Permanent Magnet in Automotive EPS The full English name of EPS is Electronic Power Steering, that is, electronic power steering system, which uses the power generated by the electric motor to assist the driver in power steering. As an important part of the whole vehicle, the steering system is one of the key systems that [...]
Inverter Air Conditioner: a new point of growth for permanent magnet materials Air conditioners that meet the first-class energy efficiency standard can obtain a market access pass. It is expected that inverter air conditioners will experience explosive growth and market penetration will further increase. From July 1, 2020, my country officially began to implement the [...]
Φ Magnetic Flux In the application of magnets, magnetic flux (Magnetic Flux) is an important index to measure the performance of magnets, especially in the fields of motors, audio speakers, etc. The concept of magnetic flux Assuming that in a uniform magnetic field with magnetic induction intensity B, there is a plane with area S [...]
Permanent Magnet Materials in Coreless Motors With the continuous development of science and technology, motor technology is also constantly innovating. Especially in today's industrial field, higher expectations and requirements are constantly put forward for the servo characteristics of motors, and coreless motors have emerged as the times require. Coreless motors are DC permanent magnet servo [...]
Surface Magnetism and Magnetic Flux Remanence, coercive force, intrinsic coercive force and maximum magnetic energy product are the four most common parameters to measure the performance of magnetic materials. In addition, we will often see two other parameters in finished magnets - surface magnetism and magnetic flux (also called magnetic flux). Surface magnetism The simple [...]
Testing Magnetic Field Range with Paperclips Make a holder for a bar magnet. You can make a simple magnet holder using a clothespin and a paper or Styrofoam cup. This method would be suitable for teaching elementary school-age students about magnetic fields. Tape one of the long ends of a clothespin to the bottom of [...]
