Modeling Eddy Current Losses in Permanent Magnet Motor Let’s begin with our model geometry. In this example, we have a 3D model of an 18-pole PM motor. To reduce computational efforts and capture the full 3D behavior of the motor, we use sector symmetry and axial mirror symmetry. You can see an animation of the [...]
Determine Strong Magnet Quality NdFeB magnets are popular word products in the market. At present, the demand in China's market is getting bigger and bigger, and the bidding is getting bigger and bigger. Many magnet manufacturers have better competitive advantages in the market. Will reduce the cost by using inferior raw materials. Therefore, when buying [...]
Take you to know how magnets are produced Due to the wide variety of magnets, the usual manufacturing method is to sinter rare earth permanent magnets. For raw materials such as samarium cobalt and neodymium iron boron, sintering is carried out under vacuum or a protective atmosphere, post-treatment and mechanical processing, and the processing components [...]
What are the difficulties when cutting ferrite magnets? A ferrite magnet is a metal oxide having ferromagnetism. In terms of electrical characteristics, ferrite magnets have much higher electrical resistivity than metal and alloy magnetic materials, and also have higher dielectric functions. The magnetic function of the ferrite magnet also exhibits a high magnetic permeability at [...]
Magnet used in Medicine Today we are talking about magnets. With the development of the times, magnets have gradually entered every corner of our lives. But do you know? Magnets not only have good value in industry, but also magical effects on magnets in medical applications. Let's take a look at them together! Analgesia: Magnetic [...]
The Future Development Trend of NdFeB Magnets After the effective control of rare earth NdFeB magnets in the past two years, the price tends to be stable, the rational development and utilization of rare earth minerals are effectively controlled, and the production of rare earth magnet raw materials is gradually stable. The raw material prices [...]
Precautions for Custom Powerful Magnets For those old drivers who have used magnets for many years, the company's engineering has a basic understanding of the characteristics of powerful magnets and the size of the products required magnet, but for some companies that have not used magnets, they don’t understand the powerful magnets. What issues should [...]
Installation Method of Magnetic Mobile Phone Holder AND the influence of mobile phone magnet bracket Magnetic Mobile Phone Holders are increasingly popular with consumers, using magnetic field power to allow the phone to be attached to the holder. Although the bracket is easy to use, many consumers do not know how to use it when [...]
N35 And N52 Magnet In the marketing process, some customers do not understand the meaning of the N35, N52 magnet, then what is the matter? In the market, we talk about the neodymium iron boron magnetism. Actually, there are many material grades in the strong magnetism. The magnetic energy product in each grade is different. [...]
Magnet Can Cure Eye Tremor Recently, an article published in Ophthalmology magazine introduced a case of magnetic implants for the treatment of nystagmus, the first report of the use of implants to control eye movements. Researchers at the University of London and Oxford have implanted a magnetic device into the eye and successfully cured a [...]
Permanent magnet materials, also known as hard magnetic materials, are characterized by high anisotropy field, high coercivity, large hysteresis loop area, large magnetization field required for magnetization to saturation, and strong long-term retention after removal of external magnetic fields. Magnetic. In practice, the permanent magnet material operates in the second quadrant demagnetization portion of the [...]
Absorbing materials overcome NFC / RFID antenna interference problem, soft magnetic materials, absorbing materials In recent years, various new applications based on NFC/RFID technology have ushered in an unprecedented period of rapid growth, especially in the current hot mobile payment market. In 2014, the transaction value reached nearly $325 billion, compared with 2013. Compared with [...]
