Problems solved by technology

[0021] Disadvantages of Prior Art 2 The structural design of the mine-used permanent magnet integrated machine makes the motor special, and it can only work when it is integrated with the corresponding frequency converter structure. Once the frequency converter fails or one of the motors fails, the entire system will also fail. It will not work, which greatly reduces the reliability of the entire system, and it is very inconvenient to repair and replace.

Abstract

The invention relates to a mining permanent magnet synchronous motor technology and particularly relates to a separable mining permanent magnet synchronous frequency conversion and speed regulation all-in-one machine motor structure. The separable mining permanent magnet synchronous frequency conversion and speed regulation all-in-one machine motor structure comprises a motor shell, wherein a frequency converter connecting base is installed at the top of the motor shell, a frequency converter and a wiring terminal are installed in the frequency converter connecting base, and the frequency converter is movably and detachably connected with the frequency converter connecting base; a hole communicated with the interior of the motor shell is formed in the bottom of the wiring terminal; a three-phase connecting wire of a stator winding in the motor casing is connected with one end of a wiring terminal, and the other end of the wiring terminal is connected with a frequency converter. The integrated structure of the permanent magnet motor and the frequency converter can be realized by arranging the threaded holes in the frequency converter connecting seat; the frequency converter and the permanent magnet motor can be conveniently separated by installing the wiring terminal on the frequency converter connecting base, and the frequency converter and the permanent magnet motor work independently.

Description

technical field [0001] The invention relates to mine permanent magnet synchronous motor technology, in particular to a detachable mine permanent magnet synchronous frequency conversion and speed regulation integrated machine motor structure. Background technique [0002] my country is a big coal country, and the output of coal mines ranks first in the world. The coal industry is the leading industry of primary energy in my country, so the development of mining equipment for the coal industry is of great significance for promoting the development of coal mining technology and equipment in my country. In my country, coal mining is dominated by underground workers, with limited underground space, humid environment, high risk factor, and long operating hours. Therefore, the motor that provides power for the entire mining process needs to have strict design requirements, high safety and reliability. It plays a key role in the transformation of coal resources. [0003] In the fie...
