Method for controlling a hyperspin mode in an appliance

Abstract

A power controller for an appliance, especially a washing machine, is operative to place the appliance into a hyperspin mode. The power controller implements a method of operating a washing machine that comprises operating a washing machine motor at a first speed to rotate a laundry receptacle coupled to the washing machine motor at the first speed, collecting rotation velocity data regarding the laundry receptacle during rotation of the laundry receptacle, comparing the rotation velocity data to a parameter threshold, and operating the washing machine motor at a second speed in response to the comparison between the rotation velocity data and the parameter threshold indicating that the laundry receptacle is balanced. If the rotation velocity data does not indicate that the laundry receptacle is balanced, the motor remains at the first speed.
