Abstract
An inverter-fed three-phase electrical motor ( ) for a household appliance is grounded through a protective conductor ( ), with the motor being particularly provided for the direct drive of washing machines. The motor includes a pick-up for high-frequency currents originating from an actuation of the inverter ( ) and conducts the currents to one pole of a D.C. voltage supply ( ) for the inverter ( ) through an ohmic or capacitive shunt path ( - ), with the shunt path leading from a stator ( ) of the motor which is installed electrically insulated into the household appliance and is not connected to the protective conductor ( ).
