As for the reasons for motor demagnetization, firstly, the motor cooling fan is abnormal, causing the motor to be high temperature, and the motor is not equipped with a temperature protection device; in addition, the ambient temperature may be too high; and finally, the motor design may be unreasonable.
Why Ndfeb magnet price fluctuates greatly? The main raw materials of NdFeb include rare earths such as praseodymium neodymium, dysprosium iron, terbium metal and pure iron, of which praseodymium neodymium accounts for a large proportion of the price.
How long does the delivery time of Ndfeb magnet take? This is a very specific problem, the delivery date and product performance requirements, specifications, quantity, surface treatment are related, we need to understand the NdFeb magnet production process and processing process, and then to analyze and discuss the delivery time needs how many days?
The magnet test meter magnetic and magnetic flux which is more accurate, or should be based on which parameters as the quality of the magnet or qualified or not
Ndfeb is an alloy composed of praseodymium neodymium, iron and boron, which is one of the most excellent permanent magnet materials at present. It has the advantages of high magnetic energy product, high coercivity and strong corrosion resistance.
In January 2023, praseodymium and neodymium continued a higher price at the end of 2022, and rose to 920,000 yuan/ton before and after the Spring Festival.
What are the precautions for the storage and transportation of magnets?
Factors affecting the magnetic force of Ndfeb magnets.
The operating temperature of ordinary Nd-Fe-B magnets is 80℃-200℃, the upper limit of ordinary materials is 80℃.
The main raw materials of NdFeb permanent magnets are rare earth metal neodymium (Nd) 32%, metallic element iron (Fe) 64% and non-metallic element boron (B) 1% (a small amount of added dysprosium (Dy), ….
Ndfeb permanent magnets with its excellent performance, rich raw materials, reasonable prices are being rapidly developed and widely used. It is mainly used in micro motor, permanent magnet instrument, electronic industry, automobile industry, petrochemical industry, nuclear magnetic resonance device, sensor, audio equipment, magnetic suspension system, magnetic transmission mechanism and magnetic therapy equipment.
At present, there are 5 kinds of magnetic materials on the market to choose from.
If you need to purchase magnets at the factory, in order for a correct quotation and efficiency, we need you to provide the following at the time of inquiry.
