摘要
PURPOSE: A control device is provided to achieve improved efficiency of motors, reduce power consumption, and lengthen the useful life of a bearing by suppressing heating of the motor. CONSTITUTION: A control device(1) of motors(M1,M2,M3,M4,M5) for driving devices of a textile machinery, comprises inverters(DR1,DR2,DR3,DR4,DR5) for inverting AC power into a variable frequency and variable voltage; a judging unit(2a) for judging operating state of the devices of the textile machinery; and a controller(21) for changing output voltage-output frequency pattern of inverters on the basis of the result of judgement of the judging unit. The devices of the textile machinery include godet rollers(111,112) and a friction roller(127).
