Magnetic encoders,also known as magnetic encoders,have onlyrecently gained widespread use.They utilize the principle ofmagnetic field measurement and consist of a magnetic fieldgenerator and magnetic sensors.Essentally,a magnet is mountedon the motor shaft,rotating with the shaft.A circuit board with amagnetic field sensing chip in the center is mounted on the rearend cover.This chip measures the angle of the magnetic field,thereby determining the motor shafts rotational angle and angularvelocity.
