DRIVE DEVICE FOR DRIVING A COMPONENT OF A HOUSEHOLD APPLIANCE, HOUSEHOLD APPLIANCE AND METHOD FOR OPERATING A HOUSEHOLD APPLIANCE

摘要

The invention relates to a drive device (2) for driving a component (3) of a household appliance (1), comprising an electric drive motor (4) and a control device (10) for setting an electric power output delivered to the drive motor (4), wherein the control device (10) is designed to detect a measurement variable US, which is correlated with an amplitude of a mains voltage UN that can be supplied to the drive device (2), and to identify on the basis of said measurement variable US whether the amplitude of the mains voltage UN is below a predefined threshold value and, if this is the case, to limit the electric power output to a value greater than zero. Using such a procedure, a limit in terms of the current intensity of the motor current I1, l2, I3 and also in terms of an operating temperature of the drive motor are set. This is advantageous with respect to material savings during the production of the drive motor (4). At lower operating temperatures, less material via which the heat has to be evacuated is correspondingly required for the drive motor (4). As a result, savings can be achieved in terms of the production costs of the drive motor (4) and the valuable installation space in the household appliance (1).
