PURPOSE:To obtain a rotor excellent in ventilating and cooling characteristic without external blowers, by arranging spider arms at angles in the radial direction. CONSTITUTION:Spider arms 3 are respectively arranged at angles theta in the radial direction, and both ends of the spider arms 3 are respectively connected to a rotor shaft 2 and connectors 4 by welding sections 8. After a core 1 is fitted on the connectors 4, they are firmly fixed together with cotters 7. As the result, the spider arms not only transmit torque, but function as the wings of a centrifugal fan for cooling action. |
