Method of controlling the speed of rotation of the drum of a centrifugal spinning machine has as a function of the unbalance and machine for the óoeuvre this.

摘要

The machine being provided with a motor (2) to alternating current in order to cause said drum (1) and a control device (3, 4, 5) of the speed of the motor (2) by adjusting the angle of the passage of current (i) passing through it, it is determined, as a quantity representative of the unbalance, the amplitude variations (,) of said angle of the passage of current on at least one turn of the drum (1).
