The Main Noise Source Of The Motor
Noise is a combination of cluttered sounds of various frequencies and intensities, and the nuisances of this nuisance sound to humans are well known. Noise often accompanies vibration, and excessive vibration can damage other equipment. The level of vibration and noise reflects the level of product design and manufacturing, and is an important indicator to …...Read more -
Energy Efficiency Standards for Electric Motors
At present, the countries that formulate motor efficiency standards internationally include the United States, Canada, Mexico, Brazil, Australia and New Zealand. my country has promulgated the energy efficiency standards for electric motors at the beginning of this year, and will be officially implemented on August 1, 2002. Regarding the EU-wide European Motor and Power Electronics …...Read more -
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 -
Comparison Of Soft Start And Traditional Decompression Start Methods
The traditional decompression starting methods of cage motors include star-delta starting, auto-coupling decompression starting, reactor starting, etc. These start-up methods are all hard-starts with stepped decompression, and have obvious disadvantages, that is, secondary inrush current occurs during the start-up process. The difference between soft start and traditional decompression start is as follows. 1.1 No inrush …...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 -
Ways To Extend The Life Of The Motor
If you want to prolong the life of the purchased motor, you should take the following methods in daily operation to achieve the goal. 1. Daily cleaning When the motor is in use, it is easy to enter dust and other powders. Although these dusts have no effect on the coil, they still have a …...Read more
