Arduino Based DC Motor Speed Control
... The voltage supplied to a DC motor controls its speed. Arduino cannot supply variable DC output. Arduino lacks a true analog output. Use Pulse-width modulation (PWM) to simulate a variable DC supply voltage. PWM is a common technique for supplying variable power levels to “slow” electrical ...

Basics of AC Motors
... Since work is the product of force times the distance applied, work can be expressed in any compound unit of force times distance. For example, in physics, work is commonly expressed in joules. 1 joule is equal to 1 newton-meter, a force of 1 newton for a distance of 1 meter. In the English system ...

Stepper motor
A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed.Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
