Measurement and Modeling of Iron Losses in Electrical

But even if electrical machines and iron losses have been studied for more than 100 years, there is still a discrepancy between simulated and measured iron losses in electrical machines. So called loss correction factors, machine factors or build factors are used to match the simulations to the corresponding measurement results.

Basic principles of electrical machines electric equipment

Dec 31, 2015Basic principles of electrical machines. In an electrical machine, the currents in all the windings combine to produce the resultant flux. The field system produces flux. Voltages are induced in the windings such as those of an armature. When the armature carries current, the interaction between the flux and the current produces torque.
