Beschreibung
Zusammenfassung:	The embodiment of the utility model discloses a filter and a motor driving system, the filter is applied to an inverter of a long lead driving motor, the filter comprises a differential mode inductance module, an RC absorption module and a common mode inductance module, an AC output port of the inverter is connected to an input end of the differential mode inductance module; the differential mode inductor module is electrically connected to the RC absorption module and the common mode inductor module; the RC absorption module is electrically connected to the common mode inductor module; the output end of the common mode inductor module is connected to the long wire. The filter is installed between the inverter and the long wire. Through the above mode, the embodiment of the utility model can filter the differential-mode harmonic wave of the AC output signal of the inverter, reduce the common-mode inductance load, and solve the problems of overlarge harmonic wave and line damage in the remote control of the sy
