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

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).

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

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

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

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.
