An improved induction motor having at least one capacitive element electrically connected in parallel with and tapped to each phase of a delta- or wye-wound stator winding such that the capacitive elements are alternately charged or discharged during operation, thereby storing energy from and releasing energy to the windings. This alternate energy storage and release assists in controlling the level of magnetic core saturation and increasing motor efficiency under all operating conditions due to reduced hysteresis and eddy current losses. Motor starting or inrush current is also substantially reduced using this arrangement. In one embodiment, variable capacitors and switch elements are used to provide the ability to dynamically "tune" the motor winding for optimal efficiency.
