Transformer Connections Explained: Star-Star, Delta-Delta, Star-Delta, Delta-Star Transformers are the backbone of modern power systems, enabling efficient transmission and distribution of electrical energy.…
Electrical machines rely on armature windings to convert energy between electrical and mechanical forms. In DC machines , the armature winding sits on the rotor and interacts with the stationary magnetic field to i…
When a DC motor starts from rest, its speed is zero. At this moment, the back electromotive force (back EMF) is also zero. If the motor is connected directly to the supply mains in this condition, a very high current f…
Introduction In many modern applications, electric motors are not just required to rotate in one direction or operate in one mode. They often need to: Run forward and reverse Act as a motor (convert electrical energy to mechanica…
What is a DC Circuit? A DC circuit is a closed path where direct current flows from a voltage source (like a battery or DC power supply) through one or more electrical components. The way the components are connected — in se…
