notes: label: Description (Brief)
content: No extant maker's markings. Two pairs of electromagnets, with the movable one provided with a two-part commutator. Cores are U-shaped. The fixed one is mounted on a brown wooden base, and the movable one is above it, mounted in a frame consisting of two brass pillars joined by an arm of iron. Specimen was initially catalogued as a generator, but inspection reveals no method for cranking the armature coils, therefore this item must be an elementary from of DC motor. The use of electromagnets in armature and field suggests a date later than 1832. Reference: Groenendijk Catalog, page 20, item 5h-14.
