Title:
REINFORCING, COOLING AND LUBRICATING STRUCTURE OF ROTOR ASSEMBLY OF HIGH-SPEED MOTOR, ROTOR ASSEMBLY, AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2024/078349
Kind Code:
A1
Abstract:
Disclosed in the present invention is a reinforcing, cooling and lubricating structure of a rotor assembly of a high-speed motor, comprising balance plates, rotor supporting devices, pin holes, longitudinal fastening assemblies, and a cooling and lubricating assembly. The balance plates are mounted on a rotating shaft of the motor. No less than two cake-shaped magnets are disposed between the balance plates. Mounting holes are uniformly formed in the circumferential direction of each balance plate. Each rotor supporting device is of a sheet-shaped structure disposed between the cake-shaped magnets, and is uniformly provided with a plurality of through holes in the circumferential direction. The longitudinal fastening assemblies pass, in the longitudinal direction, through the mounting holes, the pin holes, and the through holes having the same longitudinal axial position. The balance plates, the cake-shaped magnets, and the rotor supporting devices are fastened together in series by the longitudinal fastening assemblies. Also disclosed are a corresponding rotor assembly and a motor. The centrifugal force of a rotor can be effectively resisted, the rotating speed of the motor is improved, the air gap of the motor is not occupied, and the efficiency, torque, and power of the motor are not reduced, thereby effectively improving the performance of the motor.
