== Commonly Used Motors in Mechanisms==

* '''[http://www.explainthatstuff.com/induction-motors.html AC Induction motors]:''' These motors work by the principle of changing the power to different pairs of magnets placed diametrically opposite to each other, as the power changes, according to the Lenz’s law there is opposition to the change in the loop which is suspended between the pairs of these diametrically opposite magnets. Thus they respond by rotating as well. So as we keep changing the pair that is powered, the loop continues to rotate to catch up with it. This is how this motor works.

* '''[https://en.wikipedia.org/wiki/Brushed_DC_electric_motor Brushed DC motors]:''' These motors have a part called a commutator that reverses the current when the loop completes one half cycle. Thus when the current reverses it acts in a similar way as powering different pair of magnets in an AC Induction motor and thus the cycle continues.

* '''[https://en.wikipedia.org/wiki/Stepper_motor Stepper Motor]:''' It works by the principle of rotating current in the coils placed diametrically opposite on the outside and then using these to align the pair of magnets on the rotor of the motor.

* '''AC Induction motor:''' High RPM and high torque requirements.

* '''Brushed DC motor:''' Limited life applications, low RPM and high torque requirements.
