Direct-drive model railroad motor

DETAILED DESCRIPTION In accordance with the present invention there is provided a motor comprising an axle adapted to rotate about an axis; a wound armature fixed to and concentric with the axis; two segmented wheel commutators fixed on opposite ends of the axle concentric with the axis, a motor casing surrounding and enclosing the armature; and a pair of permanent magnets attached opposite one another on the sides of the casing.
Each commutator comprises a plurality of segments insulated from one another.
The commutators are adapted to conduct electricity across a set of tracks.
The casing further comprises opposite end caps and a cylindrical body concentric with the axis.
The motor may further comprise a bearing aperture in each casing end cap and a first and second bearing, each bearing fixed to and adapted to rotate with the axle concentric with the axis.
Each bearing is mounted in a bearing aperture in the casing end cap and has a plurality of wire channels therethrough.
Such motor also comprises a plurality of wires, each wire electrically connected between one segment of one wheel commutator and an opposite segment of the opposite wheel commutator.
Between said commutators, each wire is disposed through one of said bearing wire channels in said first bearing, across said armature, and through one of said bearing wire channels in said second bearing.
Each wheel may consist essentially of conductive segments separated by nonconductive epoxy, and a non-conductive bushing centered therein and adapted to receive the axle.
