Abstract:
1. A rotary transformer-type resolver comprising: an inner core on which a rotary transformer output winding is wound, wherein the inner core is adapted to receive a rotary shaft; a resolver rotor on which resolver excitation windings are wound; a spacer, which is located between the inner core and the resolver rotor, wherein a fixing groove is formed in the spacer, and a crossover, which connects said rotary transformer output winding and said resolver excitation windings, extends between said inner core and said resolver rotor and is accommodated by the fixing groove; a flange formed on the inner core between the spacer and the rotary transformer output winding, wherein a cutout groove, which accommodates the crossover, is formed in the flange, and wherein the cutout groove and the fixing groove are aligned in the axial direction of the resolver, and wherein the spacer and the inner core are formed as a unit, and a space, which extends in the axial direction, is formed between the spacer and the flange.
