    摘要: 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.

    摘要: A fan assembly includes a fan housing and a fan. A switched reluctance fan motor is mounted in an inlet of the fan housing and includes a shaft that is connected to the fan. The switched reluctance fan motor includes a stator with a plurality of circumferentially-spaced stator segment assemblies that include a stator segment core. Winding wire is wound around the stator segment core. A rotor tends to rotate relative to the stator to a rotational position that maximizes the inductance of an energized winding. A drive circuit energizes the winding wire around the stator segment assemblies based on the 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.

    摘要: Methods and apparatus are disclosed for assembling an electric machine. The electric machine includes a plurality of stator segment assemblies that are mounted inside of a housing of an electric machine. The stator segment assemblies are positioned around an outer surface of an assembly fixture. The stator segment assemblies are held to the assembly fixture using a magnetic field that is generated by the assembly fixture. The housing is press fit or hot dropped over the stator segment assemblies. If the housing is hot dropped, the housing is heated to cause the housing to expand. The housing is positioned over the stator segment assemblies while the housing is hot. The housing cools and contracts around the stator segment assemblies to form an interference fit with the stator segment assemblies and then the stator and the housing are removed from the assembly fixture.
