Motor Circuit. - This is the other electronic design circuit for controlling motor stepper driver universally in this time for you. With this circuit you can control unipolar stepper motors with 5, 6 or 8 wires. It uses four MOSFET IRFZ44. This circuit can be operated in free-standing or PC-controlled mode.
The electronic design circuit of unipolar stepper motor driver circuit look like shown in Figure 1 below. From the circuit shown, that there many integrated circuit (IC) used look like CD4093, CD4013, and LM7805 IC.

Description
The electronic circuit design like in Figure 1 above show you unipolar stepper motor driver circuit using CD4093 and CD4013 IC. Other component need also that can supply with low voltage DC 5V source to charge this IC and all system after down by IC LM7805. With this electronic design circuit you can produce motor stepper driver that useful now.
According Circuitdiagram blog mentioned that 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.
IC3:C and D (4030 or 4070 exclusive OR gates) invert the outputs available at Q and /Q outputs of each of the flip-flops (FF) IC4:A and IC4:B. The incoming step-pulses clock the FF, thus toggling the Q & /Q outputs and this turns the MOSFET’s on and off in sequence. The IRFZ44’s have a low on-resistance and can deliver up to 6A each without needing a heatsink.
Power to the stepper motor is connected to V+ and GND terminals as shown on the overlay. There is a separate power supply, KITV, to the 78L05 to power the IC’s. 9V – 12VDC will be sufficient. R2/C2 form a low-pass filter to filter fast-rise switching transients from the motor.
