METHOD OF MANUFACTURE FOR ENCASED COIL BODY AND ENCASED COIL BODY

摘要

Disclosed is a method of manufacture for an encased coil body which can be easily manufactured and provides excellent protection against the coil moving or deforming, wherein a coil is encased by being encapsulated in an electrically insulating resin. To form a resin casing layer to encase a coil (10) by injection moulding of a thermoplastic resin, the injection moulding step is divided into: a first formation step wherein a first body (22-1) including an outer circumference encasing part (46) is formed while the inner circumference of the coil (10) is in contact with a first mould and the coil (10) is positioned and constrained in the radial direction; and a second formation step thereafter wherein a second body including an inner circumference encasing part is formed while the first body (22-1) and also the coil (10) are positioned in a second mould.
