METODO DI COMANDO DI AZIONAMENTO PER TAMBURI DI ROCCATRICE AUTOMATICA

摘要

In an automatic winder wherein each of a plurality of winding units thereof has a traverse drum driving motor and an inverter for driving the motor, the numbers of those inverters which are to be decelerated and accelerated are controlled in such a manner that the regenerative energy generated upon deceleration of the motors and the motor driving energy may be cancel each other.
