Stepper Motor Basics

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.
