Wasi Ullah University of Engineering & Technology Peshawar (Bannu Campus) Outlines • Introduction • Problem statement • Objectives • Methodology • Project Timeline • Conclusion • References Introduction • Starting the induction motor is the most important step. • The three Phase induction motor during the initial starting condition draws up much higher current than its capacity and the motor instantly reaches the full speed. • The project is proposed to provide a soft and smooth start to a 3phase induction motor. Cont…. • The induction motor should start smoothly and gradually catch up the speed for a safer operation. • Silcon Controlled Rectifier (SCR) based electronic ease is proposed. • This results in a mechanical jerk and high electrical stress on the windings of the motor which may cause damage. Problem statement Problems associated with start of 3-phase induction motor are • High starting current • Voltage drop • More power loses Objectives • To reduce the high current drawn in the start of induction motor. • To reduce power loss associated with high current. • Will cause reduction in voltage drop. 3-Phase Induction motor • Working on electromagnetic induction • Consist of two parts • Stator and rotor • Fig https://www.electrical4u.com/working-principle-ofthree-phase-induction-motor/ Silicon control rectifier (SCR) • Three terminal device • Current controlling device • Three mode of operation Methodology • Initiated with literature survey • Simulation and Analysis • Hardware Implementation • Result Analysis • Technical Writing Project Timeline Work plan Month Year Month Year Month Year Month Year Month Year Project October Proposal and 2019 Selection Existing Methods Study Simulation And Analysis Hardware Implementat ion Results NovemberDecember 2019 JanuaryFebruary 2020 March 2020 April 2020 Month Year CONCLUSION • The Soft starting method requires a small starting current to generate a small starting torque. • it provides a smooth startup without any jerks along with a controlled acceleration.
