I am building an autonomous dual motor drive machine for my design project at Uni. I have two 24VDC motors with operating current of 2A and stall current at 10 A each. The 24V and 10A requirement is quite limiting in the choice of motor drivers. I had initially planned on using 2 Pololu High-Power Motor Driver 24v12 but I am tight on budget and so probably can’t get approval to use them for my project.
I also looked at Dual VNH2SP30 Motor Driver Carrier MD03A (which is available at the electronics shop at my university for free) but it says that PWM operation is impractical above 16 V and I want to run my motors at the rated voltage of 24 V for the most part.
I am looking for any advice to solve the issue or to choose another cheaper product. (I need to keep the cost within $25)
Also, I thought of putting together a PCB motor driver on my own. Is there a circuit diagram for something like the Pololu High-Power Motor Driver 24v12 that I could refer to? (I am not an EE student, so I don’t know a lot about electronics)
