(b) The voltage caused by each phase winding resistance;
(c) The voltage caused by the changes of each phase
winding current;
(d) The voltage caused by the changes of other 3-phase
windings currents.
If the voltages caused by the each phase winding resistance
and by the change of phase current are moved behind
cycloconverter and considered as an external impedance, this
12-phase synchronous motor can be equivalent to a
fundamental back EMF.
