Abstract: A method of manufacturing a rotor for an electric motor that includes producing a generally flat metal strip, bending one section of the strip relative to another section, and rolling the strip to form a cup-shaped shell.

Abstract: A stator for an electric motor includes a stator core including a yoke and a plurality of arms extending radially from the yoke. The stator includes an end piece secured to a radial end of each arm of the stator core. The stator core has a length defined along a longitudinal axis of the stator, and each end piece has a length defined along the longitudinal axis of the stator. The length of each end piece is greater than the length of the stator core.

Abstract: According to one illustrative embodiment, a washing machine comprises a motor including a plurality of coils and one or more permanent magnets, an inverter configured to supply current to the plurality of coils and to measure a back electromotive force (BEMF) waveform from the plurality of coils, and an electronic control unit (ECU) configured to (i) integrate the BEMF waveform to generate an integrated BEMF waveform, (ii) determine a magnetic flux of the one or more permanent magnets using an amplitude of the integrated BEMF waveform, and (iii) control the current supplied by the inverter based at least in part upon the determined magnetic flux.

Abstract: An apparatus and method for detecting an imbalance in the laundry load and effecting a redistribution of the imbalance by reducing the rotational speed of the treating chamber such that part of the load may redistribute while part of the load remains satellized, without ceasing rotation, and increasing the rotational speed back to a spin speed after redistribution.

Abstract: A method for determining the amount of laundry in a laundry treating appliance comprises a drum defining a treating chamber for receiving the laundry and a motor for rotating the drum that may be operated to simulate a spring to oscillate the drum relative to a predetermined rotational position. The angular decay of the drum relative to the predetermined position may be determined and used to determine the amount of laundry.
