How do professionals analyze the price of copper in the later period?
“This round of copper price rise has been promoted by the macro side, but also has the strong support of the fundamentals, but from the technical point of view it does rise too fast, that is to say, the adjustment is more reasonable.” The above industry told reporters that in the long...Read more -
How to choose high speed motor bearings?
Bearing is a key part to support the normal operation of the motor, in addition to the manufacturing process control, the design and configuration of the motor bearing is very important, such as vertical motor and horizontal motor should choose different bearing configurations, different speed re...Read more -
Which is the higher stator or rotor temperature during motor operation?
Temperature rise is a very important performance indicator of motor products, and the temperature rise level of the motor is determined by the temperature of each part of the motor and the environmental conditions. From the Angle of measurement, the temperature measurement of the stator part is r...Read more -
Why some motors use insulated end shield?
One of the reasons for shaft current is that in the manufacture of a motor, due to the uneven magnetoresistance of the stator and rotor along the axial direction of the iron core circumference, the magnetic flux is generated and the rotating shaft is intersected, thus inducing the electromotive f...Read more -
How to reduce motor iron loss?
Method of reducing iron loss in engineering design The most fundamental way is to know the reason for the large iron consumption, whether the magnetic density is high or the frequency is large or the local saturation is too serious and so on. Of course, in accordance with the normal way, on the o...Read more -
Save enough electricity to power a whole country
Improving the energy efficiency of motors and drives sounds good in principle but what does it mean in practice? On July 1st, 2023, the second step of the EU Ecodesign Regulation (EU) 2019/1781 comes into force, setting additional requirements for certain electric motors. The regulation’s first s...Read more -
Why proper cooling is important
Like in many other situations in life, the right level of cool can mean the difference between keeping things running smoothly and suffering a heat-induced breakdown. When an electric motor is in operation, the rotor and stator losses generate heat which must be managed through an appropriate coo...Read more -
From July 2023, the EU will be tightening the requirements for the energy efficiency of electric motors
The final phase of the EU ecodesign regulations, which impose stricter requirements on the energy efficiency of electric motors, comes into force on 1 July 2023. This means that motors between 75 kW and 200 kW sold in the EU must achieve an energy efficiency level equivalent to IE4. The implement...Read more -
Be part of the Energy Efficiency Movement-From ABB
Energy efficiency is not an if, it's a must. It is a simple and impactful solution to mitigate climate change. It's the low-hanging fruit we need to bridge our path to a future where all energy is clean energy. The Energy Efficiency Movement brings together all stakehold...Read more -
A Unified Approach for the Commissioning of Synchronous Reluctance Motor Drives
This paper presents a unified procedure for commissioning synchronous reluctance motor drives based on a fast sequence of targeted feedings using the drive inverter. The method requires measuring the values of the phase currents and their derivatives by time-based samplings with still rotor and s...Read more -
How to prevent motor bearing damage?
Ensuring proper lubrication and maintenance of bearings is very important to prevent motor damage and subsequent electrical failure. Here are some key points to consider: 1. Regular bearing testing: Implement a regular testing and inspection program to identify potential bearing problems. This in...Read more -
Characteristics of high efficiency motor
First of all, it is necessary to start with the identification of the motor nameplate, identify the energy efficiency level of the motor, and the corresponding implementation standards, the version of the standard must be the current effective version, the motor energy efficiency can not be lower...Read more
