I don't have a proper power supply for the motor yet, so question number one is what kind of PSU would be sufficient? . If I've understood correctly, these motors may draw tens of amps under load.
It's not stated what kind of PSU is used on the project. And it's probably not directly comparable to the motor I would use. The original project uses DC-motor with Rated Current ≤6.0A and Unload Current 20A.
Also - is there a ready H-bridge / motor shield for this kind of use - I would use ESP8266 or Arduino Nano to control the motor at start.
