The electric motor was first developed in the 1830s, 30 years after the first battery. Interestingly the motor was developed before the first dynamo or generator.
History Of Motor:
1834 – Thomas Davenport of Vermont developed the first real electric motor although Joseph Henry and Michael Faraday created early motion devices using electromagnetic fields. The early “motors” created spinning disks or levers that rocked back and forth. These devices could not do any work for humankind but were important for leading the way to better motors in the future. Davenport’s various motors were able to run a model trolley on a circular track and other tasks. The trolley later turned out to be the first important application of electric power (it was not the light bulb). Rudimentary full-sized electric trolleys were finally built 30 years after Davenport’s death in the 1850s.
Motor leads to the generator:
After weak electric motors were developed by Faraday and Henry, another early pioneer named Hippolyte Pixii figured out that by running the motor backward he could create pulses of electricity. By the 1860s powerful generators were being developed. The electrical industry could not begin until generators were developed because batteries were not an economical way to power society’s needs.
How Motors Work?
Electric motors can be powered by alternating (AC) current or direct current (DC). DC motors were developed first and have certain advantages and disadvantages. Each type of motor works differently but they all use the power of the electromagnetic field. We will talk about the very basic principals of electromagnetic fields in motors before you can move on to the different types of motors.
AC electric motors use a secondary and primary winding (magnet), the primary is attached to AC grid power (or directly to a generator) and is energized. The secondary receives energy from the primary without directly touching it. This is done using the complex phenomena known as induction.
