Stepper motors are so named because each pulse of electricity turns the motor one step. Stepper motors are controlled by a driver, which sends the pulses into the motor causing it to turn. The number of pulses the motor turns is equal to the number of pulses fed into the driver. The motor will spin at a rate that is equal to the frequency of those same pulses.

Most often used to control fans in air conditioning and heating systems, the AC Controller allows for more control of the airflow. The AC Controller also aids in adjusting the speed of pumps and blowers. More recent appliions include conveyors, cranes and hoists, machine tools, extruders, film lines, and textilefiber spinning machines.

Notes: This circuit is known as a latching circuit, because it "latches" in the "on" state after a momentary action. The contact in parallel with the "Run" switch is often referred to as a sealin contact, because it "seals" the momentary condition of the Run switch closure after that switch is deactuated.. The followup question of how we may make the motor stop running is a ...
