Anti-creeping permanent magnet synchronous motor

Abstract

The invention belongs to the technical field of motors, and particularly relates to an anti-creeping permanent magnet synchronous motor. The anti-creeping permanent magnet synchronous motor comprisesa case, a partition plate, heat dissipating holes, a first bearing, a second bearing, a rotating shaft, a rotor, an insulating plastic sleeve, a stator, an insulating plastic mounting ring, a coolingfan, a fan hood, through holes, fixing blocks, circular holes, cylinders, springs, a movable rod, a through groove, limiting strips, strip-shaped grooves and a ceramic sleeve. The anti-creeping permanent magnet synchronous motor is reasonable in structure, through the cooperation effect of the cylinders, the springs, the movable rod, the fixing blocks, the circular holes, the limiting strips and the strip-shaped grooves, the anti-creeping permanent magnet synchronous motor and the case can be mounted, compared with a traditional mounting mode, the anti-creeping permanent magnet synchronous motor is convenient and quick to mount and demount, the labor strength is low, and thus the interior of the fan hood can be cleaned and maintained conveniently; and the insulating plastic sleeve, the ceramic sleeve and the insulating plastic mounting ring are arranged between the stator and the case, direct contact between the stator and the case can be avoided, and the anti-creeping effect is achieved through the insulating effect of the insulating plastic sleeve, the ceramic sleeve and the insulating plastic mounting ring.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a leakage-proof permanent magnet synchronous motor. Background technique [0002] The permanent magnet synchronous motor uses permanent magnets to generate the magnetic field of the motor. It does not need excitation coils or excitation current. It has high efficiency and simple structure. It is a good energy-saving motor. With the advent of high-performance permanent magnet materials and the rapid development of control technology. Permanent magnet The application of motors will become more extensive. [0003] One side of the permanent magnet synchronous motor is generally equipped with a cooling fan for heat dissipation. The cooling fan is generally equipped with a windshield for protection. After long-term use, dust may accumulate inside the windshield and needs to be cleaned. The windshield and the permanent magnet synchronous motor are generally passed through If it is insta...

Problems solved by technology

[0003] One side of the permanent magnet synchronous motor is generally equipped with a cooling fan for heat dissipation. The cooling fan is generally equipped with a windshield for protection. After long-term use, dust may accumulate inside the windshield and needs to be cleaned. The windshield and the permanent magnet synchronous motor are generally passed through If it is installed with bolts or screws, it is inconvenient to disassemble and install, so it is not easy to clean; the stator of the permanent magnet synchronous motor will have current, and it is generally installed on the casing, and leakage may occur
