽部配置为包围所述假想圆的全周中相当于2π‑θ角度的圆弧部分。
