Soft Starting Of Induction Motor PowerPoint PPT Presentations

Leading supplier of power control devices CD Automation UK is launching a family of low-cost soft starters for small AC induction motors to the UK market.

Induction Motor Scalar Control By Mr.M.Kaliamoorthy Department of Electrical & Electroncis Engineering PSNA College of Engineering and Technology

DOL Motor Starter is the least complex, least expensive and most basic Starting technique. Besides, it really gives the least temperature ascend inside the engine amid start-up of all the beginning techniques.

This device became known as the silicon controlled rectifier (SCR), or in Europe, the Thyristor ; it is the basis on which all soft starting systems are built.

This project is designed to control the speed of a single-phase induction motor by using operating knob, which is commonly used in home automation applications. The main advantage of these motors is their ability to operate from a single-phase power supply

Electric motor demand is expanding as their use expands across several sectors. They can turn electrical energy into mechanical energy.

Most induction motors are started directly on line, but when very large motors are started that way, they cause a disturbance of voltage on the supply lines due to large starting current surges. To limit the starting current surge, large induction motors are started at reduced voltage and then have full supply voltage reconnected when they run up to near rotated speed.
