Abstract	A new technique of continuously generating reactive power from the stator of a brushless induction machine is conceived and tested on a 10 kW linear machine and on 35 H.P. and 150 H.P. rotary cage motors. An auxiliary magnetic wave, travelling at rotor speed is artificially created by the space-transient attributable to the asymmetrical stator winding. At least two distinct windings of different pole-pitch must be incorporated. This rotor wave drifts in and out of phase repeatedly with the stator MMF wave proper and the resulting modulation of the airgap flux is used to generate reactive VA apart from that required for magnetization or leakage flux. The VAR generation effect increases with machine size, and leading power factor operation of the entire machine is viable for large industrial motors and power system induction generators.
