IntegraCoil Stator Coils —
designed for on-site rewinds and very large AC stators
High-voltage, AC motors and generators are designed to have multi-turn, form-wound stator coils. In these cases, the stator winding has three separate but interrelated insulating barriers: strand to strand insulation, turn to turn insulation, and ground insulation. Failure of any of these barriers will prematurely terminate the service life of the machine.
All IntegraCoil B-Stage Hard Coils are manufactured to IPS specification with regards to insulation materials and manufacturing processes. The IntegraCoil design is validated thru extensive qualification testing to prevent strand-to-strand and turn-to-turn shorts which may result from voltage surges. The ground wall insulation contains multiple layers of half-lapped, resin-rich Mica tape, engineered for your specific voltage requirements. On 6.6 kV and higher voltage ratings, we also apply conductive corona tape to the slot portion of the coil to prevent corona discharges in the slot, as well as stress grading tape to help bleed the voltage to non-damaging levels.
25+Year Rewind Design
IntegraCoil stator coils are made using Class F (155 ˚C) rated insulation materials, and meet or exceed the following standards:
IPS engineers have designed IntegraCoil rewinds for a 25+year life cycle by incorporating processes and materials that increase your electric motor reliability and mitigates the following winding failures and aging factors:
