Full Documentation in pdf format

In free-standing mode an internal square-wave oscillator based on IC2:B of the 4093 supplies timing pulses to the OSC output. The frequency of these pulses and thus the speed of the stepper motor is controlled by the trimpot VR1 (100K.) A series 1K resistor controls the maximum frequency. You may increase the value of this resistor for your own needs. These pulses are fed into the STEP input which is buffered and inverted by IC2:D. This helps prevent false triggering. Similarly, IC2:C buffers and inverts the DIRection input. A SPDT taking the input to +5VDC or ground controls the direction of rotation.

This kit is a very useful circuit for driving 5, 6 or 8-wire unipolar stepper motors. It can operate either freestanding or PC-controlled. The circuit and stepper motor may use separate supply voltages. Four high current IRFZ44 MOSFETs are used at the output. The motor can either be stepped by the internal, variable oscillator or by external 5Vp-p pulses. The direction of rotation can be set with a switch. This innovative circuit only uses standard CMOS ICs 4013, 4030 and 4093. Full explanations are given. Specifications: Supply Voltage: (kit) 7 - 12Vdc (stepper motor): 8 - 35Vdc Supply Current: (kit) 0.1A max. (stepper motor): 6A max. per winding Dimensions: 46 x 75mm, 25mm height

STEPPER MOTOR CARD

PLEASE NOTE: CLOSEOUT ITEM. LIMITED QUANTITY AVAILABLE.

For bi- and unipolar motors (maximum 1A). Easy to connect with K8000RS. High precision possible (up to 0.9°, or even more when using a motor with reduction). While the motor turns you can simultaneously check the status of switches using K8000RS, or drive another motor. You can always give an emergency stop signal. Test program included. Manual test buttons to test the card without K8000RS interface. Can be used in every application where positioning is needed (for example a plotter, a printer, a valve, …). 1 x High precision motor (MOTS1) included (12V).

I²C controlled via K8000RS
communication address of the card (from 0 to 15) selectable via DIP-switches on the PCB (remark : max. 4 x K8005 cards on one K8000 cards)
adjustable drive speed
programmable in TurboPascal for DOS, Quick Basic and Visual Basic (Win95/98/ME)
emergency stop can be sent to one or all cards
power supply: 7 to 25V DC or AC / 1.5A (maximum current depends of the motor type)

Bipolar Chopper Stepper Motor Driver Kit

This bipolar chopper drive allows you to get better performance from your stepper motor.
It uses a dual full bridge motor driver based on SGS Thompson chips L297 & L298. Motor current for each phase is set using an on-board potentiometer and the controller is capable of
handling motor winding currents of up to 2 Amps per phase.
It operates from a DC supply voltage of 9-36V. The drive provides all basic motor controls, including full or half stepping of bipolar steppers and direction control. Works with our range of large bipolar stepper motors MO-101, MO-102 and MO-103
All signals (Step, Direction, Enable) can be interfaced to external logic or a microcontroller. You can easily control the motor from your computer's parallel port or our serial stepper controller card!
This controller is perfect for desktop CNC applications.
