Understanding the difference between watts and volts, as well as amperes (amps) and ohms, is crucial when working with any type of electrical system. Repairing household wiring requires a solid understanding of electrical terms, and it is even a helpful knowledge base to have for everyday living. How many times have you seen a lightbulb…
It is interesting to know that the first A.C. drive (400 HP) based on thyratron cycloconverter-fed WRIM was installed in 1932 by F.E. Alexanderson of General Electric in the Logan Power Station of Pacific Gas and Electric Company. From then industrial drives have evolved rapidly by dedicated effort of many scientists and engineers all over the world…
Servo motor mechanism is used in a large number of applications which are critical in position control. We cannot use DC motor to control a tail of aircraft because controlling a DC motor for accurate positioning is not only difficult but almost impossible. Servo Motor in Robotics One of the most popular servo motor applications is robotic….
A servo motor controller is a circuit that is used to control the position of a servo motor. It is also called as a servo motor driver. A servo motor controller consists of a controller, the servo motor and the power supply unit.Servo motor driver may be used to control a single servo or even a group of…
As we know that any electrical motor can be utilized as servo motor if it is controlled by servomechanism. Likewise, if we control a DC motor by means of servomechanism, it would be referred as DC servo motor. There are different types of DC motor, such shunt wound DC motor, series DC motor, Separately excited DC motor, permanent magnet DC motor, Brushless DC motor etc. Among all mainly separately…
Servo Motor Control For understanding servo motor control let us consider an example of servomotor that we have given a signal to rotate by an angle of 45° and then stop and wait for further instruction. The shaft of the DC motor is coupled with another shaft called output shaft, with the help of gear assembly. This…
Servo Motor Working Principle Before understanding the working principle of servo motor we should understand first the basic of servomechanism.Servomechanism A servo system mainly consists of three basic components – a controlled device, a output sensor, a feedback system.This is an automatic closed loop control system. Here instead of controlling a device by applying the variable input signal, the…
What is Servo Motor? This is nothing but a simple electrical motor, controlled with the help of servomechanism. If the motor as controlled device, associated with servomechanism is DC motor, then it is commonly known DC Servo Motor. If the controlled motor is operated by AC, it is called AC Servo Motor. Servo Motor Theory There are…
Hello Electrical people, you already know about the different types of motors that are available today and in this article, I shall discuss about the various techniques used to stop a DC Motor or to bring it to rest as we cut off the supply. Kindly see that the braking preferred to stop a DC Motor is Electrical Braking and not Mechanical…
The term braking comes from the term brake. We know that brake is an equipment to reduce the speed of any moving or rotating equipment, like vehicles, locomotives. The process of applying brakes can be termed as braking. Now coming to the term or question what is braking. First of all we can classify the…
