Abstract :
It is known that if an electrical machine does not operate at nominal load, nominal magnetic flux is not required. This means that if magnetic flux is reduced, iron losses can be reduced also. On the contrary, copper losses at the stator are increased for a given constant load. Using the proposed method, power supply of the stator and of the rotor can be controlled in order to achieve optimal magnetic flux, under which value total power losses can be minimized
