As a theoretical problem in the conventional analyses on linear induction machinery (LIM), the existence of the stationary pulsating m.m.f. in the single layered LIM is pointed out and examined by the field mappings of the magetic flux and the secondary eddy current. According to the field mappings, it is found that there exists different electromagnetic phenomena in the single layered LIMs compared to the completely double layered LIM: the S.P. MMF in the single layered LIM always exists and produces the alternating flux through all over the length of the motor to affect the fields considerably. From the comparison between the two single layered LIMs with different kind of resistivities, it is proved that the flux due to the S.P.MMF under constant current operation increases with the secondary resistance because of the required higher supply voltage and the suppression of the induced secondary eddy current.
