The invention discloses a self-heat-dissipation
rare earth permanent magnet synchronous motor. The motor comprises a
machine bin , wherein a front
machine cover and a rear
machine cover are arranged at two ends of the machine bin correspondingly, a filtering
assembly is arranged at the end, away from the machine bin, of the outer side of the front machine cover, a bearing B is arranged in the center of the end, away from the machine bin, of the front machine cover, connecting rods are evenly arranged at the end, away from the front machine cover, of the inner side wall of the machine bin, andbearings A are arranged at the ends, close to each other, of the connecting rods. The motor is advantaged in that the front machine cover, the machine bin, the auxiliary
assembly, the fixing assemblyand the rear machine cover are used in cooperation, when the motor is disassembled for maintenance, excessive fixing screws do not need to be disassembled; when the front machine cover and the rear machine cover are installed, the front machine cover and the rear machine cover do not need to be manually supported to keep alignment of screws and screw holes, only the
insertion rods need to be inserted into the
insertion grooves, convenience of disassembly or
assembly of the motor is greatly improved, and stability of connection between the front machine cover and the machine bin and between therear machine cover and the machine bin can be further improved through the auxiliary assemblies.
