Disassembly And Assembly Of Three-phase AC Asynchronous Motor
1. Disassemble the asynchronous motor (1) Before disassembling the motor, the connection between the motor and the external electrical connection must be removed, and the phase marks must be made. (2) Disassembly steps a, pulley or coupling; b, front bearing cover; c, front end cover; d, fan cover; e, fan; f, rear bearing cover; g, …...Read more -
Correct Wiring Of Three-phase Asynchronous Motor
Most electricians know that the three-phase stator windings of a three-phase motor have two leads for each phase winding. One end is called the head end, and the other end is called the end. It is stipulated that the head end of the first phase winding is represented by D1 and the end is represented …...Read more -
The Structure Of The Three-phase Asynchronous Motor
To put it simply, the three-phase asynchronous motor is mainly composed of two parts: the stator and the rotor, and the air gap between the stator and the rotor is generally 0.25~2mm, because the air gap is also a part of the magnetic circuit of the motor. When the air gap is large, the reluctance …...Read more -
The Reason For The High Noise Of The Three-phase Asynchronous Motor
When using the frequency converter to drive the three-phase asynchronous motor to run, we often encounter the situation that the three-phase asynchronous motor is noisy. There are only two reasons for motor noise: mechanical and electrical. 1. Mechanical aspects Such as scratching the motor casing, the motor or the cooling fan is damaged, and the …...Read more -
How To Prevent Shaft Breakage Of Three-phase Asynchronous Motor
1. Material and selected material characteristics The motor shaft and shaft extension key are usually 45 steel, and the allowable stress under normal temperature, static load and general working conditions is 186MPa. The rotor and stator of Haocheng Motor’s wound three-phase asynchronous motor are also equipped with three-phase windings and are connected to external varistors …...Read more
