Hi guys,
I would like to know if there's someone out there who can enlighten me on some issue regarding induction motor. The induction motor is acting like a generator as a dc motor drives it. This is obtain by varying the Nr > Ns. However, Nr can only be increase to a certain limit for eg, once the current hit the rated current. To increase the range of Nr, we can add some resistance to the rotor terminals. by a 3 phase variable resistor. so in theory wise, where do i add these resistance to? Wrt the exact equivalent circuit of the induction motor? If this generator (induction motor) is connected to a grid, there is bound to be losses. Can someone tell me what are the losses apart from stator loss, core loss & copper loss?
