Electric motors and the new, modern energy-efficient motors are a far cry from the items one would have found back in the early years of the nineteenth century, emerging from the experimental workshop of Michael Faraday in 1821. The experimental setup he invented proved that the application of an electrical current through a magnet created a field which induced linear movement. However, it was not until ten years later that the practical application of an electric motor capable of turning machinery was invented and demonstrated by the British scientist William Sturgeon. .
The motors were expensive to manufacture and also expensive to repair, because of the components. It was not until about 1855 that practical, affordable, and reliable electric motors first appeared on the scene. The forerunner of all modern energy efficient motors and electrical motors in general was invented around 1873 by Znobe Gramme. The “Gramme Machine” was the first electric motor that was an efficient power source for diverse types of machinery. The story goes that the motor was invented purely by accident. Sometimes, the great breakthroughs in science and engineering through the ages has been a combination of luck and accidental discovery.
Practical electric motor design and manufacturing has revolutionized society as a whole, especially with the introduction of fractional horsepower motors (FHP), which are electric motor units with a power-rated output of 746 watts or less. The consumer-led boom, immediately following World War 2, led to the rise in these types of electrical motors which are the mainstay of washing machines, refrigerators, vacuum cleaners, and other domestic and commercial applications and appliances.
Modern vehicles would be incomplete without FHP units: adjustable seats, windscreen wipers, central locking systems, electric-operated sun roofs and convertible roofs. In fact, some thirty-five percent of all FHP motors is used in the manufacture and assembly of cars, trucks, buses and other vehicle types. Without modern efficient electric motor design and manufacture, the industrial and residential landscape we are used to would be completely different than it is now.
