Description

Technical field [0001] The present invention relates to the field of encoders, and in particular, to an encoder, a motor, and a drive system. Background technique [0002] Encoder technology is widely used in the field of precision instrument control and position detection such as motor speed measurement and position detection, such as absolute encoders can be used to detect the number of rotation of the motor, the rotation direction, and the rotational position. [0003] With the advancement of technology, in order to meet the precision, stability and cost of control systems, the accuracy requirements and reliability requirements of the encoder are getting higher and higher, and the installation conditions of the encoder need to be lower to reduce Installation cost. [0004] In the high-precision absolute value encoder, it is made in two ways to obtain a high-precision absolute value, wherein the absolute value coded is a rough channel, and the relative position code is used as ...
