Method for setting origin position of high-precision magnetic encoder

The invention provides a method for setting the origin position of a high-precision magnetic encoder. The setting of the origin position needs to include the following parts: a magnetic encoder, a low-voltage DC brush motor, a straight-line motion mechanism, a driving control module and two high-repetition position proximity switches. The method provided by the invention overcomes a problem of lowprecision of the traditional method, in which a travel switch is selected to serve as the origin position of the encoder, of the encoder, and the origin position is enabled to change because the sensing distance of the proximity switch changes along with the temperature when the proximity switch is selected to serve as the origin position of the encoder, so that the magnetic encoder is ensured tostill guarantee very high precision in origin position in different environments and has very high economical efficiency compared with a high-precision absolute encoder. 本发明提供了种高精度磁编码器的原点位置设置方法，原点位置的设置需包含以下几个部分：磁编码器，低压直流有刷电机、
