How do you calcuate resistance for slipring motor?
it is related to Slip ring rotor max.currents and voltage ...
What should the value of the resistance box for a 5 hp slipring induction motor?
its depends upon rotor voltage and current
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 are the functions of slip ring carbon brush external resistor in an alternalting EMF generator?
good question the use of slipring carbon brush is to give excitement to the generator , as the carbon brosh contact the rotor slip the rotaion and the speed of the generator increases we can say as an external force by anonrafee blueroz_27@yahoo.com
Which type of motor is used in wet grinders?
A universal motor is used to operate a food mixer.

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.
What should the value of the resistance box for a 5 hp slipring induction motor?
its depends upon rotor voltage and current

Whether vfd is suitable for slip ring motors?
400hp slipring motor has been short circuited and connected to the 315kw variable frequency drive. The vfd has run continuously for 2 days without any problem.After a supply break the vfd couldnot resume but indicating a message of impedence short.
What happen when slip ring induction motor overloaded?
Let me give you a different yet convincing answer, as you over load the machine, it will run slow to get more induced emf in rotor, we all agree to a point that,as it slows down it will have more emf but as the electrical angle increases beyond 90, for slipring machine with no automatically induced poles unlike cage rotor, this deter the flux bonding between stator and rotor , As already loaded , this is a cumulative action there by machine stalls, Do let me know if you need further explanation.
