Abstract
A method for manufacturing electrodynamic machine conductive coils, such as alternating current induction motor stator coils. A continuous strand of insulation coated wire is formed into a generally planar elongated closed loop having a circumference and an outer surface. Thereafter a permanent insulation layer is applied to the closed loop outer surface, preferably by spiral wrapping insulating tape about the circumference of the closed loop with a tape wrapping machine. The insulating tape has a catalytic chemical compound including at least one part of a multi-part epoxy resin. The closed loop is shaped into a rigid conductive coil by application pressure, in order to conform the coil to a desired profile. Application of the permanent insulation layer to the closed loop prior to its final shaping enables machine insulation taping over a larger portion of the coil circumference and reduces need for slower and more expensive hand taping.
