Abstract
A rotary electric machine-manufacturing apparatus utilized to implement a process of infiltrating varnish into wire-wound coils of a rotary electric machine, and of curing the varnish, an apparatus includes a rotator 2 supporting a work S attached with the wire-wound coils Sc and rotating the work; and a high-frequency power supply device supplying electric power to the wire-wound coils. It is thus possible to support and heat up the work without having devices that surround the work S, thereby positioning a varnish dropping-infiltrating device 6 appropriately. Further, there is no need to change a stage as conventional heat-up processes with an oven or a hot blast-circulating furnace did, and an entire process from pre-drying to curing can be implemented at a single stage.
