Electric Motors
Diehl's work at Singer to improve the sewing machine led to developments in electric motors, first to power sewing machines and later for other uses as well. In 1884 at the Franklin Institute in Philadelphia, Pennsylvania he demonstrated a dynamo, modeled after his smaller motor, which generated a current for arc lamps, sewing machine motors and incandescent lamps, all covered by his patents. The judicial committee at the exhibition judged it to be one of the best dynamos exhibited.

Famous quotes containing the words electric and/or motors:
“Persons grouped around a fire or candle for warmth or light are less able to pursue independent thoughts, or even tasks, than people supplied with electric light. In the same way, the social and educational patterns latent in automation are those of self- employment and artistic autonomy.”
—Marshall McLuhan (1911–1980)
“When General Motors has to go to the bathroom ten times a day, the whole country’s ready to let go. You heard of that market crash in ‘29? I predicted that.... I was nursing a director of General Motors. Kidney ailment, they said; nerves, I said. Then I asked myself, “What’s General Motors got to be nervous about?” “Overproduction,” I says. “Collapse.””
—John Michael Hayes (b. 1919)
