A linear motor includes a stator module, a rotor module and an extension rod. The stator module includes a first stator unit and a second stator unit. The first stator unit includes an upper end cap including an upper holder member and an upper bobbin integrally extended from the upper holder member. The second stator unit includes a bottom end cap and a second winding. The bottom end cap includes a bottom holder member and a bottom bobbin connected to the bottom holder member and abutted against the upper bobbin. The rotor module is rotatably mounted in the stator module. The extension rod is linearly movably mounted in the stator module. The upper bobbin is integrally extended from the upper holder member. The fabrication of the linear motor is simple, ensuring a high level of precision. |
