Abstract

A method and electric circuit for suppressing radio interference comprises an electric circuit for connecting and starting-up an electric asynchronous motor M1 used on automatic washing machines or on other appliances. The inductance of the motor windings L1 and L2 is used as part of the noise filtering circuit. The contacts c2 for controlling the motor are connected between separate parts of the stator windings L1 and L2. The terminals of the motor A1 and B1 are connected through a noise filter F1 to an electric supply. The inductance of the windings L1 and L2 contributes to the inductance of the filter F1 and thus increases the efficiency of the filter in suppressing radio-frequency interference upon start-up of the motor.
