Everson Tesla has long supported the power generation industry, always utilizing innovative, practical approaches to solve challenging problems. Proven capabilities in design, material selection, prototype modeling, coil winding and insulation systems have placed Everson Tesla among the elite suppliers for coils used in rotating field applications.
Transitioning from large DC stationary field coils and rotating fields for synchronous motors to highly reliable and efficient rotor coils for today's turbo generators exemplifies the manufacturing diversity that Everson Tesla has achieved over the past 75 years. A dedicated, multiple-shift facility has been established to meet the growing industry demand.
Everson Tesla currently supplies rotor coils, either insulated or uninsulated, in several configurations:
- C-Piece
- Continuous Wound
- Square Corner
New and Replacement Stator Coil Design
Computer design tools and specialized manufacturing tools enable us to provide customers with reliable coils of uniform shape. Coils can be insulated using one of Everson Tesla Incorporated's proven insulation systems or using the customer's insulation system when desired. Wire insulation is available in enamel, Dacron glass, Kapton, and mica tape systems for high voltage coils.
New and Replacement Field Coil Design
Computer modeling and specialized manufacturing tools enable us to provide customers with reliable coils of uniform shape and size. Coils can be supplied without insulation or insulated using one of Everson Tesla's proven insulation systems or the customer's insulation system. Coils can be wound from round, square, or rectangular conductor utilizing either wet winding techniques or VPI'd following winding. Strap coils can be continuous wound, brazed corners, or a combination of brazing and winding.
New and Replacement Stator Coil Manufacture
Specialized manufacturing tools and processes enable us to provide customers with reliable coils of uniform shape and size. Our machine fed taping of the slot portion of a high voltage stator coil maximizes the effectiveness of the ground insulation. Computerized spreading of full loop coils assures uniform geometry. Surge and dielectric testing of coils during manufacture and Tan Delta and Partial Discharge testing of fully cured coils and bars assures all coils meet stringent quality requirements. High potential testing up to 75KV allows for destructive sample testing to assure insulation systems meet the most demanding requirements.
New and Replacement Field Coil Manufacture
Specialized forming, brazing, welding, and cutting processes enable us to provide customers with any size and shape of coil. Custom forming tools limit deformation in continuous wound coils, eliminating the need to grind coils and preserving more of the conductor cross section, resulting in lower operating temperatures. Overlap, butt, scarf, mitered, and interlocking joints are available for brazing or TIG welded joints.
