In cumulative cascade connection of two induction motors, why does the net speed reduce? Also, how are the torques of the two motors in the same direction?
They are mechanically coupled, so both run at the same speed . One motor is driven by 50 Hz mains supply and its rotor emf is given to the stator of the other motor. How does this assembly work? How are the connections made to provide torques in the same direction and in the opposite direction? There are mathematical formulae about this in my book but I want to know what's happening in there physically.anorlunda said:Explain more about your cascade.
Are the cascaded electrically or mechanically on the same shaft?
Are two motors connected to provide torque in the same direction, or opposing connections?
How much mechanical load is applied relative to the ratings of the motor?
Edit: a drawing would be very helpful.
