Scope and ContentThe 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.
