A power controller for an appliance, especially a washing machine, is operative to place the appliance into a hyperspin mode. When in the hyperspin mode, the washing machine rotates its washing basket at a higher speed in relation to a traditional spin mode for the washing machine. In order to prevent damage to the washing machine that could result from spinning heavier, unbalanced loads at higher speeds (i.e. hyperspin speeds), a controller detects vibration of the washing machine basket while the items are being spun at a lower speed (i.e. at the speed of the traditional spin mode). If the washing basket vibration is less than a predetermined threshold vibration value, the washing machine controller operates to cause the washing machine to rotate its washing basket at a higher speed. This results in removal of more water from the clothes being spun dried.

A washing machine comprising a laundry receptacle, a variable speed induction motor driving the laundry receptacle at a wash speed and as spin speed, a drive for powering the motor, and a wye-delta switch for connecting the drive and the motor in a wye configuration during the wash cycle or a delta configuration during a spin cycle. A controller controls the speed of the motor and the switch.
A washer includes an outer cabinet, a washtub disposed in the cabinet, a rotating tub rotating by a driving motor and being disposed in the washtub, a top cover disposed on top of the cabinet, the top cover being provided with an opening for loading and unloading clothes, a control box-receiving portion formed on a portion of the top cover, a control box having a circuit board for controlling the washer, the control box removably received in the control box-receiving portion, and a protecting cover for covering the portion of the top cover where the control box is received.
