## Magnetization

A direct current i flowing in a closed circuit limited by a small area S Δ is called a magnetic dipole (Fig. 1.4). It has its own magnetic field, the parameters of which are determined by the magnitude of the current and the diameter of the circuit. Magnetization Fig. 1.4 A magnetic dipole can be …

## Magnetic flux

Magnetic flux is the flux of the magnetic induction vector through any surface. It is defined as where is the vector corresponding to the elementary area ds of the surface S and directed normally with respect to it (Fig. 1.3, a) ds If the magnetic induction is normal to the surface ds, then those. magnetic …

## Magnetic field and magnetic induction

The conversion of electrical energy in induction-type machines is carried out using electromagnetic fields. A magnetic field is called space, the state and properties of which are determined by the movement of electric charges. Two manifestations are inherent in a magnetic field: force action on moving electric charges and excitation of an electric field when …

## Considerations for a High Performance Capacitor

High Performance Capacitor are discusse to very complex level. If you need some other high voltage articles visit here. Basic Considerations of High Performance Capacitor Dissipation Factor (DF) Quality Factor (Q) Equivalent Series Resistance (ESR) The dissipation factor (DF), the quality factor (Q) and the equivalent series resistance (ESR) are important parameters of high-performance capacitors. …

## Fundamentals of designing a machine

The fundamentals of machine design is done before desgn a machine and it is important part. Also It need to be consider all considerations about all factors. Symbols – Fundamentals of machine design n = speed in revolution per second(rps) ns = synchronous speed(rps) p = number of poles P = number of pole pairs …

## Electromechnical Energy Conversion

Electromechnical Energy Conversion are essential to understand. For more visit here. Every electrical machine makes use of magnetic field energy as an intermediate form of energy in the process of electrical-mechanical energy conversion. i.e energy conversion takes place from electrical energy energy to magnetic field energy to mechanical energy (in case of motor) or vice …
