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

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.
