What parameters should be considered when selecting servo motor

What parameters do you select for servo motor? The most important is the speed, power and torque of the motor. Of course, many times we also need to consider the motion accuracy of the motor, and the choice of encoder is also careless. The accuracy of 23-bit multi-turn absolute value encoder is much higher than that of 17-bit multi-turn absolute value encoder. Moreover, the servo motor mostly uses the field bus as the medium of information transmission, and a bus can connect multiple motors to work. At present, the common fieldbus used for servo motors include CANopen, ethercat, Profinet, etc. Considering the installation problem, the base of the motor should also be considered when selecting the servo. The common ones are 42, 57, 60, 80, etc., and the unit is mm. The higher the power of the motor, the larger the base size.
