Estimation of iron losses in a SynRM with segmented rotor

Besides the copper losses and mechanical losses, iron losses are inevitably reducing the efficiency of an ac machine. Despite being generally agreed to be much smaller in proportion in comparison to copper losses at lower speed, it is nonetheless necessary to be estimated before concluding that it c...
