The Asynchronous Condenser: A Brushless, Adjustable Power Factor Induction Machine

A new mechanism of continuously generating reactive kVA from the stator of abrsh ess induction machine is formulated and tested on 10 kW and 35 H. P. laboratory machines. A space-transient magnetic wave, travelling at rotor speed must be artificially created and at least two distinct windings of different pole-pitch must be incorporated. The per -unit kvar generation effect increases with machine rating, and leading power factor operation of the entire machine is viable for large industrial motors and power system induction generators.
