Along with the electric power electronic installation's widespread use, in electrical network's overtone pollution condition is day by day serious. At present widely uses the overtone processing method is reduces the overtone or the filtration overtone as far as possible. The traditional filter equipment not only facility cost high invests in a big way, moreover wasted in vain has been possible to perform the use the overtone energy.
The present paper proposed that one kind carries on the electrical machinery dragging using the overtone the method and the equipment, this equipment can the electrical network harmful, and present is filtered by the electric power department the overtone energy uses, uses in actuating the direct current machine.

With the power of the widespread use of electronic devices, power grids in the harmonic pollution is becoming increasingly serious. Now widely used harmonic approach is to minimize harmonic or harmonic filters. Filtering equipment not only the traditional high-cost equipment investment, but also a waste can be used by the harmonic energy. This paper presents a harmonic use of a motor drag the methods and devices, the device can be harmful to the power grid and the electricity sector is being filtered out of the harmonic energy use, used to drive DC motor. Key words: Harmonic Harmonic Harmonic suppression against the passive filter fundamental harmonic drag degaussing circuit
