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).
