ABSTRACT:
An armature stator comprises an iron core and a coil directly mounted on the iron core. The coil is composed of wound electric wire which has a coating comprising an inorganic material, such as ceramic. A bonding material of the inorganic material is formed over the coil and iron core for filling any gaps and adhering the coil and iron core together into a unitary structure. To improve the reliability of the coil, after the electric wire is wound to form the coil, a filling material comprised of the inorganic material is formed over the coil by vacuum impregnation, and then sintered so as to repair defects in the coating disposed on the electric wire. After the bonding material is formed over the coil, which is directly mounted on the iron core, it is cured under high temperature. The armature stator thus constructed can be used with high reliability in high temperature and high vacuum applications.
