How does servo motor understand? What is a servo motor? What about motors? What's different about servo motors and other motors?
Popular speaking/machine is composed of actuator power transmission control system, power supply and control system can be used motor used in the control system is called servo motor (such as: adjust the actuator position servo motor don't need too high, but the rotation must be accurate corner stop position strictly controlled signal command (such as step motor) is not motor as power, so long as can turn
Servo motor (servo motor) is the engine that controls the operation of mechanical components in servo systems. The servo motor can control the speed, the position precision is very accurate, can convert voltage signal to torque and speed to drive the control object. Servo motor rotor speed controlled by the input signal, and can be rapid response, in the automatic control system, is used as actuators, and has a small electromechanical time constant, high linearity, initiating character such as voltage, can convert the received electrical signal to the motor shaft angular displacement or angular velocity on output. Divided into two major categories of dc and ac servo motor, its main characteristic is, when the signal voltage is zero no rotation, speed decreases with the increase of torque and uniform.
Servo is to make the object's position, orientation, and state is accused of output can follow the input target given value (or) any change of the automatic control system, to put it bluntly, is a precision closed-loop control system. Dc motor and ac motor. For the daily application, it is mainly the ordinary motor, the frequency conversion motor, the servo motor. The servo motor is characterized by the power line and the signal line. It has its own encoder and so on, and given a speed, it will be running at that speed. And because there is an encoder inside, it knows how many circles it has turned, and it can precisely stop the motor from being in a certain position. So in accurate control, the servo motor is chosen. It can be used for constant speed control, constant torque control, positioning control and so on.
Stepper motor, (poor and servo motor is good, and the servo motor, stepping motor without encoder, the encoder is equivalent to the whip of slave owners, that is to say, the servo is bad control of the slave owners, refuses to play, so more accurate, and step by step is a kind-hearted slave owners, do work sometimes can not stem, so it is possible to control) is not allowed Three-phase asynchronous motor Three phases, ABC, three phase electricity, asynchronous, which means that there is an unsynchronized link, the process of making the process Three phase synchronous motor Three phase, and ABC, three-phase electricity, synchronization, when electromagnetic transformation that is to say, are synchronous, compared with the three-phase asynchronous motor, this process is more complex, so not commonly used. There are other things to say
The servo motor, servo motor) is transliterated, servo means slaves, let out he put chicken, chicken let him to the west to the west, have to listen to control, or kill! The servo motor is the same motor as the slave, its rotational speed, torque, and the number of revolutions is the arrangement of the controller. The electric motors are divided into many kinds, and the dc is communicated by voltage. According to the characteristic of operation Servo, Stepper motor,
