[0002] The servo motor encoder is a sensor installed on the servo motor to measure the magnetic pole position, servo motor angle and speed. According to the physical medium, the servo motor encoder can be divided into photoelectric encoder and magnetoelectric encoder. In addition, the rotary transformer is also a special servo encoder. Basically, the ones used on the market are photoelectric encoders. However, as a rising star, magnetoelectric encoders are reliable, cheap, and anti-pollution. They have the characteristics of being reliable, cheap, and anti-pollution, and they tend to surpass photoelectric encoders.

[0003] The servo motor encoder is a very special encoder that is interconnected with the servo motor. When the servo motor is working, its output shaft drives the internal structure of the servo motor encoder to rotate.

[0004] In the prior art, a conventional encoder is fixedly connected to the servo motor housing by fastening bolts. During use, the servo motor vibrates, causing the fastening bolts to loosen or fall off, thereby causing the encoder to loosen or fall off. In addition, the servo motor output shaft and the inverter input shaft, as well as the servo motor and the encoder housing, are rigidly connected. The servo motor will drive the encoder to vibrate, causing damage to the internal components of the encoder and reducing its service life. Utility Model Content

[0009] Furthermore, the locking mechanisms are provided in four groups, and the locking mechanisms and the limiting mechanisms are arranged in a staggered manner.
