Why can’t an Induction Motor run at synchronous speed?
The induction motor can’t run at synchronous speed because it is not possible to run the motor without load. Even the motor is at no … Read more
Induction Motor
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 … Read more
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 no-load current of the motor. The equivalent … Read more
Why Three Phase Induction Motor Self-Starting?
When three phase supply is fed to the stator of an induction motor, stator draws current from the 3-phase supply which produce the magnetic field. … Read more
Why Insulated Bearing is used for VFD driven Motor?
Insulated bearing for motor is used to prevent the circulating current through the motor bearing. The circulating bearing current can damage the bearing. When we … Read more
Dispersion Coefficient of Induction Motor
The power factor and dispersion coefficient of an induction motor have relationship.The smaller the dispersion coefficient the better the power factor. Power factor is an … Read more
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 get added … Read more
Why the rotor winding of three phase wound rotor induction motor is star connected?
The stator can be either star or delta. Many motors have a winding scheme and coils with six connections that allow the windings to be … Read more
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 three phase supply fed to … Read more
