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), around the disk, the pole alignment between the inner and outer tracks is constantly changing.
When the encoder is working, the 2 magnetic field sensors located on the readhead will generate a sinusoidal signal when crossing the N and S stages, respectively. The phase shift between these two signals is unique for each position around the disk, The readhead converts this analog phase shift into digital signals, each of which corresponds to a unique rotational position on the ring.
To purchase encoder multi-pole magnetic rings, welcome to contact Courage motor magnet manufacturer, our company can provide various types of encoder magnet magnetic rings, a variety of magnetic materials to choose from, and can provide low to high precision as required, As well as different sizes of shapes, magnetic pole spacing, etc., encoder manufacturers are welcome to consult.
