The Reason For The Excessive Load Of The Special Motor For The Fan
The fan is usually composed of three parts: the hood, the motor and the fan blade. The motor is an outer rotor structure. Compared with the inner rotor motor, the outer rotor motor has the advantages of stable structure, good protection, low vibration, low noise and reliable operation. However, due to the long-term high-power and …...Read more -
Explosion-proof Motor Troubleshooting
Explosion-proof motor is a special motor equipment with great danger. Once the explosion-proof surface has rust and rust spots, the contact surface is not in good contact, and harmful media will take the opportunity to enter, corroding the parts and winding insulation in the machine, and once the explosion-proof motor loses explosion-proof performance, the consequences …...Read more -
Several Common Three-phase Asynchronous Motors
Common three-phase motors mainly include: Y series, Y2 series, YE2 series, YEJ series, YX3 series and other three-phase asynchronous motors. The base models mainly include: There are mainly B3, B5, B35, B14 bases, which are the common installation methods of ordinary three-phase asynchronous motors, but what does the horizontal type B3 vertical B5 installation of …...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 Improve The Insulation Quality Of Explosion-proof Motors
Measures to improve the insulation quality of explosion-proof motors include the following aspects 1. Improve the quality of the iron core: At present, the insulation specifications of the explosion-proof motor industry are basically unified. The selection of materials and the design of the insulating structure are not very different from one manufacturer to another. But …...Read more -
Test Method For Motor Heating Up
Micromotor heating test method and matters needing attention 1. Environmental conditions of micro-motors 1. The measurement of the temperature rise of the micro DC motor should be carried out in a room that is not affected by the external temperature. The indoor ambient temperature should be in the range of 5~40 °C. Should the indoor …...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 -
Features Of Y Series Three-phase Asynchronous Motor
Y series is a fully enclosed self-fan cooling cage type three-phase asynchronous motor for general use. The three-phase asynchronous motor stator three-phase winding is the circuit part of the asynchronous motor, which plays a very important role in the operation of the asynchronous motor and is the key component for converting electrical energy into mechanical …...Read more -
Y Series Three-Phase Asynchronous Motor Operation Method
Y series three-phase asynchronous motors should be properly grounded. There is a grounding screw in the bottom right of the junction box. If necessary, the foot of the motor or the flange fixing bolts can be used for grounding. The three-phase asynchronous motor consists of two basic parts: a fixed stator and a rotating rotor. …...Read more -
Maintenance Of Explosion-proof Motors
Explosion-proof motor maintenance work is indispensable when operating with supporting equipment, so what key points should be paid attention to when overhauling explosion-proof motors? 1. Before testing, the parts of the explosion-proof motor should be connected and some installation symbols should be made (the three-phase cables and outgoing wires are marked with yellow, green, and …...Read more
