The chain circuit of connection of coils of the stator winding is considered. The phase shift of a current in the coils is created with the help of capacitors between the coils and common bus of a winding. By presenting a winding as a chain of T-figurative two-port networks, we found an equivalent impedance of winding coils and the parameters of these two-port networks in the ideal idling mode by the calculation of a field in an active zone of an air motor gap with account of the final length of the magnetic core. The pulse field effects on the redistribution of inductive resistances and attenuation of coils. After replacement of each two-port network by the equivalent piece of a line with the distributed parameters, for this non-uniform line of the transfer simulating ideally a distributed stator winding, we found the current distribution along the length without the account of attenuation under condition of a constancy of wave resistance and absence of reflections from the line ends. We defined the distribution of a magnetic induction in the motor gap. We showed that it is possible to improve structure of the gap field by the changing of the distribution of the line current load. To receive the stator characteristics close to ideal, we must completely to eliminate a pulsing flux of a gap. In this case, there is a complete compensation of the consumption of magnetizing power.
