Servo motor is a kind of motor, in the composition of automation equipment occupies an important position, its role is:
Servo motor can be converted into voltage signals for the torque and speed in order to drive the control object, you can control the speed, positional accuracy is very accurate. Motor rotor speed is controlled by the input signal, and can respond quickly, in the automatic control system, used as an executive element, and has a small electromechanical time constant, high linearity, starting voltage and other characteristics, can be converted to the received electrical signal into an angular displacement on the motor shaft or angular velocity output.
Compared to ordinary motors, servo motor response speed, in point-to-point fast positioning of the motion occasions, servo control technology can provide large torque output, making the system has a very high dynamic response, greatly exceeding the motor.
Two, servo motors are mainly used in which industries
Servo motor running accuracy and output torque of high precision, mainly used in the process accuracy, processing efficiency and reliability of the work of relatively high requirements of the equipment, such as:
1, the machinery industry: machining centers, CNC punching machines, bending machines, shearing machines, PLC program controllers, the various automotive testing equipment, assembly equipment, welding equipment.
2, printing industry: sun board machine, printing machine, offset printing machine, rotary machine, laser phototypesetting, proofing equipment, automatic punching machine, airbrush; folding machine, paper cutter, locking machine stapling machine, automatic tile fern cardboard (box) production line, automatic paper feeder gluing machine, computerized three-side sealing bagging machine, shaftless high-speed offset printing machine, etc..
3, the medical industry: monitor, ultrasound machine, CT control box, electrocardiogram (electroencephalogram) tester, X-ray machine, slicer, hemodialysis machine, temperature control instrument.
4, food industry: sterilizer, homogenizer, labeling machine, canning machine, flow controller, sealing machine, packaging machine, coffee machine and so on.
5, rubber tire industry: steel wire belt bundle layer production line, liner layer extrusion line, steel wire calender, double composite extruder, steel cord fabric cutting machine, heavy-duty dense refining machine, radial tire steel wire machine, etc.
6, elevator industry: all kinds of elevator door control, floor control.
Three, the servo motor is good
Servo motor is a better kind of motor, it has high precision, can realize the position, speed and torque closed-loop control, no out-of-step problem, high speed performance, overload resistance, etc., and basically there is no disadvantage, the main disadvantage is not all waterproof or oil-proof, in the water or oil droplets will be attacked by the use of the premises is not very Convenience.
