Description

Technical Field

[0001] The utility model relates to the technical field of electric motors, and more particularly to a three-phase asynchronous motor which is easy to assemble and disassemble. Background Art

[0002] A three-phase asynchronous motor primarily consists of a stator (stationary) and a rotor (rotating), with a certain air gap between them. Its operating principle is based on the interaction between the stator's rotating magnetic field (the resultant magnetic field generated by the three-phase currents in the stator windings) and the rotor's current (the current in the rotor windings). Three-phase asynchronous motors are a leading category of small and medium-sized motors. As one of the most important power devices, they convert electrical energy into mechanical energy to drive various types of machinery. They offer advantages such as simple structure, reliable operation, and low cost. They are widely used in industries such as chemical, textile, metallurgy, construction, agricultural machinery, mining, and light industry. They serve as the power source for a wide range of major machinery, including fans, pumps, compressors, machine tools, printing presses, papermaking machines, textile machinery, rolling mills, air conditioners, urban subways, light rail transit, and electric mining vehicles.

[0003] The outer shell of the existing motor is an integral whole. When the shell needs to be disassembled, the cover on one side needs to be disassembled first before the shell can be disassembled. In addition, the existing cover and the shell are connected by multiple bolts. When the shell needs to be disassembled, tools need to be used to disassemble the multiple bolts, which is inconvenient to operate. For this reason, we propose a three-phase asynchronous motor that is easy to disassemble and assemble. Utility Model Content

[0021] Among them, bases 20 are fixed on both sides of the bottom of the lower shell 2, and mounting holes 21 are opened on both sides of the base 20, so that the base 20 can be easily installed and fixed through the mounting holes 21.
