Abstract：By analyzing the connection form of the motor stator winding,the relationship between input voltage and electromagnetic power,torque,as well as the components and cables of the motor load distribution system,this article concludes that AC 660 V power supply is applicable to all metro motor equipment. Through comparative analysis,this article also explains the advantages of substantial savings of nonferrous metals,reduction of initial investment and reduction of cable losses to metro motor equipment if AC 660V power supply is adopted.
