H02K 3/38
H02K 15/14

US Classification:

310 71, 29596

Abstract:

A stator comprises a cavity formed into the insulator of the windings. The non-wound wire sections that extend from the windings and the electrical conductors attached thereto are housed within the cavity. A cap locks onto the stator insulator and prevents the non-wound sections of wire from migrating out of the cavity.

International Classification:

D06F 23/00
H02K 9/193

US Classification:

68140, 310 54

Abstract:

An integrated motor and control system has an electric motor. A control controls operation of the motor. A housing substantially covers at least two sides of the control. The housing has an opening and a liquid guide for guiding liquid toward a predetermined position in the opening to prevent liquid from contacting the control. The control is mounted on at least one of the electric motor and the housing. A heat sink can be extended through the opening in the housing to cool the control. The liquid guide can facilitate natural convection over the portion of the heat sink exterior of the housing. The integrated motor and control system can suitably be used in a washing machine or other appliance where liquid may be encountered.

Abstract:

An apparatus includes an inner rotor motor and a stationary wiring conduit. The inner rotor motor includes a stator and a rotor spaced at least in part radially inside the stator. The rotor is rotatable relative to the stator about an axis. The rotor includes a rotatable shaft that presents a shaft bore extending axially therethrough. The stationary wiring conduit extends through the shaft bore and is fixed relative to the motor housing. The shaft bore rotatably receives the wiring conduit, such that the wiring conduit is permitted to remain stationary as the shaft rotates.

International Classification:

H02K 1/27
H02K 21/16

Abstract:

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.

Abstract:

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.

Abstract:

A blower motor assembly includes a blower wheel and a motor. The blower wheel includes an integrally formed hub. The motor includes a shaft rotatable about an axis. The hub presents a radially inner hub surface that at least in part defines a hub opening. The inner hub surface defines an inner cross-sectional dimension. The shaft is axially received within the hub opening, such that the blower wheel is supported by the shaft for rotational movement. The shaft includes a toothed region defining a plurality of arcuately spaced apart teeth. Each of the teeth includes a cutting edge. The teeth present an outer cross-sectional dimension that is great than the inner cross-sectional dimension of the inner hub surface, such that the cutting edges of the teeth cut a plurality of grooves in the inner hub surface as the shaft is axially received in the hub opening.
