SERVOSTAR-310 兩相伺服電動機(jī)的電源斷開，電動機(jī)停止轉(zhuǎn)動

伺服放大器的作用是將多個(gè)輸入信號與反饋信號進(jìn)行綜合并加以放大，SERVOSTAR-310根據(jù)綜合信號極性的不同，輸出相應(yīng)的信號控制伺服電機(jī)正轉(zhuǎn)或反轉(zhuǎn)。當(dāng)輸入信號和反饋信號相平衡時(shí)，伺服電機(jī)停止轉(zhuǎn)動，執(zhí)行機(jī)構(gòu)輸出軸便穩(wěn)定在一定位置上。

伺服放大器主要由前置磁放大器、觸發(fā)器、晶閘管主回路和電源等部分組成。其中，SERVOSTAR-310前置磁放大器把三個(gè)輸入信號和一個(gè)反饋信號綜合為偏差信號，并放大為電壓信號輸出；此輸出電壓同時(shí)經(jīng)觸發(fā)器轉(zhuǎn)換成觸發(fā)脈沖去控制晶閘管主回路的晶閘管導(dǎo)通，從而將交流220V電源加到兩相伺服電機(jī)繞組上，驅(qū)動兩相伺服電動機(jī)轉(zhuǎn)動。當(dāng)輸入信號和與位置反饋電流If相平衡時(shí)，前置磁放大器的輸出電壓約為0，兩觸發(fā)器均無觸發(fā)脈沖輸出，主回路中的晶閘管阻斷，兩相伺服電動機(jī)的電源斷開，電動機(jī)停止轉(zhuǎn)動。

伺服放大器是一種用于放大電信號的電子設(shè)備，SERVOSTAR-310的工作原理是通過負(fù)反饋來控制放大器的增益，從而提高放大器的性能和穩(wěn)定性。

伺服放大器的基本原理是將輸出信號與輸入信號進(jìn)行比較，并根據(jù)比較結(jié)果來調(diào)整放大器的增益，使輸出信號更加穩(wěn)定和準(zhǔn)確。這種負(fù)反饋的控制方式可以有效地抑制放大器的非線性失真、溫度漂移和噪聲等問題，提高放大器的線性度、頻率響應(yīng)和信噪比。

伺服放大器通常由三個(gè)主要部分組成：SERVOSTAR-310輸入級、放大級和輸出級。輸入級負(fù)責(zé)接收輸入信號，并將其放大到適當(dāng)?shù)碾娖健７糯蠹壺?fù)責(zé)進(jìn)一步放大信號，并根據(jù)負(fù)反饋控制電路的要求來調(diào)整增益。輸出級負(fù)責(zé)將放大后的信號輸出到負(fù)載上。

在伺服放大器中，負(fù)反饋控制電路起著至關(guān)重要的作用。它通過將一部分輸出信號與輸入信號進(jìn)行比較，并將比較結(jié)果反饋給放大級，來調(diào)整放大器的增益。具體來說，負(fù)反饋控制電路會將輸出信號與輸入信號進(jìn)行差分運(yùn)算，得到一個(gè)誤差信號。然后，根據(jù)誤差信號的大小和方向，負(fù)反饋控制電路會調(diào)整放大器的增益，使誤差信號趨近于零。這樣，輸出信號就能夠更加準(zhǔn)確地跟隨輸入信號的變化。

伺服放大器廣泛應(yīng)用于各種需要高性能和穩(wěn)定性的電子設(shè)備中，如音頻放大器、功率放大器、運(yùn)算放大器等。在伺服控制系統(tǒng)中，伺服放大器起到非常重要的作用，它負(fù)責(zé)放大控制信號，將其轉(zhuǎn)換成足夠大的電流或電壓，驅(qū)動伺服電機(jī)實(shí)現(xiàn)精準(zhǔn)運(yùn)動。此外，伺服放大器還要實(shí)現(xiàn)反饋信號的比較和誤差放大，以實(shí)現(xiàn)閉環(huán)控制。

總的來說，伺服放大器相當(dāng)于一個(gè)三位式無觸點(diǎn)繼電器，并具有很大的功率放大能力。

The function of the servo amplifier is to synthesize and amplify multiple input signals and feedback signals, and SERVOSTAR-310 outputs corresponding signals to control the servo motor forward or reverse according to the polarity of the integrated signal. When the input signal and the feedback signal are balanced, the servo motor stops rotating, and the output shaft of the actuator is stable in a certain position.

Servo amplifier is mainly composed of pre-magnetic amplifier, trigger, main circuit of thyristor and power supply. The SERVOSTAR-310 preamplifier synthesizes three input signals and one feedback signal into a deviation signal and amplifies the output voltage signal. At the same time, the output voltage is converted into a trigger pulse by a trigger to control the thyristor conduction of the main circuit of the thyristor, so that the AC 220V power supply is added to the winding of the two-phase servo motor to drive the rotation of the two-phase servo motor. When the input signal is balanced with the position feedback current If, the output voltage of the preamplifier is about 0, there is no trigger pulse output of the two triggers, the thyristor in the main loop is blocked, the power supply of the two-phase servo motor is disconnected, and the motor stops rotating.

SERVOSTAR-310 is an electronic device used to amplify electrical signals, and the ServoSTAR-310 works by controlling the gain of the amplifier through negative feedback, thereby improving the performance and stability of the amplifier.

The basic principle of servo amplifier is to compare the output signal with the input signal, and adjust the gain of the amplifier according to the comparison results, so that the output signal is more stable and accurate. This negative feedback control method can effectively suppress the nonlinear distortion, temperature drift and noise of the amplifier, and improve the linearity, frequency response and signal-to-noise ratio of the amplifier.

Servo amplifiers usually consist of three main parts: the SERVOSTAR-310 input stage, the amplifier stage, and the output stage. The input stage is responsible for receiving the input signal and amplifying it to the appropriate level. The amplifier stage is responsible for further amplifying the signal and adjusting the gain according to the requirements of the negative feedback control circuit. The output stage outputs the amplified signal to the load.

In the servo amplifier, the negative feedback control circuit plays a crucial role. It adjusts the gain of the amplifier by comparing a part of the output signal with the input signal and feeding the comparison result back to the amplifier stage. Specifically, the negative feedback control circuit will make a difference between the output signal and the input signal to obtain an error signal. Then, depending on the size and direction of the error signal, the negative feedback control circuit adjusts the gain of the amplifier so that the error signal approaches zero. In this way, the output signal can more accurately follow the changes in the input signal.

Servo amplifiers are widely used in a variety of electronic devices requiring high performance and stability, such as audio amplifiers, power amplifiers, operational amplifiers, etc. In the servo control system, the servo amplifier plays a very important role, which is responsible for amplifying the control signal and converting it into a large enough current or voltage to drive the servo motor to achieve accurate movement. In addition, the servo amplifier also realizes the comparison and error amplification of feedback signals to achieve closed-loop control.

In general, the servo amplifier is equivalent to a three-position contactless relay and has a large power amplification capability.
