8LS46.R0045D000-0 B&R 补助马达间接变速装置

8LS46.R0045D000-0是一款伺服电机 ，伺服电机（servo motor）是指在伺服系统中控制机械元件运转的发动机，是一种补助马达间接变速装置。其作用是将电压信号转化为转矩和转速以驱动控制对象，控制速度，位置精度非常准确。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。

伺服电机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。

交流伺服电机的工作原理是，伺服电机内部的转子是永磁铁，驱动器控制的U/V/W三相电形成电磁场，转子在此磁场的作用下转动，同时电机自带的编码器反馈信号给驱动器，驱动器根据反馈值与目标值进行比较，调整转子转动的角度。伺服电机的精度决定于编码器的精度（线数）。

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。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。大惯量，最高转动速度低，且随着功率增大而快速降低。

总的来说，伺服电机8LS46.R0045D000-0具有高精度、高速度、高效率、高可靠性等特点，广泛应用于各种自动化控制系统中，如机器人、数控机床、印刷机械、包装机械、纺织机械等领域。

8LS46.R0045D000-0 is a servo motor, and servo motor refers to the engine that controls the operation of mechanical components in the servo system, which is a supplementary motor indirect transmission device. Its role is to convert the voltage signal into torque and speed to drive the control object, control the speed, and the position accuracy is very accurate. Servo motor rotor speed is controlled by the input signal, and can react quickly, in the automatic control system, used as an executive component, and has a small electromechanical time constant, high linearity characteristics, the received electrical signal can be converted into the angular displacement or angular speed output on the motor shaft.

Servo motor is divided into DC and AC servo motor two categories, its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases with the increase of torque.

The working principle of AC servo motor is that the rotor inside the servo motor is a permanent magnet, the U/V/W three-phase electricity controlled by the driver forms an electromagnetic field, the rotor rotates under the action of this magnetic field, and the encoder of the motor comes with a feedback signal to the driver, the driver according to the feedback value compared with the target value, adjust the rotor rotation Angle. The accuracy of the servo motor is determined by the accuracy of the encoder (number of lines).

A servo mechanism is an automatic control system that enables the controlled output of an object, such as its position, orientation, and state, to follow any change in the input target (or given value). Brush motor has low cost, simple structure, large starting torque, wide speed regulation range, easy control, and needs maintenance, but the maintenance is not convenient (change the carbon brush), electromagnetic interference, and the environment is required. Large inertia, low maximum rotational speed, and rapidly reduced with the increase of power.

In general, the servo motor 8LS46.R0045D000-0 has the characteristics of high precision, high speed, high efficiency and high reliability, and is widely used in various automatic control systems, such as robots, CNC machine tools, printing machinery, packaging machinery, textile machinery and other fields.
