Motors
Electric motors are the backbone of modern automation. Motors convert electrical energy into mechanical energy, and the resulting motion and torque drives a load.
Motors come in all shapes and sizes and are found in a diverse range of applications like industrial fans, blowers, pumps, machine tools, household appliances, power tools, disk drives, conveyors, heavy machinery, robotics, and, more recently, motor vehicles.
For industrial applications, three primary motor types are most common: AC motors, DC motors, and servo motors. AC motors are driven by alternating current, and use electromagnetic induction to apply torque to the rotor. These motors can be single-phase, three-phase, and include several additional variations that serve different purposes. DC motors are powered by direct current, and use applied current and power to vary speed and torque. Servo motors are primarily used with position- or speed-control feedback systems needed for valves, machine tools, and other process systems.

Motors: Learn About Motors Here > Simply put, an electric motor converts electrical energy into mechanical energy. This is achieved by the principle of electromagnetic
induction. Electromagnetic induction is the principle that a current carrying conductor, when placed in a magnetic field will have a force
exerted on the conductor proportional to the current flowing and the strength of the magnetic field. The basic principles of electromagnetic
induction were discovered in the early 1800's by Oersted, Gauss and Faraday. However, it was Tesla who was able to take motor technology to the
next level in the late 1800's and revamped the manufacture of motors as well. Tesla was able to successfully garner 900 patents in the
electrical field that had relevance for motor applications.
