How do you calcuate resistance for slipring motor?
it is related to Slip ring rotor max.currents and voltage ...
Why rotor contactor in external resistance of slipring motor connected in delta?
rotor contactor are used to cut the resistance in slip-ring motor connected through resistance box. resistance is proportional to torque. so by controlling rotor contactor resistance can be controlled and hence torque can be controlled. for more information check torque and speed characteristic of wound motor.
What will happen to speed-torque characteristics of an induction motor is the rotor resistance is increased?
If Rotor resistance is increased torque is increased
How do you increase starting torque in cage type 3-phase induction motor's?
by adding external resistance to the shaft of rotor
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.
How do you slipring motor is convert to inducton motor?
With a synchronous motor shorting the slip-rings together should make it work as an induction motor although perhaps not to an optimal degree.

Why using on motor star delta starter?
because at the starting the induction motor drawn a heavy current thats why we use starter to increase the starting resistance of the induction motor!
What will happen to speed-torque characteristics of an induction motor is the rotor resistance is increased?
If Rotor resistance is increased torque is increased
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 works on Electromagnetic induction?
Yes the Induction motor works on Electromagnetic induction principle.
How do you increase starting torque in cage type 3-phase induction motor's?
by adding external resistance to the shaft of rotor
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.
Applications of induction motor?
A single phase induction motor is mainly used in fans.It is capacitor start capacitor run induction motor.In three phase induction motor squirrel cage induction motor is mainly used in elevators,lifts,cranes.slip ring induction motor is mainly used in electrically driven ships.
What is a decripition of Nikola Tesla induction electric motor?
