If stator & rotor of a 3-phase induction motor have different no. of poles, will the motor run or not??
We have .ht motor which is 60Hz.we run on 50Hz.so that it's speed reduce but we had one prob.that motor winding temp increase up to 135 deg.we want reduce this temp.what to do?we arrange ext.cooling fan but not much effect.we want reduce this temp. Inhouse without affecting much.cost. also don't want reWINDING OF MOTOR?
why do we prefer a 3-phase delta connected load rather than star connected?

what do you mean by PF correction. A motor is rated at 15 kw,415 volts, 0.7 pf and eff of 0.92. The powerfactor is improved to 0.98 by adding capacitors at the bus. calculate the current drawn by motor under full load condition before and after pf correction
