ABSTRACT:
A heat tack application involves arranging an adhesive between a strand of conductive material and a strand of insulation material; applying a temperature of about 100-300° C. and a pressure of about 5-100 psi for about 5-120 seconds to tack the adhesive. A stack can thereby be formed, and a plurality of stacks assembled to form a nascent rotor coil that is subsequently arranged in a rotor slot. An applied temperature of about 100-500° C. and a pressure of about 100-1,500 psi can fully cure the adhesive after the coil is arranged within the rotor slot. Depending on the context of use, the conductive material may more generally be a first component, and the insulation material may more generally be a second component.
