Reversing Starter For Motors

Abstract

This project profile envisages the production of Reversing Starter. Starter is used for starting and stopping of motor. The starter in addition to starting and stopping, protects the motor from over voltage, over current, short circuit, single facing etc. The Reversing Starter is a special type of push button starter wherein addition to starting/ stopping of motors the director of rotation of a three phase induction motor can be done by inter changing the connection of any two terminals of the supplies which is done through two separate contactors, one for forward and other for reverse operation to prevent both the contactors getting energized simultaneously and causing short circuit some preventing methods called inter locking methods are employed. Inter locking is done by connecting closed auxiliary contact of forward contactor in series with the coil of the reverse contactor and vice versa. When push button for forward is pressed motor rotates in forward direction and the motor direction is reversed by pressing reverse direction push button.
