Abstract

The circulation pump motor in a domestic dishwasher comprises a single-phase asynchronous motor (M) with a control device for controlling the run-up phase to overcome the initial drag. The control device uses a resistance (17) with a negative temp. coefficient coupled in series with the auxiliary motor winding (13), or with the main motor winding, or coupled in supply line to the motor (M). Pref. the main winding (11) and the auxiliary winding (13) are both coupled on one side to the a.c. supply via a motor cutout switch (14). The other terminal of the main winding (11) is coupled via a triac (15) to the opposite supply terminal. The auxiliary winding (13) is coupled in series with a run-up capacitor (12) and the negative temp. coefficient resistor (17), in parallel across the main winding (11), with a further triac (16) connected to the junction between the capacitor (12) and the negative temp. coefficient resistor (17) and to the opposite supply terminal.
