Abstract: A method for gel curing a varnish of a stator assembly includes: applying an electrically-insulating material to a plurality of electrical conductors of a stator assembly; monitoring a temperature of the stator assembly using at least one temperature sensor; determining whether the temperature of the stator assembly has reached a target temperature; in response to determining that the temperature of the stator assembly is equal to the target temperature, heating the stator assembly using the induction heating element to maintain the temperature of the stator assembly at the target temperature for a predetermined amount of time; determining whether the temperature of the stator assembly is equal to the final target temperature; in response to determining that the target temperature is not equal to the final target temperature, increasing the target temperature by a predetermined amount of degrees.

Abstract: A bolt includes a body and a threaded portion formed on the body. The bolt further includes a phosphate base coat, which covers at least the body and is in direct contact with the body. The bolt also includes a PTFE overcoat, which substantially covers the phosphate base coat and is separated from the body of the bolt by the phosphate base coat.

Abstract: A method of engaging wire ends of a stator assembly. The method involves advancing multiple fingers radially inwardly toward the wire ends, and rotating the fingers. The fingers have protrusions that engage the wire ends. A tooling assembly for engaging the wire ends has a first plate, a second plate, and has the fingers. The first plate has slots, and the second plate has teeth. The fingers have pins that ride in the slots of the first plate, and the fingers have teeth that mesh with the teeth of the second plate.
