ELECTROMAGNETIC DRIVE COIL UNIT AND MOLDING METHOD THEREOF

摘要

A method of molding an electromagnetic drive coil unit is provided which can secure satisfactory strength and waterproof properties. In a method of molding an electromagnetic drive coil unit in which a stator assembly 300 includes bobbins 310 and 312 having stator coils 309 and 311 wound thereon and yokes 307 and 308 in which an inner yoke 321 having magnetic pole teeth 320 and an outer yoke 323 having magnetic pole teeth 322 are combined and in which the stator assembly 300 and a power supply terminal 303 supplying power to the bobbins 310 and 312 are molded in a resin, an inner molding process is performed on the inside of the outer yoke 323 in a state in which ends of the stator coils 309 and 311 of the stator assembly 300 are connected to the power supply terminal 303 and an outer molding process is performed to cover an outer circumference of the stator assembly 300 having an inner molded portion 331 and an outside of the power supply terminal 303 after performing the inner molding process.
