Power Factor Improvement & Correction | Power Triangle & Capacitor Banks

The electrical energy is almost exclusively generated, transmitted and distributed in the form of alternating current. Therefore, the question of power factor immediately comes into picture. Most of the loads (e.g. induction motors, arc lamps) are inductive in nature and hence have low lagging power factor. Low power factor is highly undesirable as it causes… Read More »

Gear Motor Types Operating Principle and Applications

What is a Gear Motor?  Gear motor is a special type of electrical motor. The main purpose of gear motor is to produce high torque while using a low horsepower, or low speed, motor output. You can find gear motors in many different applications including in many devices or appliances in your home. Gear motors… Read More »

Brushless motor principle application advantage and diagram

Brushless motor also known as BLDC motor  is a synchronous motor that gets power by a DC electric source. It uses an integrated inverter, which ultimately produces an AC electric signal to drive the motor. British scientist Michael Faraday first experimented with the idea of the electromagnetic induction motor in the early 1800’s. During that… Read More »

DC Motor Function of Each Component Explained

DC motor runs on direct or dc current. On this page we shall understand the function of each component of the motor. In general there are two major parts of any motor i.e. stationary part and moving part. The stationary part is mainly the outer part that houses the field windings and receives the supply also… Read More »

DC Shunt Motor Speed Control

The speed of a dc shunt motor is directly proportional to the back emf and inversely proportional to the flux per pole. DC shunt motors are very useful and important part of any motor application. The motor speed control in dc shunt motor is very crucial because it impacts the use and design of the… Read More »

what is servo motor – working principal & application

To better understand the servo motor let us first see what is the meaning of term “servo”. The term servo is applicable for any system that uses a feedback mechanism in order to control the required situation. The feedback can be in the form of signals from sensors or limit switches or number of revolutions,… Read More »
