Peripheral speed constant control
In winding systems such as wire drawing machines and spinning machines, the outer diameter of the
wind-up roll increases due to the amount of material being wound onto the roll and the actual wind-up
speed increases when winding is continued at a constant shaft speed. To maintain the wind-up speed
at the outer periphery at a constant speed, a speed sensor is used to detect the wind-up speed, and
the speed of the motor shaft is controlled so that the wind-up speed is kept constant.
