How to identify a servo motor without a label?

Servo motor is a popular or popular type of motor nowadays, which is usually connected to other reducers. On the one hand, servo motor has many advantages and advantages in response, accuracy, positioning, reliability, stability, and other aspects of the control system; On the other hand, it can be connected to many types of reducers and servo drives to form its own servo system. If using a servo reducer motor, the precision is relatively high and the clearance is also small. Along with prolonged use and various improper operations, the damage to the servo motor has accelerated. If you encounter a user who has been using it for a long time and the label is missing, how can you determine the model of your servo motor if it is broken? The only thing you can do is to measure and submit various data measurements to the other party's technical team, so that they can make a judgment and determine the model of your servo motor in this form.

The first time you need to measure the size of the output shaft of the servo motor, you can use a vernier caliper to reduce errors;
Next, measure the size of the output flange of the servo motor. A commonly used measuring tape can be used because the specifications of the flange are not so many and are mostly square in shape;
Finally, measure the length of the body, as the body length of each servo motor model is unique, and the size of the body varies with different power levels. So the size of the fuselage is an important parameter.
The above is based on the standard situation in your city, and it cannot be ruled out that some servo motors are customized non-standard, especially imported ones and those from several domestic manufacturers, which may have slight differences in size.
