Electric DC Motors Principle Of Operation & Types

Construction of dc motor

First of all we should understand the concept of electric DC motors, an electric motor is a machine that converts electrical energy into mechanical energy. Most of the electric motors operate through the interaction between electric motor’s magnetic field and winding currents to generate force within the motor. In certain …

Power & Voltage Distribution Systems – Components Introduction

Distributions systems represent an important parts in the electrical grids and for this reasons the electrical generation & distribution companies delicate approximately 40% of the capital investment for distribution systems while the remaining is given to generation and transmission (40% generation & 20% transmission). The power distribution system is particularly …

Introduction of Distribution Electrical Transformers – How Transformer Works?

In general understanding electrical distribution transformers are used to reduce primary system voltages (which is normally 2.4-34.5kV) to the level of utilization voltages i.e. 120- 600V. International electrotechnical commission standards do not distinguish between distribution electrical transformers and power transformer. They are all power electrical transformers in the sense that …

Ideal Transformer Equations

An ideal transformer is a theoretical, linear transformer that is lossless and perfectly coupled; that is, there are no energy losses and flux is completely confined within the magnetic core. Perfect coupling implies infinitely high core magnetic permeability and winding inductance and zero net magneto-motive force. Ideal transformer equations By Faraday’s …
