Abstract

The utility model relates to the technical field of permanent magnet synchronous motors and particularly relates to a structure of a rotor of a permanent magnet synchronous motor (PMSM). The structure of the rotor of the PMSM comprises a rotating shaft, wherein two ends of the rotating shaft are sleeved with a front dynamic balancing plate and a rear dynamic balancing plate respectively. An iron core which is formed by splicing a plurality of rotor sheets is arranged between the front dynamic balancing plate and the rear dynamic balancing plate. The rotating shaft is arranged to penetrate the iron core. Each rotor sheet is provided with a T-shaped projection. The surface of the iron core is provided with a plurality of permanent magnets which are separately provided with a slide rail in clamping connection with the T-shaped projections. By improving the structures of the iron core and the permanent magnets, the permanent magnets can be effectively fixed by the iron core to guarantee that a motor cannot be damaged in the high-speed operation as the permanent magnets cannot shake off a protective sleeve or the binding force of a protective layer.
