Abstract: A bracket can connect a luminaire to a junction box or other housing or structure, for example at a ceiling. The bracket can be mounted to the junction box using one or more fasteners. The bracket can comprise two tabs, and the luminaire can comprise two corresponding slots. Alternatively, the bracket can comprise two slots, and the luminaire two corresponding tabs. The luminaire can be attached to the bracket by positioning the luminaire so that the two tabs are inserted into the two slots and rotating the luminaire so the slots and tabs engage and lock.

Abstract: A stator for a dynamoelectric machine improves the cooling of the stator winding without increasing the size of the stator winding or the entire stator. The stator is of a unique construction wherein the size, and more specifically the cross sectional area or volume of the individual conductors is greatly reduced, while the total number of conductors is increased. In addition, a multiple filar construction is employed to avoid the potential for high levels of inductance and resistance in the conductors and to minimize the interference between the cascaded stator end loops and the housing that surrounds the stator.

Abstract: An electrical machine comprising a rotor (26) mounted on a shaft (29) for rotation therewith and defining an axis of rotation, and a stator (54) disposed coaxially with and in opposition to the rotor (26). The electrical machine further comprises a housing (22, 24) enclosing the stator (54) and the rotor (26), the housing (22, 24) having a first axial end with a wall with an inner surface and an outer surface and a second axial end with a wall with an inner surface and an outer surface. The electrical machine also includes a first cooling tube (80′) having a first end and a second end and an embedded portion thereof embedded between the first inner surface and the first outer surface of end wall (81). A second cooling tube (82′) has a first end and a second end and an embedded portion thereof embedded between said inner surface and said outer surface of the wall (83) of the second axial end.
