The evolution of transmissions

Published: February 27, 2023. The very first automobiles needed a way to transmit power to the wheels. Early methods of accomplishing this were comprised of exposed belts and pulleys, effectively creating a single-speed transmission.

OverviewHistorySystemBulk transmissionAdvantage of high-voltage transmissionModelingHigh-voltage direct currentCapacity

Commercial electric power was initially transmitted at the same voltage used by lighting and mechanical loads. This restricted the distance between generating plant and loads. In 1882, DC voltage could not easily be increased for long-distance transmission. Different classes of loads (for example, lighting, fixed motors, and traction/railway systems) required different voltages, and so used …
