I'm writing a persuasive essay for school and I need to know how the electric motor by Michael Faraday changed the world during the Industrial Revolution, yet still has a great impact on today's world. I know that without it transportation wouldn't be the same, but what are some other reasons it was/is so useful? (convenience, safety, etc.) Thanks!! :)
You are using the term electric motor too loosely because there is the DC type and AC. Also Faraday's motor was a proof of concept, and was not a practical design to use. The modern DC motor with a commutator got its design ideas from Thomas Davenport's motor. The modern AC induction motor is the design of Tesla. The electric motors of both AC and DC changed the world by replacing the combustion engine in manufacturing applications with proven reliability and ease of speed and torque control (DC motors initially, since speed and torque control of AC motors was hard to figure out back then). Electric motors (mostly AC induction) are used in applications such as plastic injection molding machines, milling and lathe machines, compressors, forge presses, pumps, cranes, locomotives, conveyor belts, oil well pump jacks, hammer mills, ball mills, sawmills, printing presses, HVAC systems, etc. Basically, your average Joe would not know that electric motors greatly outnumber combustion engines and that electric motors are what make the majority of the products we buy. I hope you write a good essay so you can educate people that the combustion engine is the underdog, not the electric motor which has more market share. :)
When the electric motor Faraday invented is turned into a turbine; run by wind, water, steam, etc. it becomes a generator and produces alternating current. Thus his electrical motor design has a two-fold purpose. Many products have motors running on the same principle today - vacuum cleaners, power saws and so on - even heating and air conditioning units which force air through buildings and homes.
