STEPPER MOTORInterface using 8051DEFINITIONStepper motors are electromechanical device, which convert electrical pulses into proportionate discrete mechanical rotational movement.STEP AND STEP ANGLEA step is defined as the angular rotation produced by the shaft each time when the motor receives a step pulse.The rotation of the shaft due to each step is called step angle.

SPEED CONTROLAverage motor speed is proportional to the rate at which the pulse command is delivered.Therefore can be used for speed control.APPLICATIONSRobot armsPaper-drive mechanism in printersMachine-tools controlProcess-control systemElectric watchesTapesDisk drive systems, etc.
