Why Induction Motor is called Rotating Transformer?
Induction motor as a rotating transformer: The rotor of the squirrel cage induction motor is short-circuited by end rings. When a three-phase supply is fed to
Induction Motor
About 98 % of the motors used in the world is induction motor. The induction motor is simple in construction. It is robust,rugged and reliable motor. All the posts written about induction motor is useful for engineering students and the professional engineers working in the field. I tried to cover every practical aspects in the posts. Happy Readings !!!
Why Induction Motor is called Asynchronous Motor?
An induction motor is called an asynchronous motor because the actual speed of the motor is not equal to the synchronous speed of the motor. The synchronous
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
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
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
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
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
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
Why Induction Motor Has Poor Power Factor at No Load
Induction motors have a low power factor at no load because they draw a large magnetizing current to create the magnetic field, while the actual
Deep Bar Double Cage Induction Motor: Construction, Working & Speed-Torque Analysis
