U825T-062E02 SANYO DENKI

U825T-062E 02伺服电机可以控制速度，位置精度非常准确，可以将电压信号转化为转矩和转速以驱动控制对象。伺服电机转子转速受输入信号控制，并能快速反应，在自动控制系统中，用作执行元件，且具有机电时间常数

小、线性度高等特性，可把所收到的电信号转换成电动机轴上的角位移或角速度输出。分为直流和交流伺服电动机两大类，其主要特点是，当信号电压为零时无自转现象，转速随着转矩的增加而匀速下降。

U825T-062E 02伺服系统（servo mechanism）是使物体的位置、方位、状态等输出被控量能够跟随输入目标（或给定值）的任意变化的自动控制系统。伺服主要靠脉冲来定位，基本上可以这样理解，伺服电机接收到1个脉冲，就会旋转1个脉冲对应的角度，从而实现位移，因为，伺服电机本身具备发出脉冲的功能，所以伺服电机每旋转一个角度，都会发出对应数量的脉冲，这样，和伺服电机接受的脉冲形成了呼应，或者叫闭环，如此一来，系统就会知道发了多少脉冲给伺服电机，同时又收了多少脉冲回来，这样，就能够很精确的控制电机的转动，从而实现精确的定位，可以达到0.001mm。直流伺服电机分为有刷和无刷电机。有刷电机成本低，结构简单，启动转矩大，调速范围宽，控制容易，需要维护，但维护不方便（换碳刷），产生电磁干扰，对环境有要求。因此它可以用于对成本敏感的普通工业和民用场合。

U825T-062E 02 servo motor can control the speed, its position accuracy is very accurate, and it can convert the voltage signal into torque and speed to drive the controlled object. The rotor speed of the servo motor is controlled by the input signal, and it can respond quickly. It is used as an executive element in the automatic control system, and has electromechanical time constant.
Small, high linearity, etc., which can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Their main characteristics are that when the signal voltage is zero, there is no rotation phenomenon, and the rotation speed decreases at a constant speed with the increase of torque.
U25T-062E02 servo mechanism is an automatic control system that enables the output controlled variables such as the position, orientation and state of an object to follow the arbitrary changes of the input target (or given value). Servo positioning mainly depends on pulses. Basically, it can be understood that when a servo motor receives a pulse, it will rotate by an angle corresponding to one pulse, thus realizing displacement. Because the servo motor itself has the function of emitting pulses, every time the servo motor rotates by an angle, it will emit a corresponding number of pulses, thus forming an echo with the pulses received by the servo motor, or a closed loop. As a result, the system will know how many pulses are sent to the servo motor and how many are received back at the same time. DC servo motors are divided into brushed and brushless motors. Brush motor has the advantages of low cost, simple structure, large starting torque, wide speed regulation range, easy control, and needs maintenance, but it is inconvenient to maintain (carbon brush replacement), which causes electromagnetic interference and requires the environment. Therefore, it can be used in common industrial and civil occasions which are sensitive to cost.
