This is a ring rotor magnet used for DC brushless motor magnetic encoders, with a single side 8-pole magnetization, which means only one side has strong magnetic strength (using side). The material is injection molded ferrite, made of ferrite magnetic powder and nylon, which is not fragile. The specifications are outer diameter 18mm, inner small hole diameter 2.25mm, and height 3.2mm, suitable for various robots, electrical appliances, and induction devices. There are many similar stock specifications, and there is a wide selection of magnetic poles, Support non-standard customization, welcome to inquire about samples and mass purchase.


Injection molding magnetic temperature characteristics;

The maximum usage temperature varies depending on the magnetic alloy powder and adhesive. For example, Nylon 6 or PPS grade ferrite powder can achieve satisfactory test results at 180 ° C. On the other hand, Nylon 12 will melt over 170 ° C, so it is not recommended to use at temperatures above 150 ° C. Regardless of the type of adhesive used, magnetic materials such as neodymium iron boron grades with a maximum magnetic energy product or intrinsic coercivity of 9500 ohms (760 kiloamperes per meter) will exhibit significant irreversible magnetic losses at temperatures exceeding 120℃.
