We can supply any size and any shape of step motor magnet depending on your request.Normal size is usually in stock,so we can supply samples in short time.Our factory use high quality raw materials to produce magnets so that step motor magnet has high magnetic force and good temperature resistance.
Step Motor Magnet
1.Component:
Step Motor magnet is a kind of Neodymium magnets.Neodymium magnets are the strongest and most permanent magnets.
Neodymium magnets are actually composed of neodymium, iron and boron. The powdered mixture is pressed under great pressure into molds.The material is then sintered, cooled, and then ground or sliced into the desired shape.Coatings are then applied if required.Finally, the blank magnets are magnetized by exposing them to a very powerful magnetic field.
2.Shape&Grade:Ring,35SH-38SH,40UH
3.Test:
We use gauss meters to measure the magnetic field density at the surface of the magnet. This is referred to as the surface field and is measured in Gauss (or Tesla)
Pull Force Testers are used to test the holding force of a magnet that is in contact with a flat steel plate. Pull forces are measured in pounds (or kilograms).
