What are the different types of induction motors?
DOL(Direct Online starting) Star Delta starting Auto transformer starting Above methods are for squirrel cage induction motor Rotor resistance starting is used for wound rotor or slip ring induction motor
Does induction motor has rotor winding?
Yes, the induction motor has a rotor winding. It is usually one turn, shorted. This is how the magnetic fields generated in the stator induce a current in the rotor, which subsequently generates a torque from the opposing magnetic fields, stator to rotor.
What happens if 3 phase supply is given to stator and rotor both in a induction motor?
its impossible to give suppy to rotor of an induction motor,because of it a closed path for circulating currents.
What is squirrel cage induction generator?
Squirrel cage type is a type of Induction motor. It tells that the rotor is "squirrel cage" type. Another type of induction motor is with "slip ring" type of rotor. Squirrel cage type is most widely used Induction motor.
How does an induction motor develop torque?
The shaft of an AC induction motor rotates because of the torque created by the interaction between the magnetic field of the stator and the magnetic field of the rotor.
What are the different types of induction motors?
DOL(Direct Online starting) Star Delta starting Auto transformer starting Above methods are for squirrel cage induction motor Rotor resistance starting is used for wound rotor or slip ring induction motor
What is the use of double cage rotor in induction motor?
to obtain high starting torque
What is the useful of open end winding of induction motor?
Standard induction motor has a closed squirrel cage rotor, where as open ended induction motor has split phase rotor.
How induction motor is made self starting?
just put a auxilari winding on the rotor (in the salient pole)..
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
Is a three phase induction motor self starting?
A three-phase motor has a steady rotating magnetic field generated by the stator coil, and the rotor just follows the field.
How do you increase starting torque in cage type 3-phase induction motor's?
by adding external resistance to the shaft of rotor
What are the reasons for connecting resistance in the rotor circuit when starting wound rotor induction motors?
To limit the starting current in slip ring induction motors.
How do you convert from slip ring motor to induction motor?
short the rotor terminals.
Does induction motor has rotor winding?
Yes, the induction motor has a rotor winding. It is usually one turn, shorted. This is how the magnetic fields generated in the stator induce a current in the rotor, which subsequently generates a torque from the opposing magnetic fields, stator to rotor.
What did mean by standstill in induction motor?
rotor speed = 0
What happens if 3 phase supply is given to stator and rotor both in a induction motor?
its impossible to give suppy to rotor of an induction motor,because of it a closed path for circulating currents.
