Driving Bipolar Stepper Motors -  Stepper motors are devices, which convert electrical impulses into discrete mechanical rotational movements.  in a typical stepper motor, power is applied to two coils.  Two stator cups formed around each of these coils,  __ Designed by Seiichi Inoue

Driving Stepper Motors -  Stepper motor are commonly used for moving robots.  if you love experimenting, stepper motors will give hours of great fun.  Learn how to generate the basic step sequences (full-step vs.  half-step) , and what a full bridge driver is.   __ Designed by Projects & Ideas from Nutchip.com

Dual Stepper Motor Driver for a Robot Differential Drive -  This article describes the hardware and the software used to control two stepper motors suitable for a robot differential drive.  The circuit accepts two 2-bit words that command each of the motors to go forward, backward, hold a position, or to idle.  it also provides an output signal when a step is being taken.  it is a flexible design allowing for unipolar and bipolar motors __ Designed by J. L.  John Girard

Dual Stepper Motor drivers using UDN2542 -  The UDN2540B is a quad darlington power driver, manufactured by Allegro.  Each output can sink up to 1.8A continuous.  The typical applications include print heads, relays, solenoids, and stepper motor control.  it is a replacement for L6221A.  in this Dual stepper motor drivers design we use two UDN2540B to drive two stepping motors at the same speed.  Each motor can be independently controlled.  The S1, S2 switches control the ON/OFF and the moving direction of Motor1.  The S3, S4 control the Motor2, respectively __ Contact info @ wzmicro.com

Full-featured Dual Hbridge -  Dueal non-shortin H-bridge with brake__ 

Full-featured Dual H-bridge -  I had always assumed that dynamic braking would be most effective at higher speeds.  However, actual tests using a Faulhaber (micro mo) gearmotor showed that the brake would hold a motor almost stationary.  These gearmotors are so well made that I can turn the 4 mm diameter shaft with light finger pressure.  For the tests I had mounted a 90 mm diameter wheel, which gave me tremendous mechanical advantage.  I found with the wheel mounted that I could barely turn the motor against the brake.   __ Designed by Bruce Robinson

High-Rate Electronic Speed Control with BEC & Brake -  This electronic speed control (ESC) for brushed motors combines the features of two of my earlier designs.  One was a high-rate 30A ESC with a brake, and the other a high-rate 12A ESC with a BEC (receiver battery eliminator circuit).   __ Designed by Stefan Vorketter

Implement a stepper-motor driver in a CPLD -  02/15/07  EDN Design Ideas:  Replace a hard-to-find stepper-motor-driver IC with a programmable-logic device Design by Stephan Roche, Santa Rosa, CA

Inexpensive logic controls stepper Motor -  EDN Design Ideas:  March 26, 1998    [  NOTE:    FILE
has multiple design, scroll for this one.]  A number of sophisticated ICs  for stepper-motor control are now available. However, the advanced features of these chips--self-clocking, high-current drive, and full-step, half-step, and direction control--are often unnecessary or remain unused. For a design that needs to control only the number of steps, drive speed, and direction, you can make a very simple and inexpensive driver using two low-level logic chips (Figure 1). Design by David Ellis, Ellis Lindauer, Pullman, WA

Make a Simple Circuit ramp generator for stepper Motors -  04/04/02 EDN Design Ideas:  Stepper motors are synchronous motors that step at the pulse rate of the driving signal.  For the motor to move quickly, the stepping rate must be fast.  However, because of motor and load inertia, the motor often cannot go from 0 rpm to the desired number of revolutions per minute in one step.  Therefore, most stepper motors receive their drive from a pulse chain that starts out slowly and Design by Richard Brien, GSI Lumonics, Wilmington, MA

MD-4 8031 Microcontroller Motor driver kit -  The MD4 is a stepper motor driver design utilizing the 80C31 microcontroller.  The design is very similar to the MD-2 stepper motor driver board except that this board has an on-board +5V regulator so it does not require a dual voltage power supply to run.  it uses two Allegro UDN2540B ICs  to driver the stepper motors.  The U1 is 8031AH microcontroller which can be replaced with any 80C32, 87C51, 87C52 or flash base microcontroller 89C51, 89C52 families.   __ Designed by www.wzmicro.com

Microstepping stepper Motor driver with PBM3960 & TEA3720 -  This Microstepping motor driver offers a short cut to get familiar with microstepping.  it is a complete system to driver the bipolar stepper motor in micro-stepping mode as well as the half step and full step modes.  This board is built around the Ericsson PBM3960 (NJR NJU39610) microstepping controller and TEA3718 stepper motor driver __ Contact info @ wzmicro.com

More stepping Motors -  There are so many ways to drive a stepper motor, Here is another circuit that use 74LS194 4 bit bi-directional universal shift register as a phase generator and UDN2543B to drive the unipolar stepper motor.  U1 74LS04 provide the necessary clock pulse for the circuit.  S1 is the direction selection switch and S2 turns ON/OFF the motor.   __ Designed by www.wzmicro.com

Nu-based stepper Motor drive -  A nifty (single-IC !) circuit to drive the bipolar stepper motor that's a part of floppy drives:  __ Designed by Wilf Rigter

NuStepper -  Uses just a single IC ('though not one you're likely to have in your "parts box") to give you reversible motor drive __ Designed by Wilf Rigter

One component drives stepper Motor -  The extremely simple circuit in Fig 1 drives a stepper motor directly from 12V ac , 60 Hz power supply.  Usually you need switched-dc voltages to drive a stepper motor.  But a stepper motor will run off ac lines if you introduce a 90 phase shift between the voltages applied to the motor's two windings.  in this case only one 6.8uF non polarity capacitor is needed.   __ Contact info @ wzmicro.com

One Wire Barometer - OWW is an application for Linux and RISC OS to drive the 1-wire weather station. . . . Designed by Simon Melhuish

Optically isolated stepper Motor controller -  These are some very high-level instructions for building the Opto-isolated Stepper Motor Controller. Not really a lot to say. Most of the construction is self-explanatory using the PCB artwork, the overlay, and the schematic. Note that the pad for pin 1 on ICs  and such are square to help in proper placement. All ICs  on the board are NOT oriented the same way, so pay attention. __  Contact:  wrb @ cbnews . att.com

PC-Based Stepper Motor Controller -  This stepper motor controller is perhaps the cheapest, smallest and simplest.  A pair of H-bridges with a software program written in C++ is used to control the bipolar stepper motor with...__ Electronics Projects for You

Plane Motor Controller with High-Rate ESC, BEC & Brake -  This electronic speed control (ESC) for brushed motors combines the features of two of my earlier designs.  One was a high-rate 30A ESC with a brake, and the other a high-rate 12A ESC with a BEC (receiver battery eliminator circuit).   __ Designed by Stefan Vorketter

PWM DC Motor control with SG3525 -  This PWM DC Motor driver circuit is ideal for the accurate control of DC motors as well as other applications like lighting levels and small heaters etc.  The circuit converts a DC voltage into series of pulses, such that the pulse duration is directly proportion to the value of the DC voltage.  The great advantage of such a circuit is that almost no power is lost in the control circuit __ Contact info @ wzmicro.com

RF Wireless PWM DC Motor Speed control -  The wireless PWM DC motor transmitter circuit consists of WZ-X01 RF module, Holtek HT-640 encoder and 8-bit A/D converter.  U1 ADC0804 converts the analog voltage to digital data; U2 encodes that data (D0~D6) along with D6, D7 and transmitting through the RF transmitter module.  The potentiometer VR1 varies the voltage to the A/D U1 pin6,  __ Contact info @ wzmicro.com

Rotary Controller Positions Stepping Motor -  EDN Design Ideas:  08/03/95    The circuit in Fig 1 uses a servo potentiometer, as opposed to a rotary switch or encoder, to provide the necessary drive pulses for a stepping motor.  This motor positions a pointer by the rotation of a manual control.  The circuit must be precise, allow a rapid response, and be simple to use. (This circuit was part of a complex apparatus used for a series of physiological tests.) Another requirement is that the control had to be a small, handheld, battery-operated device.    Design by TG Barnett and ME Rosenberg, Department of Physiology, Queen Mary and Westfield College, London, UK
