What is a servo motor for?

Servo motor occupies an important position in the composition of automation equipment. It can convert voltage signal into torque and speed to drive the control object, control speed, and position accuracy is very accurate. The rotor speed of the motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator, and has many characteristics such as small electromechanical time constant, high linearity, and starting voltage, which can convert the received electrical signal. This is further converted into angular displacement or angular velocity output on the motor shaft.


The servo motor is in the range of its rated speed and belongs to the constant torque output. It has a variety of feedback adjustments, which can be used to ensure the running accuracy and output torque of the servo.


1. Medical industry: monitor, slicer, B-ultrasound machine, electrocardiogram (EEG) tester, CT control box, X-ray machine, hemodialysis machine, temperature controller, etc.;


2. Printing industry: printing machine, drying machine, offset printing machine, laser phototypesetting, proofing equipment, rotary machine, automatic punching machine, inkjet printer, folding machine, paper cutter, sewing machine, glue binding machine, automatic feeding Paper gluing machine, automatic tile cherry cardboard (box) production line, computer three-side bag sealing machine, shaftless high-speed offset printing machine, etc.;


3. Machinery industry: machining center, CNC punch, bending machine, assembly equipment, shearing machine, PLC program controller, various types of automobile testing equipment, welding equipment;


4. Food industry: sterilizer, can making machine, homogenizer, labeling machine, flow controller, sealing machine, packaging machine, coffee machine, etc.;


5. Rubber tire industry: steel belt production line, inner lining extrusion line, steel wire calender, double compound extruder, steel cord cutting machine, heavy internal mixer, radial tire wire machine, etc.;


6. Elevator industry: all kinds of elevator door control, floor control.


It can be seen that the function of the servo motor is very powerful, and the application industry is far more than the above. Although servos have advantages over stepper motors in terms of accuracy, speed, stability, timeliness, low frequency characteristics, and overload capacity. As for whether the servo motor is good or the stepping motor is good, the most important thing is to see what industry and what occasion is used. Both have their own characteristics under certain constraints.
