ELECTROMAGNETIC CLUTCH COIL ASSEMBLY, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic clutch coil assembly that is disposed in a compressor of an air conditioner for a vehicle and can prevent lead wires connected to both ends of a coil winding from being damaged or short-circuited by vibration of the vehicle or high temperature during operating the compressor, and its manufacturing method. SOLUTION: This manufacturing method comprises a forming stage of winding a coil coated with an adhesive to form the coil winding, a heating stage of heating the coil winding while being pressurized in the laminating direction, and a hardening stage of hardening the adhesive by cooling in the pressurizing state. In the heating and hardening stages, the adhesive between two adjacent coil layers in the laminating direction is moved to an empty space around it. The coil winding, a bobbin, and a cover are assembled in a field core assembly.
