Industrial Motor Control Using Contactors
Motor contactors are large, high-current rated electromechanical relays. These are special relays in the sense that, they have heavy duty contacts that can handle the motor’s inrush current over many start and stop cycles. The contactor is actuated by an electromagnetic solenoid (coil) which pulls the contacts closed when energized. They also have an arc-suppressing…

Types of AC Motors
Classification of AC Motors The AC motors works by rotating the stator field, they make use of the natural alternating nature of the AC wave to turn the field coils on and off sequentially. Generally, AC motors can be classified into two groups: single-phase and polyphase, with each group being further subdivided into induction and…

The Essential Components of An Electric Drive
Power electronics deals with the applications of solid-state electronics for the control and conversion of electric power. The conversion techniques require switching power semiconductor devices ON and OFF. The block diagram below shows the essential components of an electric drive controlled by a power semiconductor converter. The converter regulates the flow of power from the…
