Electric Motors Everywhere.

- Abstract
This article focuses on the uses for electric motors. Electric motors are used in home, work, and recreation, silently doing work for us in converting electrical energy into mechanical energy! We see them in appliances such as vacuum cleaners, refrigerators, microwave ovens, computers, automobiles, and even toothbrushes. A VCR has several miniature DC motors, as do DVD and CD-ROM players. Other common uses are elevators, pumps, power tools, and manufacturing equipment. Electric motors have played a key role in exploration efforts deep into the sea and in space ventures. Do you remember the Mars Sojourner Rover? Or the current space exploration robots named Spirit and Opportunity? These space robots use miniature electric motors and servomechanisms as a means of propulsion and motion. These miniature motors are compact and powerful and require little energy to operate them. Surprisingly, there were 39 miniature motors on each of the Spirit and Opportunity rovers! There are many activities found in technology education classes that use miniature electric motors.
