Core-Type Transformer

Transformer Turns Ratio

Each winding of a transformer contains a certain number of turns of wire. The turns ratio is defined as the

Transformer Tap changer

Transformer Mutual Induction

If flux lines from the expanding and contracting magnetic field of one coil cut the windings of another nearby coil,

Synchronous Motor Principle

Synchronous Motors

Synchronous motors are like induction motors in that they both have stator windings that produce a rotating magnetic field. Unlike

AC Induction Motor Slip

It is virtually impossible for the rotor of an AC induction motor to turn at the same speed as that

AC Motor Theory

AC motors are widely used to drive machinery for a wide variety of applications. To understand how these motors operate,
