Where Did Electric Motors Come From?
When you look at a General Electric DC motor 506AY
, you see a history of electromagnetic-based power dating back to the early part of the 19th Century. Electric motors evolved from very simple apparatuses to the efficient modes of power driving the wheels of modern industry in the 21st Century. Here is a quick look at the history of these motors.
The Discovery of Magnet Induced Motion
If you place two opposite pole magnets close enough, they come to together on their own. When you try to touch two like pole magnets, they create a force which repels them apart. This is the basic power behind electric motors whether they run on alternating current or direct current like the General Electric DC motor 506AY.
Magnets and Rotation
After Oersted discovered current carrying wires produced a magnetic field, the world was never the same. In fact, many people around this time (1820-1870) began similar work, and some of them knew nothing (or very little) of the other’s work.
Barlow built the very first device to rotate on electromagnetic principles. This was only 2 years after Oersted made his discovery and it was called Barlow’s Wheel. A few years later (1834) Jacobi introduced the first electric powered motor. By 1838, Jacobi improved his motor, and it propelled a boat with fourteen passengers across a river.
Direct current motors came from dynamometers (generators). They work with magnetic power from a stator affecting a rotor, and the power gets reserved (commutator) to maintain the rotation process. By reversing the process of generating DC power, you can create a DC motor.
