What is the Starting of Three Phase Induction Motor ?
Three phase induction motor definition
A three-phase induction motor is a type of motor that operates with a three-phase power supply and a three-phase stator winding.
Rotating magnetic field
The stator windings are arranged 120 degrees apart to generate a rotating magnetic field that induces a current in the rotor.
Slip speed
The slip speed is the difference between the synchronous speed of the stator magnetic field and the rotor speed to ensure that the motor does not run at the synchronous speed.
Starting current and voltage drop
High starting currents can cause significant voltage drops that, if not managed, can affect motor performance.
Starting method of three-phase induction motor
Different methods, such as DOL, star triangulator and automatic transformer starter, are used to reduce the starting current and ensure smooth operation of the motor.
