Rotor structure of permanent magnet synchronous motor

Abstract

The invention discloses a rotor structure of a permanent magnet synchronous motor. The device comprises an annular cylinder, fixing rods, oil spraying heads, annular sponge blocks, oil guide pipes, sliding groove seats, sliding blocks, bevel gears, bevel pinions, rotating rods, annular partition plates, cams, piston rods, oil collecting funnels, exhaust pipes, connecting rods, permanent magnets, annular air spraying pipes, air boxes, turbines, suction pipes, springs, oil inlet pipes, rotating shafts, rotating discs, transverse plates, sliding rods and supporting rods. Through mutual cooperation of the cam, the suction pipe, the oil collecting funnel, the piston rod and the oil spraying head, lubricating oil can be better lubricated, manual disassembly for lubrication is avoided, the working intensity of workers is greatly reduced, Meanwhile, a large amount of time is also shortened; and through mutual cooperation of the sliding groove seats, the sliding blocks, the annular rubber blocks, the bevel gears and the sliding rods, lubricating oil can be better and evenly wiped, the surface of the rotating shaft is evenly coated with the lubricating oil, and the lubricating efficiency ofthe 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...

Problems solved by technology

[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.
