Edison Machine Works Dynamo, (3 folders, ca. 1890)Scope and Content
The schematic illustrates two dynamo designs, both showing armatures, field magnets, and external wiring connections. Each dynamo features a commutator, which converts alternating current (AC) generated in the coils into direct current (DC). The N (North) and S (South) poles of the magnets indicate the magnetic field's direction, crucial for the function of a dynamo. The switching mechanism shown in the middle controls the flow of current, ensuring proper operation and regulation. The connections to an external controller or switchboard allow the operator to monitor and manage the dynamo's output.Context
This blueprint originates from The Edison Machine Works, located in Schenectady, New York, which was a key manufacturing facility for electrical equipment in the late 19th and early 20th centuries. The diagram depicts magnet connections for standard dynamos, essential for generating direct current (DC) electricity in early power systems. In his work for Edison, Lewis Latimer may have traveled to this Schenectady plant, which became the point of origin for the General Electric complex that eventually was built there.Collection
