Abstract :
The rotor structural design and anti-demagnetization method are studied on the 1120 kW permanent magnet synchronous motor (PMSM) in the design and manufacturing process in this paper. The rotor structure, which has the merits of sufficient anti-demagnetization and strong rigidity, is designed. Design and manufacture of the motor has been worked out
