Resin-molded stator, a method of manufacturing the same, and a rotary machine using the same |
摘要 |
A highly reliable resin-molded stator not suffering insulation breakdown between different phases of stator coils even when the operation mode is repeated where the output of a rotary machine using a resin-molded stator is to be increased from the level under a stopped status to the maximum achievable level within a short time. Also provided are methods of manufacturing such a stator, and a rotary machine using the same. The a resin-molded stator of the invention comprises a stator core, electrically insulated stator coils wound around the plurality of slots or protrusions provided in the axial direction of the stator core, and molding resin with which are molded the stator core and the stator coils located at the aforementioned slots or protrusions. At the stator core end, non-adhesive structure is established between the molding resin and at least one of the end faces of the stator core.
