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.

A motor unit having an insulation member is provided. The motor unit includes rotor cores formed in a radial direction on an exterior circumference of a motor shaft and a slot formed therebetween. Shoes are formed in a rotation direction and an opposite rotation direction of the motor shaft at an outer end portion of each rotor core, and an exposure passage is formed therebetween. A bottom surface is formed proximate to the motor shaft within the slot. Further first and second interior surfaces are connected to the bottom surface and are formed at the rotation direction side and the opposite rotation direction side of the motor shaft within the slot. An insulation member contacts the first and second interior circumferences of the shoes adjacent to the bottom surface and is disposed proximate to at least one portion of the exposure passage.

A rotor of a wound rotor synchronous motor is spaced apart from an interior diameter surface of a stator by a predetermined gap, and includes a plurality of teeth wound by a rotor coil, and circumferentially spaced apart from each other by a distance, where a slot is formed between the teeth, each tooth is formed with a shoe facing an interior diameter surface of the stator, and both ends of the shoe protrude in a direction of both ends of an adjacent shoe, where each tooth includes a first part corresponding to a winding body of the tooth and a second part extending in the direction of both ends of the adjacent shoe from both sides of the first part.
