摘要:
A method includes heating a housing of an electric machine to thermally expand the housing, positioning a mount having power and control electronics assembled thereon and in contact therewith in the housing and against an internal stop defined within the housing, and allowing the housing to cool and thermally contract against the mount thereby forming an interference fit between the housing and the mount. The interference fit secures the mount within the housing. The mount and the housing have coefficients of thermal expansion such that the interference fit is maintained across an operating temperature range of the machine. The electric machine may also include a segmented or non-segmented stator within the housing.

An electric machine includes a housing, an end shield, a stator, and a rotor assembly. The end shield can define at least one pin, and the stator can define at least one track. The stator can be positioned on the end shield such that the pin is received within the track. The stator can be captured between the end shield and a stop within the housing. The rotor assembly can include an adaptor sleeve and/or a bearing with a plurality of steel rolling elements. End caps can be coupled to the stator, and power and control electronics can be integrated within the housing.

A rotor assembly for an electric machine includes a rotatable shaft, a rotor core coupled to the shaft for common rotation, and an impeller coupled to the shaft for common rotation. A bearing is coupled to the shaft generally between the rotor core and the impeller. The bearing can include an outer race sized smaller than an opening defined by the machine housing. The bearing can include steel rolling elements such as steel balls or generally cylindrical steel rollers. An adaptor sleeve can be disposed generally around the outer race. The adaptor sleeve can be disposed within the opening defined by the housing for securing the adaptor sleeve and the bearing within the opening defined by the housing.

A switched reluctance machine includes a stator with a plurality of circumferentially-spaced stator segment assemblies that include salient stator poles and inter-polar stator slots. Each of the stator segment assemblies includes a stack of stator plates forming a stator segment core, an end cap assembly, and winding wire wound around the stator segment core and the end cap assembly. The rotor defines a plurality of rotor poles. The rotor tends to rotate relative to the stator to maximize the inductance of an energized winding. A drive circuit energizes the winding wire around the stator segment assemblies based on a rotational position of the rotor. Each stator plate includes a first radially outer rim section and a tooth section that extends radially inwardly from a first center portion of the first radially outer rim section.

A washing machine includes a tub that is rotated by a switched reluctance motor. The tub includes an outer tub and an inner tub. The drive is a direct drive or a drive assembly that includes a shaft, a belt and a spinner pulley connected to the tub. The switched reluctance motor includes a stator with a plurality of circumferentially-spaced stator segment assemblies. Winding wire is wound around a stator segment core of the stator segment assemblies. A rotor is connected to the shaft that drives the belt and rotates the spinner pulley. A drive circuit energizes the winding wire around the stator segment assemblies based on a rotational position of the rotor. End cap assemblies are connected to opposite axial ends of the stator segment core. The end cap assemblies define an annular channel for receiving the winding wire and for preventing winding creep.

A winding end cap assembly for an electric machine with a stator and stator poles includes first and second end caps that are connected to opposite axial end surfaces of one of the stator poles. First and second inner winding retainer sections extend axially to connect an inner end of the first end cap to an inner end of the second end cap. The first and second end caps include an outer section, an inner section and a hub section that connects the outer section to the inner section. The first and second end caps and the first and second inner winding retainer sections define a continuous annular channel that receives and retains winding wire. First and second outer retainer sections connect the first and second end caps adjacent to the outer sections or the hub sections of the first and second end caps.
