A linear motor with enhanced cooling performance, including: a stator including multiple magnetic force generating members provided in a row; a moving element including multiple coils provided in a row in an axis line direction of the stator and wound around an outside of the stator; and a heat transfer member dissipating heat generated by the coil which is between adjacent coils and along a side of the coils.
1. A linear motor comprising:
a stator including multiple magnetic force generating members provided in a row;
a moving element including multiple coils provided in a row in an axis line direction of the stator and wound around an outside of the stator; and
a heat transfer member dissipating heat generated by the coils which is between adjacent coils of the multiple coils and along a side of the coils, wherein
the heat transfer member includes a heat collection section with a flat surface in contact with an end side surface of a coil of the multiple coils and the heat collection section includes a curved outer circumferential surface in a coil winding direction.
2. The linear motor according to claim 1 , wherein the heat transfer member is a heat pipe comprising the heat collection section, a heat dissipation section that contacts the heat collecting section and protrudes in a direction away from the coil, and a heat dissipation member provided on the heat dissipation section.
3. The linear motor according to claim 2 , wherein the heat dissipation section is located above the heat collection section.
4. The linear motor according to claim 1 , wherein the heat transfer member is provided in a gap formed between the adjacent coils to give an outgoing line outside the coil for a wire wound at a beginning or a wire wound at an end of the coil.
