Stepper Motor Data

program shows the basic operation of the stepper motors

This program shows the basic operation of the unipolar and
bipolar stepper motors. In addition there are demos of a translator
, oscillator and indexer.http://www.wimb.net/index.php?s=delphi&page=6

Basic theory of Stepping Motors
Stepping motors are electromagnetic, rotary, incremental devices
which convert digital pulses into mechanical rotation. The amount
of rotation is directly proportional to the number of pulses and the
speed of rotation is relative to the frequency of those pulses.

Static or holding torque - displacement characteristic
The characteristic of static (holding) torque - displacement is best
explained using an electro-magnet and a single pole rotor . In
the example the electro-magnet represents the motor stator and is
energized with it's north pole facing the rotorhttp://www.sapiensman.com/step_motor/

Stepper Motors: Principles of Operation


Permanent Magnet stepper motors incorporate a permanent magnet
rotor, coil windings and magnetically conductive stators. Energizing
a coil winding creates an electromagnetic field with a north and south
pole .
