A ROTOR OF GENERATOR AND ELECTRIC MOTOR

摘要

A rotor of a generator and a motor is provided to distribute a stress to a whole nut member during a high speed rotation by coupling the coupling bolts in one nut member at the same time. A rotor(100) includes a plurality of magnets(M) and a fixing unit(200). A plurality of magnets is installed along an outer circumference of the rotor. The fixing unit prevents separation of the magnet from the rotor by a centrifugal force generated by rotation of the rotor. The fixing unit includes a pressurized frame(210), a plurality of coupling bolts(220), and a nut member(230). The pressurized frame is installed between the magnets in order to pressurize the magnet. A plurality of coupling bolts is installed with a fixed interval according to a longitudinal direction of the rotor. A plurality of coupling bolts couples the pressurized frame with the rotor. The nut member is coupled in a bottom end of the coupling bolt in order to fix the coupling bolt.
