A direct on line starter, often abbreviated DOL starter is an electrical/electronic circuit composed of electro-mechanical and electronic devices which are employed to start and stop an electric motor. Regardless of the motor type (AC or DC), the types of starters differ depending on the method of starting the motor. A DOL starter connects the motor terminals directly to the power supply. Hence, the motor is subjected to the full voltage of the power supply. Consequently, high starting current flows through the motor.
Electric motors can run in both forward and reverse direction depending on the requirement of the application where it is to be installed, for example, like in a conveyor system which would require moving on both direction of items contained in the conveyor table. When such arrangement is necessary for a certain type of application, then a forward reverse motor controller is applied to the control circuit of the electric motor to achieve this purpose. Again the device required for the possibility of this operation is the magnetic contactor.
This work is on operating forward and reverse of a direct online starter using contactor.

CHAPTER ONE - [ Total Page(s): 1 ]1.0 INTRODUCTION1.1 BACKGROUND OF THE STUDYA motor controller is a device or group of devices that serves to govern in some predetermined manner the performance of an electric motor. A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and faults. A small motor can be started by simply plugging it into an elec ... Continue reading---
