1. GROUP NO :1 PRESENTS MINI PROJECT 3 Ø DOL STARTER S4 EEE Here is where your presentation begins

2. ABSTRACT The single-phase Direct-On-Line (DOL) starter is a crucial component in electric motor control systems. This abstract explores the key aspects of designing and constructing a single-phase DOL starter, emphasizing its role in providing efficient and reliable motor starting. The abstract covers the essential components involved, such as contactors, overload relays, and start/run capacitors, highlighting their functions within the starter circuit. Additionally, it addresses the significance of proper sizing and selection of these components to ensure optimal performance and protection for the single-phase motor. The abstract aims to provide a concise overview of the considerations and steps involved in the creation of a reliable single-phase DOL starter.

3. INTERNAL COMPONENTS CONTACTOR The contactor is an electromagnetically operated switch. OVERLOAD RELAY The overload relay is a protective device that monitors the motor current. CONTACTOR COIL It is usually part of the electromagnetic mechanism within the contactor START STOP BUTTONS These buttons are part of the control circuit. TERMINAL BLOCKS Terminal blocks are used for connecting external power supply lines, motor leads, and control circuit wiring. GROUNDING POINTS These points are used to connect grounding wires.
