System for feeding electric power to motors for use in textile machine

摘要

There is provided a system for feeding an electric power to motors for use in a textile machine, which serves to feed the electric power to both of a plurality of spindle motors for driving individually a plurality of spindles and a draft motor for driving a draft roller, the system comprising: a converter portion for rectifying an A.C. current that has been obtained from an A.C. power source into a D.C. current; and a chopper portion for adjusting the output voltage of the D.C. current that has been obtained by the conversion in the converter portion, the electric power which has been outputted from the converter portion being fed to the draft motor through a draft inverter, the electric power which has been outputted from the chopper portion being fed to the plurality of spindle motors through a draft driver.
