Abstract
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.
