motor because there is no provision for supply to the
rotor.mean to say it next too impossible to connect a
supply to rotor.

i have one source transformer with the capacity of 50KVA, connected with two loads 10kw and second one is 15kw.. how can i calculate first load in KVA and second one in KVA .. because Kva rating, power factor rating of of transformer is different from the load… there must be some way to calculate load KVA rating and power factor….
