Description (Brief)
An electric motor with counter and magnetic brake. Page magneto motor, with counter attached. Horseshoe magnet, painted red, placed horizontally with a two-coil electromagnet set to rotate at the poles. The magnet is 10 1/2" long and 4 1/2" wide. A copper disk, 5 1/2" in diameter is mounted on the base, and apparently is to be driven by the motor. This may be some form of Arago's disc, adjustable on its base. No manufacturer's name is apparent on the specimen. The counter determines armature revolutions. Reference: Davis Manual of Magnetism (Boston, 1869) page 212 for magnet & armature construction. The counter mechanism appears modern.
