Why the Slip never Zero in an Induction Motor?
A rotating magnetic field is produced when the three-phase supply is fed to the stator. The magnetic field travels the air gap length and cuts … Read more
What is Synchronous speed? Relationship between speed and Frequency
Synchronous Speed When three phases which are 120 degree-electrical apart are fed to the stator winding of the induction motor, a rotating magnetic field is … Read more
Slip Speed in an Induction Motor
A rotating magnetic field is produced when three phase supply is fed to stator of an induction motor. The rotating magnetic field has constant magnitude … Read more
Air Gap Power in Induction Motor
Air gap power in an induction motor is the output power of the stator or input power to the rotor. The electrical power fed to … Read more
Why Starting Torque of Squirrel Cage Induction Motor is Low?
The starting torque of an induction motor is very low compared to its rated torque. The torque of an induction motor depends on the rotor … Read more
What is the importance of slip in an induction motor?
The induction motor can’t run if there is no slip. What is a slip of an induction motor? Let us first understand the slip of … Read more
Why does an Induction Motor has Poor Power Factor at NO Load?
The power factor of an induction motor is very low, in the range of 0.1 to 0.3 when the motor runs at no load. There … Read more
