Low-speed large-torque permanent magnet motor all-in-one machine

Abstract

The invention relates to a low-speed large-torque permanent magnet motor all-in-one machine which comprises a shell, a permanent magnet motor is arranged in the shell, a push-pull mechanism is arranged on one side of the permanent magnet motor and comprises a limiting plate fixedly connected with the shell, and a threaded rod is arranged on one side of the limiting plate. One end of the threaded rod is in threaded connection with the limiting plate and the shell and is fixedly provided with a rotating head, the other end of the threaded rod is provided with a clamping mechanism, the clamping mechanism comprises a clamping base rotationally connected with the threaded rod, a clamping groove is formed in the top face of the clamping base, and a groove is formed in the side face, facing the permanent magnet motor, of the clamping base; a clamping block is fixedly installed at the position, corresponding to the groove, of the permanent magnet motor, the clamping mechanism is pulled to move through rotation of the threaded rod, the permanent magnet motor is moved to the set position, the opening and closing door is opened, and therefore the permanent magnet motor can be conveniently taken out for maintenance.

Description

technical field [0001] The invention relates to the technical field of permanent magnet motors, in particular to a low-speed and high-torque permanent magnet motor integrated machine. Background technique [0002] At present, removing mechanical devices such as hydraulic couplings and multi-stage pulleys, and adopting low-speed permanent magnet direct drive systems can give full play to the advantages of low-speed permanent magnet synchronous motors; however, in many cases, due to the size of permanent magnet direct drive motors Because of large size, high tonnage, and limited site conditions, the old low-speed permanent magnet motor cannot be installed and used normally. [0003] Such as figure 1 In the prior art shown, after the traditional low-speed high-torque permanent magnet motor has been used for a long time, there will be a small amount of dust on the output shaft of the permanent magnet motor, which will easily affect its operation, and it is inconvenient to disas...

Problems solved by technology

[0002] At present, removing mechanical devices such as hydraulic couplings and multi-stage pulleys, and adopting low-speed permanent magnet direct drive systems can give full play to the advantages of low-speed permanent magnet synchronous motors; however, in many cases, due to the size of permanent magnet direct drive motors Due to large size, high tonnage, and limited site conditions, the old low-speed permanent magnet motor cannot be installed and used normally.

[0003] like figure 1 In the prior art shown, after the traditional low-speed high-torque permanent magnet motor has been used for a long time, there will be a small amount of dust on the output shaft of the permanent magnet motor, which will easily affect its operation, and it is inconvenient to disassemble it and the reducer for maintenance. At the same time, due to the influence of the humid environment around electrical components such as permanent magnet motors and reducers, it is easy to reduce the service life of electrical components such as permanent magnet motors and reducers
