ABSTRACT:
An electric motor drive system comprised of a main winding providing energizing current in a rectilinear wave form. The wave form has energization intervals. The electric motor drive system is also comprised of an auxiliary winding providing a first spiked pulse and a second spiked pulse which oppose each other, and each of which have an essentilaly instantaneous leading edge corresponding to a given energization interval. In a preferred embodiment, the leading edge of the first spiked pulse corresponds to the rise of the corresponding energization interval, and the leading edge of the second spiked pulse corresponds to the fall of the energization interval.
