Method for improving the power factor of motor product

It is based on welding machine to present a method for improving power factor of the electrical products and influence, especially to raise the power factor with coil products. The main principle is shown as following: the primary and secondary windings of electrical product respectively around the same core of the two different cores column, the reactance coil windings wind the core columns of once and secondary windings, the effective turns of reactance coil windings are identical, the flux magnitude produced by two different reactance windings is equal but the direction is opposite, which produced the electromotive force sum is equal to zero, the reactance of reactance windings overcome the reactance of the power product windings and increase the output current of secondary windings, thereby the power factor of the electrical products is improved. At the same time the structural design principle using the reactance of reactance windings to overcome reactance of electrical windings and the wiring work principle are presented. Using above method can improve power factor of the electrical products, enhance capacity and reduce the emissions, wastewater, sludge and other emissions, which has a wide range of social benefits and application prospects. This effective method to increase power factor of electric welding machines has been nationally patented, with the patent number of 200510132604,2.
