  • METHOD OF MANUFACTURING A ROTOR FOR AN ELECTRIC MOTOR FOR A WASHING MACHINE
    Publication number: 20150089794
    Abstract: A method of manufacturing a rotor of an electric motor is disclosed. The method includes securing a plurality of permanent magnets to a sheet to form a magnet chain, bending the sheet to engage an inner surface of each permanent magnet with a curved outer surface of an insert mold, wrapping a metallic strip around an outer surface of the sheet to form a yoke of the rotor, and molding a polymeric material over the magnet chain and the yoke to form a cylindrical shell.

  • METHOD OF MANUFACTURING A ROTOR FOR AN ELECTRIC MOTOR FOR A WASHING MACHINE
    Publication number: 20140000097
    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.

  • STATOR FOR AN ELECTRIC MOTOR INCLUDING SEPARATELY FORMED END PIECES AND ASSOCIATED METHOD
    Publication number: 20130249328
    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.

  • DETERMINATION OF MAGNETIC FLUX AND TEMPERATURE OF PERMANENT MAGNETS IN WASHING MACHINE MOTOR
    Publication number: 20130119905
    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.
