Magnetic encoder (vernier code) for humanoid robot joints
① Absolute position calculation:
——Calculation of absolute angle and position using dual code channels
② Small size and easy integration:
——The chip occupies a small board area and is easy to integrate on the main control board
③ Magnetic ring size is limited:
——In general, the number of magnetic pole pairs is less than 32, and the outer diameter of the magnetic ring is less than 42 mm (angle redundancy 0.36 °)
——Under precise conditions, the magnetic pole pairs can reach up to 64 pairs, and the outer diameter of the magnetic ring is less than 84 mm (angle redundancy of 0.09 °)
