Servo drives are a category of drives that are otherwise called «automatic performers». They receive information about the value of a certain parameter at the input in real time and support it at the output of the executive body. Such drives are used for high-precision movement of mechanisms when performing technological operations. They are installed on numerically controlled machines, printing and sewing equipment, and in robotics.
Design features of servo drives
The design of servos includes:
- electric motor with gearbox — serves to transform electrical energy into the energy of mechanical movement;
- feedback sensor — converts shaft rotation into an electrical signal;
- drive control board — is responsible for data processing, based on the results of which it sends a signal to turn the electric motor on or off;
- output shaft — the part of the gearbox that extends beyond the housing and is driven by control signals;
- output cable — used to connect the drive to the power source.
What are the main parameters taken into account when choosing a servo drive?
In the online store catalog STEMAG GROUP servos of various functionality are presented. How much a servo drive costs depends on its main characteristics:
- torque — characterizes the mass of the load that the drive can hold at rest at a certain length of the lever;
- rotation speed — shows the time during which the shaft rotates 60°;
- form factor — characterizes the size and weight of the servo drive; conventionally, according to this parameter, drives are divided into micro, standard and large;
- internal interface — analog or digital;
- The material from which the gears are made is polymers, carbon, steel.
