Abstract
An iron core member of a resolver, which is a one-piece member integrally formed of iron powder. The iron core member includes an annular core section and multiple pole sections annularly arranged on outer circumference of the core section at equal intervals and projecting from the outer circumference of the core section. Each pole section has recessed sections. Enameled wires can be conveniently wound around the recessed sections to form coils located in the recessed sections. The pole section further has multiple projection posts. After the winding process is completed, the terminals of the enameled wires are hooked and located on the projection posts. In comparison with the conventional iron core member, the present iron core member has lower iron loss and the manufacturing process is simplified.
