Electronic Design: Stepper Motor Controller Circuit Using TDA2030

Motor Circuit. - This is the other electronic design circuit for implementating of TDA2030 IC in this time for you. This electronic design circuit mentioned with stepper motor controller using TDA2030 IC as the major component used.

The electronic design circuit of stepper motor controller circuit look like shown in Figure 1 below. From the circuit shown, that there many other major component used like CD4017 IC, LF356 IC, diodes, resistors, and capacitor.

Beside we will show you electronic design circuit and component parts need, we also will give you global description about this circuit. So, please enjoy to continue reading this article until finish and get more useful.

Electronic Circuit Design

Component Parts

  • TDA2030 IC
  • CD4017 IC, 
  • LF356 IC, 
  • Diodes, 
  • Resistors, and 
  • Capacitor
Description

The electronic circuit design like in Figure 1 above show you stepper motor controller circuit using TDA2030 IC. Other component need also that can supply with low voltage DC 12V source to charge this IC and all system component. With this electronic design circuit you can produce stepper motor controller system that useful now.

According CircuitDiagram blog mentioned that the circuit which come from Elektor Electronics Magazine (Author: Gert Baars), can also supply motor currents up to 3.5 A, which means it can be used to drive relatively large motors. The circuit is also short-circuit proof and has built-in over temperature protection. Two signals are required for driving a stepper motor. In logical terms, they constitute a Grey code, which means they are two square-wave signals with the same frequency but a constant phase difference of 90 degrees.

IC1 generates a square-wave signal with a frequency that can be set using potentiometer P1. This frequency determines the rpm of the stepper motor. The Grey code is generated by a decimal counter in the form of a 4017. Outputs Q0 and Q9 of the counter go high in succession in response to the rising edges of the clock signal. The Grey code can be generated from the outputs by using two OR gates, which are formed here using two diodes and a resistor for each gate, to produce the I and Q signals.

Here “I” stands for “in-phase” and “Q” for “quadrature”, which means it has a 90-degree phase offset from the I signal. It is common practice to drive the windings of a stepper motor using a pair of push-pull circuits for each winding, which is called an “H bridge”. That makes it possible to reverse the direction of the current through each winding, which is necessary for proper operation of a bipolar motor (one whose windings do not have centre taps).

Electronic Design: Unipolar Stepper Motor Driver Circuit using CD4093 and CD4013 IC

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.

Beside we will show you electronic design circuit and component parts need, we also will give you global description about this circuit. So, please enjoy to continue reading this article until finish and get more useful.

Electronic Circuit Design

Component Parts

  • CD4093, 
  • CD4013, 
  • LM7805 IC
  • Resistor
  • Variable resistor
  • MOSFET IRFZ44
  • Capacitors
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.

Description

The electronic circuit design like in Figure 1 above show you digital fan speed control circuit using CD4510BE IC. Other component need also that can supply with low voltage DC 12V source to charge this IC and all system after down by IC LM7809. With this electronic design circuit you can produce stereo channel selector for your audio system that useful now.

According Circuitdiagram blog mentioned that the current step number is displayed on a 7-segment display. Speed can be varied over a wide range because the circuit can alter the voltage applied to the fan motor from 130V to 230V RMS in a maximum of seven steps.

The triac used in the final stage is fired at different angles to get different voltage outputs by applying short-duration current pulses at its gate. For this purpose a UJT relaxation oscillator is used that outputs sawtooth waveform. This waveform is coupled to the gate of the triac through an optocoupler (MOC3011) that has a triac driver output stage.

The pedestal voltage control is used for varying the firing angle of the triac. The power supply for the relaxation oscillator is derived from the rectified mains via 10 Kohm, 10W series dropping/limiting resistor R2.

The pedestal voltage is derived from the non-filtered DC through optocoupler 4N33. The conductivity of the Darlington pair transistors inside this optocoupler is varied for getting the pedestal voltage. For this, the positive supply to the LED inside the optocoupler is connected via different values of resistors using a multiplexer (CD4051).

The value of resistance selected by the multiplexer depends upon the control input from BCD up-/down-counter CD4510 (IC5), which, in turn, controls forward biasing of the transistor inside optocoupler 4N33. The same BCD outputs from IC5 are also connected to the BCD-to-7-segment decoder to display the step number on a 7-segment display.
