Linear motor armature and linear motor |
摘要 |
In a linear motor, a can has a two-layer structure including an inner can 2 and an outer can 3, and an inner passage 7 formed between an armature winding 9 and the inner can 2 and an outer passage 8 formed between the inner can 2 and the outer can 3 are constituted by each can. Communicating portions 7A and 8A for causing the inner passage 7 and the outer passage 8 to communicate with each other are provided in the vicinity of a refrigerant supply port 5 in each of the cans 2 and 3 in such a manner that a refrigerant supplied from the refrigerant supply port 5 branches into the inner passage 7 and the outer passage 8 and thus flows. Consequently, it is possible to obtain a linear motor armature and a linear motor having a high cooling capability which can prevent the deformation of the can by using a conventional inactive refrigerant to improve the passage for the refrigerant.
