... field orientated control. Vector control decouples three phase stator current into two phase d-q axis current, one producing flux and other producing torque. This allows direct control of flux and torque. So by using vector control, the PMSM is equivalent into a separately excited dc machine. The mo ...

3 Electric Currents from Magnetism
... Real transformers are not perfectly efficient. Because of resistance in the coils, they lose some of the energy put into them as heat. The power loss increases as the current increases. Power companies want to decrease loss to maximize the amount of energy they transmit. Therefore, they use high vol ...
