Abstract
The utility model relates to an incremental magnetic-sensing coder, which is used to solve the technical problems of the photoelectrical coder such as poor reliability and easy damage at high rotational speed. The utility model is characterized in that: the coder comprises a target gear wheel arranged coaxially on a revolving shaft of a motor. The target gear wheel is provided with a magnetic-sensing resistance sensor whose detection face is directed to the target gear wheel and has a given clearance. The magnetic-sensing resistance sensor is connected with a signal switch card through a connection line. Since the utility model checks and tracks the rotational parameters of the motor through the changes of magnetic field by the magnetic-sensing resistance sensor when the gear wheel is revolving, the utility model is not affected by moisture and pollution, thus substantially improves its reliability. In addition, since the target gear wheel is positioned on the revolving shaft of the motor directly, and other parts are separated from the target gear wheel, rotation speed of the motor will not affect the service life of the coder. Therefore, the utility model can check and track motor with the rotation speed of tens of thousands of rotations per minute, thus enhancing its service life.
