A motor having two inner field cups in which the stator coils are placed, and outer cups which fit over the inner cups. The coil lead wires pass out through U-shaped openings in the inner and outer field cups, and are protected by an elongated grommet having first and second wire protecting portions
A motor having two inner field cups in which the stator coils are placed, and outer cups which fit over the inner cups. The coil lead wires pass out through U-shaped openings in the inner and outer field cups, and are protected by an elongated grommet having first and second wire protecting portions which fit in respective openings. These portions are generally U-shaped when not constrained by external forces and are joined by an elongated center section. The grommet is manufactured of a flexible material to permit deformation of the legs of these portions upon pressing of the outer cups into place, to close around the wires.

A grommet unit for protecting at least two pairs of wires, for use with apparatus having two U-shaped wiring openings, each open outwardly in an opposite axial direction, and two apparatus covers each having a flat-bottomed U-shaped opening, in an installed condition said cover openings being open toward each other and aligned in the axial direction, said unit comprising: a center section having first and second ends defining an axial direction between said ends, and first and second wire protecting portions each extending from a respective end, each wire protecting portion comprising a bottom part and two legs, said legs being spaced from each other in a width direction transverse to said axial direction and each extending outwardly from said bottom portion to a respective tip; and, in a thickness direction transverse to said axial and width directions, each wire protecting portion having a given thickness, and said center section having a thickness less than said given thickness arranged such that each wire protecting portion projects in a same thickness direction with respect to the center section, at least said legs being made of a flexible material and, in an undeformed condition, the legs of a respective wire protecting portion converging toward each other from the bottom part to the respective tips, whereby upon placement of each of the wire protecting portions into a respective U-shaped wiring opening of said apparatus, a respective pair of wires for the apparatus can be passed between the leg tips of each wire protecting portion and placed adjacent the respective bottom part, and upon movement of respective covers into installed conditions opposite each other, the flat-bottomed cover openings will engage the respective leg tips and deform the legs of each wire protecting portion toward each other such that each leg is bent around a respective wire to provide protection against abrasion by the cover. An electric motor comprising: a central stator portion defining an axial direction, having first and second U-shaped openings aligned axially with the open ends of the openings pointing away from each other, two stator coils arranged within the stator portion, each having two wires passing radially outward through a respective one of said U-shaped openings, two covers, each having a flat-bottomed U-shaped opening, said flat-bottomed U-shaped openings being open toward each other and aligned with a respective stator portion opening, and a grommet unit comprising a center section having first and second ends defining an axial direction between said ends, and first and second wire protecting portions each extending from a respective end, each wire protecting portion comprising a bottom part and two legs, said legs being spaced from each other in a direction transverse to said axial direction and each extending outwardly from said bottom portion to a respective tip, at least said legs being made of a flexible material and, in an undeformed condition, the legs of a respective wire protecting portion converging toward each other from the bottom part to the respective tips; said wire protecting portions being seated in respective stator portion openings and said legs being deformed by engagement with respective flat bottoms of said cover openings such that each of said legs is bent around a respective wire and protects it from abrasion against the bottom of the cover opening.
