Motor Control Circuit Wiring

S Bharadwaj Reddy
A simple three-phase, 480 volt AC motor-control circuit is shown here, both in pictorial and schematic form. This entire assembly consisting of contactor, overload block, control power transformer, power fuses

Motor Protection Circuits

S Bharadwaj Reddy
An essential component of any high-power motor control circuit is some device to detect a condition of excessive overload and interrupt power to the motor before thermal damage occurs. A

How Motor Star Delta Starter Works ?

S Bharadwaj Reddy
Star-Delta starter is an electrical motor starting device, generally uses in big size motor to overcome high motor currents during starting. Star and Delta means here 2 separate states of

Electrical Switches Principle & Types

S Bharadwaj Reddy
Electromechanical switch – Electromechanical switches have mechanical contacts or relays. These types of switches can control a wider range of current and voltage options. They are not affected by dirt, mist,

Motor Inrush Current Measurements

S Bharadwaj Reddy
Why inrush current important ? Inrush current, sometimes known as starting current or locked rotor current in motors, can be four to 10 times higher than a motor’s running current.

Stepper Motor Working Principle

S Bharadwaj Reddy
Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called “phases”. By energizing each phase in sequence, the motor will

Basic Principles of Electricity

S Bharadwaj Reddy
Electricity Electricity, simply put, is the flow of electric current along a conductor. This electric current takes the form of free electrons that transfer from one atom to the next. Thus,
