Electric Motors
History
Electric motors have many parts that were created over time and put together. The battery was created by Alessandro Volta in 1800, The magnetic field and electric current was created by Hans Christian Oersted in 1820, and the electromagnet created by William Sturgeon in 1825 all laid the foundation for the electric motor. The first real electric motor was created in 1834 by Thomas Davenport. The early motors created spinning discs or levers that rocked back and forth. These early motors had no use for humankind, but paved the way for future motors.
Necessary Parts Of An Electric Motor
-AC or DC Power
- Base Coil to create a magnetic field
-Armature
-Commutator
-Copper Wire
-wire brushes
The armature is one of the most difficult parts of the motor to build. It is a long rod that has the commutator and an electromagnet that reacts with the magnet from the base coil. With the alternating positive and negative charges that run through the wire brushes and into the commutator it allows the armature to spin while reacting with the base coil magnet.
