Starting and Speed Control Methods of 3-Phase Induction Motors
Introduction A three-phase induction motor has a kind of electrical "resistance" when it starts, which makes it draw too much electrical current when you turn it on. This can be…
Motor Braking | Types, Advantages, and, Applications
Introduction Electric braking provides a more consistent and controlled way to rapidly stop a running motor compared to mechanical braking, which relies on the condition and quality of brake shoes…
Losses and Efficiency Of D.C. Machines
Introduction Electric machines transform energy. Motors change electricity into motion, while generators turn motion into electricity. During this process, energy isn't perfectly converted; some is lost. These losses, like heat,…
D.C. Machine | Types, Losses, and Applications
Introduction DC machines come in two main types: DC motors and DC generators. They're a lot like AC machines but also handle AC currents and voltages. Despite this, they provide…
Incandescent lamps | Types, Advantages, and Applications
Introduction Heat is produced when an electric current is passed through a wire, which raises its temperature. At low temperatures, only heat (I.R. radiations) is produced. At high temperatures, light…
Discharge Lamp | Classification and Characteristics
Discharge Lamp Incandescent lamps have a very low lumens output. Moreover, they give yellow light, which creates strain in our eyes. Discharge lamps have high production and produce a light…
Power Quality | Sources Of Pollution, Need, and Effects
Introduction Power quality refers to how close the electrical voltage is to its ideal state at any given time. High-quality voltage appears as a smooth sine wave with the expected…
Total Quality Management | History, Importance, and Characteristics
Introduction Total Quality Management (TQM) involves comprehensive endeavors across an organization to create a lasting environment where employees consistently enhance their capacity to deliver products and services promptly, which customers…
Energy Conservation | Principle, Importance and Its Benefits
Introduction Energy conservation means using less energy by being smarter with how we use it. This can involve using energy in better ways or changing our habits to use less,…
