A high-precision finish that minimizes the thickness difference between the inner and outer rings to the limit!
Our edgewise coils are primarily used as the salient pole rotors in hydroelectric generators, diesel generators, and large synchronous motors. When using coils in rotors, strength and precision that can withstand deformation due to centrifugal force during rotation are required. This is especially true for large edgewise coils used in rotors, which demand considerable strength and precision. Our edgewise coils meet these high demands, and we continuously improve the facilities and technology necessary for manufacturing. **Our Strengths** - Expertise in producing large edgewise coils used in hydroelectric generators, diesel generators, and large synchronous motors. - Possession of winding machines capable of accommodating diverse edgewise winding, enabling integrated production from winding to insulation. - Extensive experience and facilities in edgewise coil manufacturing allow for cost reduction and shortened lead times. - As one of Japan's leading manufacturers of edgewise coils, we support heavy electrical manufacturers both domestically and internationally. *For more details, please feel free to contact us.*

Company information
Since our establishment in 1953, we have been producing copper alloy castings. Leveraging the know-how we have cultivated in copper alloy castings, we shifted around 1980 to a specialized factory that conducts integrated production from the manufacturing to assembly of edgewise coils and field poles used in electric motors and generators. We have continuously introduced new technologies to produce high-quality and high-performance products. Today, as a leading company in the manufacturing of edgewise coils and field poles, we deliver products that support industries worldwide, both domestically and internationally.
