Abstract
A Wound Rotor Synchronous Motor (WRSM) includes a rotor body that is rotatably installed at a predetermined gap within a stator and a rotor coil that is wound at a plurality of rotor teeth. The WRSM includes: bobbins that are each disposed at both sides of a shaft direction of the rotor body so as to support the rotor coil and that are fixed to the rotor body by the rotor coil; a wedge member that is inserted in a shaft direction between rotor teeth of the rotor body so as to protrude to the outside of both ends of the rotor body, the wedge member supporting the rotor coil; and end coil covers that enclose a protruded portion of the wedge member at both sides of the shaft direction of the rotor body and that are each mounted at the bobbins.
