Abstract (en)
[origin: EP0539617A1] In order, in the case of a variable-speed electric motor (M) monitored by a speed-measuring device (tacho-generator TG) in a control device (RV) and fed from an alternating current source (R; Mp), in particular a series motor, for an automatic washing machine, to be able to guarantee effective unbalance monitoring with a low outlay on construction and manufacture, the invention provides to connect in series with the tacho-generator (TG) an unbalance sensor, provided for the purpose of unbalance monitoring, in the form of a microswitch (MS) which opens when an impermissible unbalance is reached and thus interrupts the connection to the control device (RV). <IMAGE>
