Advantages and Disadvantages of Induction Motor
There are some of the advantages of induction motors compared to DC motors and synchronous motors. We will also discuss disadvantages of induction motors compared 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 !!!
What is no load Current of Induction Motor?
The current drawn by the induction motor when it is not coupled to the driven equipment is called the no-load current of the motor. The
Why Three Phase Induction Motor Self-Starting?
When a three-phase supply is fed to the stator of an induction motor, the stator draws current from the 3-phase supply, which produces the magnetic
Dispersion Coefficient of Induction Motor
The power factor and dispersion coefficient of an induction motor have a relationship. The smaller the dispersion coefficient, the better the power factor. Power factor
Why an Induction Motor is almost constant Speed Motor?
At no load the speed is closest to its synchronous speed. This running speed reduces further when loaded towards its full load capacity, to about 5% for a moderately rated machine tojust more than 5% for smaller rated machine.
Why slip ring induction motor is not started with its slip ring short circuited?
The rotor of the slip ring induction motor is connected to the external resistances. When the motor is started, the total external resistance gets added
Why the rotor winding of three phase wound rotor induction motor is star connected?
The stator can either have a star or delta connection. Many motors have a winding scheme and coils with six connections that connect the windings
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
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
