ROTOR STRUCTURE OF WOUND ROTOR DRIVING MOTOR

摘要

A rotor of a wound rotor driving motor is provided. The rotor includes a rotor body that is rotatably installed with a predetermined air gap within a stator and in which a rotor coil is wound in a plurality of rotor teeth. A bobbin is fixed to the rotor body by the rotor coil disposed at opposing sides of an axial direction of the rotor body and supports the rotor coil. The rotor body forms a plurality of air movement passages that are opened to the exterior in an axial direction therein, and the bobbin forms a plurality of connection passage that are coupled to the air movement passages.
