Abstract

A speed governing device for washing machines for overcoming the defect of generating radiofrequency noises without using any filter. In addition, the device exploits the advantages of DC motors in general without suffering from the inconveniences thereof. The arrangement essentially comprises a DC motor fed through a constant current transformer and a rectifier having rectifying elements whose opening is controlled by a device which delivers opening pulses synchronized with the zeros of the AC feeding current until the speed of the motor is below a predetermined value, while the delivery of pulses is discontinued as the predetermined value aforementioned is exceeded.
