This paper shows that winding drives in combination with a continuous variable transmission (CVT) will lead to reduced rated power as well as an increased efficiency of the electrical drive. First practical experiments with imitation of a winding operation were performed to verify the theoretical investigations.
Servo drives comprise a significant potential of energy saving which has not been considered sufficiently up to now. Simple changes in the motion control of energy optimal and jerk limited motions can be implemented which lead to a reduced acceleration rms-value and slightly increased maximal acceleration. The resulting reduction factors for dimensions and moved masses lead even to further savings...
