Abstract
Electric equipment is provided for mounting on vehicles and electrical machines having superior rust-prevention film, which makes it possible to prevent vehicles from generating red rust even if outer surface of magnetic core housing of the vehicle is damaged by bouncing a stone and the like during running, and also to provide manufacturing methods of the same. Any outer surface and surface exposed outward of the magnetic core housing is coated sequentially with a metal plated layer or an alkali zinc plated layer, chromate film or zinc phosphate film, and organic resin coating.
