<div> Server System<br /> The servo system is a feedback control system used to accurately follow or reproduce a certain process. It consists of a controller, a power drive device, a feedback device and a motor. Its main task is to amplify, transform and regulate the power according to the requirements of the control command, so that the torque, speed and position output by the drive device can be controlled flexibly and conveniently.<br /> Servo systems are divided into open loop, closed loop and semi-closed loop types according to the control mode. Its main functions are: to control high-power loads with low-power command signals; in the absence of mechanical connection, the input shaft controls the output shaft located far away to achieve long-distance synchronous transmission; to enable the output mechanical displacement to accurately track the electrical Signal etc. Servo systems were initially used in national defense industries, such as artillery control, automatic driving of ships and aircraft, and missile launches. Later, they were gradually extended to many sectors of the national economy, such as automatic machine tools, wireless tracking control, etc.<br /> Main Effect<br /> 1. Use low-power command signals to control high-power loads;<br /> 2. In the absence of mechanical connection, the input shaft controls the output shaft located far away to achieve long-distance synchronous transmission;<br /> 3. Enable the output mechanical displacement to accurately track electrical signals, such as recording and indicating instruments, etc.<br /> Performance Requirements<br /> The basic requirements for servo systems are stability, accuracy and fast response.<br /> Good stability: After the disturbance acting on the system disappears, the system can return to its original stable state or the system can reach a new stable operating state under the action of input command signals. Under the influence of given input or external interference can reach a new or return to the original equilibrium state after a short adjustment process;<br /> High accuracy: The accuracy of the servo system refers to the accuracy with which the output quantity can follow the input quantity. As a precision machining CNC machine tool, the required positioning accuracy or contour processing accuracy is usually relatively high, and the allowable deviation is generally between 0.01 ~ 0.00lmm;<br /> Good fast response: It has two meanings. One refers to how quickly the output changes with the input command signal during the dynamic response process, and the second refers to how quickly the dynamic response process ends. Fast responsiveness is one of the signs of the dynamic quality of the servo system, that is, the response to the tracking command signal must be fast. On the one hand, the transition process time is required to be short, generally within 200ms, or even less than tens of milliseconds; on the other hand, in order to meet the overshoot The requirement is that the front edge of the transition process must be steep, that is, the rising rate must be large.<br /> High energy saving: Due to the rapid response of the servo system, the injection molding machine can quickly adjust the supply according to its own needs, which can effectively improve the utilization rate of the injection molding machine's electric energy, thereby achieving effective energy saving.<br /> Can servo motors use slip rings?<br /> This can be used. Servo motor refers to the engine that controls the operation of mechanical components in the servo system. It is an indirect transmission device that assists the motor. Servo motors can control speed and position accuracy very accurately, and can convert voltage signals into torque and rotational speed to drive control objects. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant, high linearity, starting voltage, etc. It can convert the received electrical signal Converted into angular displacement or angular velocity output on the motor shaft. They are divided into two categories: DC and AC servo motors. Their main feature is that there is no rotation when the signal voltage is zero, and the rotational speed decreases at a constant speed as the torque increases.</div>
