Most people understand how an electric motor takes electrical energy and transforms it into mechanical energy. However, they may not know where equipment like the Reliance DC motor B5010ATZ came from and how DC motors changed the world. Here is a brief history on electric DC powered motors.
The Power of Magnetism
If you take permanent magnets and place similar poles together, they repel each other. When you put opposite poles close, they attract and pull themselves together. But what if you control a magnet so it could have magnetic properties one minute and none the next? This is what happens with electromagnets.
Oersted
Back in the early part of the Nineteenth Century, a man named Oersted connected some wires to a source of electricity and discovered this created a magnetic field. In less than two decades, a number of discoveries and inventions appeared which eventually led to modern DC motors like the Reliance DC motor B5010ATZ. Many people contributed to the design and invention of the direct current motor.
Faraday
Faraday proved Oersted’s theory by using mercury (as a conductor) and a permanent magnet. He then placed a wire just above the mercury and connected each end to a battery. The wire formed a loop over the permanent magnet in the mercury. He also tried reversing the position of the wire and magnet. The electromagnetic energy created motion as the wire and magnet-attracted or repelled each other.
This was the first time; electric energy got turned into mechanical energy. Although it is a crude representation of a modern Reliance DC Motor B5010ATZ, it gives you an idea of the basic principles driving the DC motor. Thanks to DC motors, elevators move people and materials up and down long distances. Large manufacturing equipment like conveyors (needing precise speed control) get their power from direct current motors. These are just a few examples.
