<p>There is provided a highly-efficient alternating current (AC) motor which improves efficiency and power factor to minimize power consumption. The highly-efficient AC motor includes a stator, a rotator having a secondary circuit for inducing current using the rotating magnetic field and generating torque, and an induction windig, which is inserted into the stator, insulated from the operation winding, and interlinked with the operation winding and the secondary circuit to induce electromotive force. The highly-efficient AC motor further includes a capacitor, which is connected to an output node of the induction winding to constitute a circuit for charging and discharging current due to induced electromotive force. The induction winding absorbs internal loss of the AC motor and performs a generative operation during the operation of the AC motor to minimize loss and greatly improve power factor. The electromotive force of the induction winding can be used for output of the AC motor or used to supply any additional load with power. Thus, power consumption caused by the AC motor is minimized to save energy considerably. Also, a rise in the temperature of the AC motor is inhibited, thus prolonging the life of the AC motor.</p> |
