inference on the topic :electric motor
Answers
Answer:
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.

Above: The first Davenport motor
1.) History and Inventors:
1834 - Thomas Davenport of Vermont developed the first real electric motor ('real' meaning powerful enough to do a task) 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.
The electric motor's world impact before light bulbs:
Trolleys and the connected power systems were very expensive to build but transported millions of people to work in the 1880s. Until the growth of the power grid in the 1890s most people (middle and low classes) even in cities did not have the electric light in the home.
It wasn't until 1873 that the electric motor finally achieved commericial success. Since the 1830s thousands of pioneering engineers have improved motors and created many variations. See other pages for more detail on the electric motor's vast history.
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 backwards 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.
