content: A bi-polar direct current motor set on a wooden base with an armature mounted below the field poles. Pulley on one end of armature, commutator on the other. The aluminum angles serving as brush mounts, the brush holders and brushes themselves are not original to the piece but appear to have been added later so the unit could be operated, possibly as a museum demonstration. Two brass binding posts are set near the commutator. Inlaid circuit wires on bottom of base. No extant maker's markings.
