An electric machine includes a stator carrying two sets of multiphase windings. The sets are electrically isolated from each other and have an angular space displacement of A° electric corresponding to a torque ripple of harmonic order N. Responsive to current flow through the sets with a phase shift of A° electric, N±1 harmonic orders of resulting stator magnetic fields cancel to preclude formation of the torque ripple of harmonic order N.
