A linear motor (1) includes a stator module (10), a rotor module (20) and an extension rod (30). The stator module (10) includes a first stator unit (11) and a second stator unit (12). The first stator unit (11) includes an upper end cap (111) including an upper holder member (1111) and an upper bobbin (1112) integrally extended from the upper holder member (1111). The second stator unit (12) includes a bottom end cap (121) and a second winding (122). The bottom end cap (121) includes a bottom holder member (1211) and a bottom bobbin (1212) connected to the bottom holder member (1211) and abutted against the upper bobbin (1112). The rotor module (20) is rotatably mounted in the stator module (10). The extension rod (30) is linearly movably mounted in the stator module (10). The upper bobbin (1112) is integrally extended from the upper holder member (1111). The fabrication of the linear motor (1) is simple, ensuring a high level of precision. |
