Let us first understand what is a synchronous motor basically, it is an induction motor that rotates at a synchronous speed. Here again, the question arises what is synchronous speed, now the synchronous speed is the speed at which the magnetic field rotates, depending on the frequency. From the formula Ns=120f/p, we know synchronous speed depends on frequency and number of poles (Ns=synchronous speed, f=frequency and p=number of poles). Practically all … [Read more...]
What is an Excitation : Types and Its Working
Excitation, the literal meaning is different in each stream of science and humanity. It is an increased activity of cells/organs in biological science in chemical science it is increased activity of various molecules and so on. In electrical engineering, the magnetic effect of current and its field which is known as excitation and only after an electrical machine gets excited it is ready to perform other functions like rotation/motoring or generation, etc. … [Read more...]
What is an Asynchronous Motor : Construction and Its Working
An asynchronous motor is a most extensively used motor in the industry, It is almost impossible to think of an industry without using this motor, due to its operation at the sub-synchronous speed it is known as an asynchronous motor. Having assumed such an important role it becomes imperative to study it in detail. This article discusses an overview of the asynchronous motor like its definition, working, construction, differences, and applications. What … [Read more...]
What is Three Phase Induction Motor : Construction, Working & Applications
As the name suggests, an induction motor is a combination of induction and motor, induction is influencing or altering in any way an article or object by another article or object without physical contact. The best example being, a magnet that can either attract or repulse without physical contact. The motor is known to be associated with motion. Therefore when we say induction motor it is a rotating device based on the principle of induction. This article … [Read more...]
What is DC Servo Motor : Principle and Its Applications
A DC motor along with servomechanism (closed-loop control system) acts as a servo motor which is basically used as a mechanical transducer in the automation industry. Based on its accurate closed-loop control, it has versatile applications used in many industries. The DC servo motor definition is, a motor that is used in servo systems is known as a servo motor. A servo system is a closed-loop system where the feedback signal (position, velocity, … [Read more...]
What is a Motor Winding : Design and Its Connections
These days human life is completely revolving around machines and technology. Advancement of technology has shown invention for multiple kinds of machines. And an electrical machine is the one which is crucial to transform one form of energy into another form. So, a machine will generate the output when there is a connection between the electric current and the magnetic field and this connection happened through coil windings. Motor windings hold utmost … [Read more...]
What is a Vibrator Motor : Circuit, Types and Its Specifications
Well, you might be well-versed with the word “Vibration”. Mostly we all know what vibration in mobile phones is where it vibrates our mobile when there is a notification or when we receive any call. This is the only scenario that gets into our thought about vibration, but there are many cases where vibration pays attention such as in the compressor rotation in refrigerators, to run the washing machine vibrator. Extending this concept, we need to be clear … [Read more...]
What is Torque Converter : Components and Its Advantages
Several years ago, Twin Disc Clutch Company stepped in with the idea of hydraulic torque converters and its capabilities to change the operational methodologies of logging and dirt-moving machinery and other industrial drives. In 1938, the company got succeeded with its first torque converter and its application as a drilling rig. In the later stages, it has changed the lives of much high-machinery equipment. The torque converter plays a significant role … [Read more...]
Repulsion Motor Working and Its Applications
In the previous articles, we have discussed different kinds of motors. This article discusses an overview of repulsion motor and how its principle helps in rotating a motor. This motor is a special type of 1-phase AC motor and working of this can be done by the repulsion of related poles. The stator in the motor supplies 1-phase AC supply & the rotor circuit will be shorted using carbon brush. The classification of these motors can be done under … [Read more...]
