Do the implementation rules for energy efficiency labels corresponding to the GB30253 standard need to be revised?
After the release and implementation of the standard 30253-2013 “Energy Efficiency Limit Values and Energy Efficiency Grades for Permanent Magnet Synchronous Motors”, on April 22, 2020, the “Catalogue of Products Implementing Energy Efficiency Labeling in the People’s Re...Read more -
Sealed bearings, what problems will be encountered in the application of motor products?
According to the actual motor design, sealed bearings are used for small-sized motors, and the motor end cover has the dual functions of bearing chamber and bearing outer cover, thus eliminating the need for inner bearing cover, making the motor structure relatively simple, and naturally reducing...Read more -
Steps and points for replacing motor bearings
Bearings are key components in motors, responsible for supporting the rotating parts, reducing friction, and ensuring efficient operation of the motor. Damage to the bearings can lead to reduced motor efficiency or even more serious failures. Therefore, timely replacement of damaged bearings is e...Read more -
Why does the motor shaft breakage problem occur?
Any problem with a product is likely to be related to manufacturing or use. For example, the motor shaft breakage problem: On the one hand, the motor manufacturer will take necessary measures in the shaft design and manufacturing process, but whether the designed motor matches the operating condi...Read more -
Measures to eliminate electromagnetic interference
According to the basic principles of electromagnetics, the formation of electromagnetic interference ( EMI ) requires three elements: electromagnetic interference source, electromagnetic interference path, and system sensitive to electromagnetic interference. To prevent interference, hardware and...Read more -
Check the contents of grounding of electrical equipment
1. Check whether the connecting bolts are loose or rusted. 2. Check the corrosion of the grounding wire and grounding body below the ground, and whether they are desoldered. 3. Check whether the grounding wire is damaged, broken, corroded, etc. For the overhead power lines including the neutral l...Read more -
Advantages of cylindrical roller bearings in electric motor bearing arrangements
In the motor bearing configuration, cylindrical roller bearings are selected for working conditions with large radial loads. The cylindrical rollers in this type of bearings are in line contact with the raceway, and can withstand large radial loads. They are suitable for bearing heavy loads and i...Read more -
How to configure angular contact ball bearings more reasonably for motors?
For vertical motors that objectively have axial force, angular contact ball bearings are mostly used, that is, the axial load-bearing capacity of the bearing body is used to balance the downward axial force generated by the deadweight of the vertical motor rotor. In the structural design of the m...Read more -
Why do new energy vehicles choose these two types of motors?
In the era of new energy, power consumption and battery life have become indicators for manufacturers to demonstrate their strength. Fuel vehicles are less likely to have range anxiety due to the advantages of high energy density and fast recharging speed of fossil fuels, and they are matched wit...Read more -
Why does the motor lead wire heat up?
As an important component of the electrical part of the motor product, the lead wire of the motor involves electrical insulation and conductivity issues. In theory, as long as it is selected and installed according to the standard current density, the lead wire part will not have heating problems...Read more -
B3740S brushless motor for fascia gun
Fascia Gun, full name of muscle fascia relaxation massage gun (English name Fascia Gun), is used for high-frequency percussion therapy for fascia relaxation. After fitness or exercise, the sympathetic nerves are overexcited, causing the muscles to be too tense when static, resulting in fascia adh...Read more -
Micro reduction motor manufacturers talk about why gear reducers break
Micro reduction motor manufacturers talk about why gear reducers break When the gear reducer is used for a long time, it will also cause vibration or noise problems, which also indicates that the components of the gear reducer are broken. The following analyzes the causes of gear re...Read more
