Embodiment Construction
[0019] attached by figure 1 , 2 As shown: the encoder is composed of two parts: the ring encoder body I and the acquisition head II with a gap between the ring encoder body I and the corresponding encoder body I. The encoder body I includes a bearing ring 1. The magnetic ring 2 attached to the upper edge of the bearing body 1, and the protective cover 3 arranged outside the ring bearing ring body 1 and the magnetic ring 2 to protect the magnetic ring 2.
[0020] attached by image 3 As shown: the magnetic coil 2 is specially magnetized according to different pulse requirements, and its N and S polarities are alternately arranged along the circumferential surface of the magnetic coil 2, and the number is an even number.
[0021] attached by Figure 4 As shown: the collection head II includes an upper cover 4, a lower cover 5 with a brush head 8 on the end face, a circuit board 6 arranged inside the upper cover 4 and the lower cover 5, and a magnetic induction chip 7 arranged...
