LEAD WIRE WITH INSULATION LAYER, MOTOR WITH USE OF LEAD WIRE WITH INSULATION LAYER, AND MANUFACTURING METHOD OF MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a lead wire with insulation layer, which hardly causes heat loss even for high-currency current, capable of stably securing desired current and voltage; a motor having an improved efficiency due to use of the lead wire with insulation layer; and a method for manufacturing the motor.SOLUTION: A lead wire 5 with insulation layer is disposed in a slot 4. The lead wire includes: an insulation layer 6 made of a hollow tube-shaped insulation material having long protrusions 9 or recesses extending along the axial direction on the inner face of a hollow tube-shaped wall part 8; and a lead wire 7 disposed inside the wall part of the insulation layer, having groove parts 10 or protrusions on the surface so as to be fitted in the protrusions or the recesses.
