发明名称 Rotor balance structure
摘要 A rotor balance structure, which comprises a vane shell, a rotor case installed on the inner side of the vane shell, and a magnet installed on the inner side of the rotor case. The rotor is coupled with a stator, which comprises a coil and a magnetic conduction silicon steel set. When the coil on the stator is provided with an electrical current and generates a magnetic field, the magnet is attracted through the magnetic conduction silicon steel set to rotate the rotor balance structure. The feature of the rotor balance structure of the present invention is in that a magnetically conductive plate is included and installed under the inner side of the vane shell top. The magnetically conductive plate does not have any magnetic conduction with the rotor case but has an attractive magnetic interaction with the coil so that the rotational balance of the rotor balance structure can be improved.
