摘要： A clothes washing machine system including a method of detecting a load unbalance. The washing machine system includes a cabinet having a drum rotatably mounted therein. A motor is coupled to the drum for rotating the drum within the cabinet. A memory device is accessible by a processor, such as a digital signal processor (DSP). The memory contains program code for implementing a method that includes determining the motor torque ripple, determining the motor speed, and determining the load unbalance mass based on the motor torque and speed.

摘要： The washing machine system (100) includes a cabinet (102) having a drum (104) rotatably mounted therein. A motor (106) is coupled to the drum for rotating the drum within the cabinet. A memory device (108) is accessible by a processor (109) , such as a digital signal processor (DSP) . The memory device contains program code for implementing a method of controlling a spinning washing machine drum comprising the steps of spinning the drum, monitoring a predetermined parameter of the spinning drum, and stopping the drum in response to the monitored parameter.
