PROBLEM TO BE SOLVED: To solve the problem of a textile machine having a plurality of spindles being started/stopped individually that noise due to belt driving is significant when the drivers of respective spindles are operated synchronously using a timing belt and efficiency lowers due to energy loss, and that when an arrangement for operating respective drivers synchronously by controlling each of a plurality of inverters connected with one converter is employed, the arrangement is complicated because each drive motor is controlled by an inverter at all times and a software control performing synchronous operation control of respective spindles is required. SOLUTION: Drive source of each spindle comprises a synchronous induction motor 53, 54,... connected in parallel with at least one inverter power supply 21. |
