[0003] After the existing permanent magnet motor is used for a long time, the shaft will be relatively dry, and it is difficult to lubricate. The motor needs to be disassembled and lubricated, which greatly improves the work intensity of the staff and consumes a lot of time. Moreover, the motor If used for a long time, the permanent magnets of the rotor will generate a lot of heat. If the temperature is too high, it will easily burn out the rotor, thus reducing the service life of the rotor.

Abstract
The invention discloses a rotor structure of a permanent magnet synchronous motor. Annular diaphragms, cams, piston rods, oil collection funnels, exhaust pipes, connecting rods, permanent magnets, annular jet pipes, bellows, turbines, suction pipes, springs, oil inlet pipes, shafts, turntables, cross plates, sliding rods and support rods . The invention can better lubricate the lubricating oil by arranging the mutual cooperation between the cam, the suction pipe, the oil collecting funnel, the piston rod and the oil injection head, avoid manual disassembly and lubrication, and greatly reduce the work of the staff At the same time, it also shortens a lot of time; by setting the mutual cooperation between the chute seat, the slider, the annular rubber block, the bevel gear and the sliding rod, the lubricating oil can be wiped evenly better, so that the lubricating oil can be evenly coated On the surface of the rotating shaft, the lubrication efficiency of the rotating shaft is greatly improved.
Description
technical field [0001] The invention relates to a rotor structure, in particular to a rotor structure of a permanent magnet synchronous motor, belonging to the technical field of permanent magnet synchronous motors. Background technique [0002] Permanent magnet motors have the advantages of high efficiency, high power factor, and large speed range. Therefore, in high-speed applications, permanent magnet motors are favored. Compared with external permanent magnet rotor motors, inner rotor permanent magnet motors have small rotor radius and strong reliability. Advantages, become the first choice for high-speed motors, and the rotor of the motor is a vital part of the permanent magnet motor. [0003] After the existing permanent magnet motor is used for a long time, the shaft will be relatively dry, and it is difficult to lubricate. The motor needs to be disassembled and lubricated, which greatly improves the work intensity of the staff and consumes a lot of time. Moreover, th...
