You can choose to buy a magnetic pole test piece on the Internet or send the magnetic ring to the magnet manufacturer to help you determine it. It should be noted that not every magnet manufacturer has this kind of thing. Generally, the manufacturer of motor magnets will have it. Good to ask first....
The encoder magnetic ring brought to you today is a dual-track magnetic ring. The material is not an injection-molded magnet, but a rubber magnet. The cost will be lower. The number of magnetic poles of the two tracks (magnetic code track) is different. magnetic poles (32 pairs of poles), the inner track has 62 poles (31 pairs of poles)...
Precision magnetized rubber magnetic ring magnet, outer ring 64 poles, inner ring 62 poles, the surface magnetic field strength is about 500-600 gauss, suitable for magnetic encoders, robotic arms, motor Hall induction, automation equipment, etc., cost-effective, can come Customized samples, welcome to inquire about prices and samples from motor customers!...
