(i) Internal construction

From the internal construction point of view, A20B - 2003 - 0310 spindle encoders usually utilise advanced magnetic sensitive resistor chip technology. They are generally equipped with two or three sets of magnetic sensitive resistor chips, which interact with the magnets that provide the bias magnetic field. In a practical installation, the encoder is connected to the spindle via a mechanical structure such as a gear, and when the spindle rotates, it drives the gear to rotate, which in turn causes the magnetic field in which the magnetoresistor chips are located to change. This change in the magnetic field is accurately sensed by the magnetoresistor chip and converted into a corresponding electrical signal output. 

(ii) Working Principle

The working principle is based on magneto-electric induction. When the spindle drives the gear inside the encoder to rotate, the change of the gap between the teeth of the gear will cause the change of the strength of the magnetic field. The sensors inside the encoder, such as the magnetoresistor chip, can keenly capture these magnetic field changes and convert them into sine wave signals. By accurately analysing the frequency, phase and other parameters of these sinusoidal signals, the control system is able to accurately calculate key motion parameters such as the rotational speed of the spindle, the direction of rotation and the current position. For example, in the CNC lathe, A20B-2003-0310 spindle encoder can monitor the spindle rotation status in real time, the information will be fed back to the CNC system, the CNC system according to the feedback data to accurately control the feed rate of the tool and the depth of cut, so as to ensure that the machined parts of the dimensional accuracy and surface quality.
