摘要： A drying device has been developed having a single electric motor configured to drive a drum and directly drive an air blower. The single electric motor is a non-line frequency electric motor. The drum is coupled to a support frame to enable rotation of the drum relative the support frame. The drum has an interior space for holding a load of articles, such as clothing. The motor includes a controller configured to regulate the angular velocity of the output shaft of the motor with reference to the current drawn by the motor.

摘要： An electric motor is provided. The electric motor comprises a stator and a rotor rotatable about an axis and spaced at least in part radially outside the stator. The rotor includes a plurality of arcuately spaced apart pole segments, a plurality of arcuately spaced apart magnets alternately arranged with the pole segments such that each of the pole segments is positioned between an adjacent pair of the magnets, a rotor can at least in part supporting the pole segments and the magnets, and a plurality of pegs. Each of the pole segments defines an opening therethrough and includes a generally arcuately extending wall structure positioned radially outside of and at least in part defining the opening. Each of the pegs extends through a corresponding one of the openings to secure a corresponding one of the pole segments relative to the can.

摘要： An electric motor includes a stator having a stator surface and a rotor rotatable relative to the stator. The rotor includes a plurality of poles, each of which is defined by a pair of magnets positioned in a V-shaped arrangement having a vertex positioned radially inward. The magnets present a mechanical pole angle of the corresponding pole. The rotor also includes a rotor surface that is opposite the stator surface. The rotor surface includes a plurality of circumferentially-spaced pole segments, each of which spans a respective mechanical pole angle. The rotor also includes a plurality of longitudinally extending recesses, each of which is positioned between adjacent pole segments.

摘要： An electric motor includes a stator and a rotor rotatable relative to the stator. The rotor includes a plurality of poles, each of which is defined by a pair of magnets positioned relative to each other in a V-shaped arrangement having a vertex positioned radially inward. Each of the poles includes a mechanical pole angle defined by the pair of magnets. The mechanical pole angle is about one-half of three hundred and sixty divided by the number of the poles of the rotor.

摘要： Various embodiments of an electric motor and electronic control for an electric motor are disclosed. An exemplary electric motor comprises a single-phase brushless permanent magnet electric motor. In exemplary embodiments, the electronic motor control is configured to commutate an electric motor at a frequency other than line frequency, perform pulse width modulation, and drive the electric motor with a drive waveform that approximates the counter-electromotive force of the motor.

摘要： A stator for use in an electric motor is disclosed. The stator comprises an annular core, a plurality of wedges, and a plurality of wedge-retaining structures. The core includes a plurality of arcuately spaced apart teeth. Each of the teeth includes a generally radial leg and a head projecting from the leg to present a pair of arcuately spaced apart head ends. A slot opening is defined between the opposed head ends of each adjacent pair of teeth. Each of the wedges is received within a corresponding slot opening. Each wedge-retaining structure is at least in part fixed relative to the core and cooperates with a respective one of the wedges to compressibly retain the respective wedge between the head ends.
