Abstract
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.
