This illustrates the BasicPI Firmware Stack in progress. What I always do in embedded applications is to make a “standard” main.cpp as follows: void AppInit() { // wire hardware } int main() { AppInit(); // start OS } A team I worked in years ago agreed on this standard so we should…
It’s been a while since I designed this 3KW 3-Phase Motor Controller without doing anything with it so I decided to give it an upgrade. The size of this is 100x25mm. It is very smal for it’s capacity and Perfect for larger drones. Removed 3rd current sensor. Remove the output holes at right and take…
This pic is of a 6368-190KV while I just received a 6368-280KV – a 3KW Outrunner BLDC w/Hall Sensors that costed me 60.- USD all in all. This will be my 3-phase test motor on the 3KW Motor controllers thought while my controller is max 60V @ 50A these motors have a spec 36V @…
I want to attempt a few changes on this 3-phase controller. Remove the 3rd current sensor marked in red at top. Remove the output holes at right and take the output directly from between the MOSFET’s. Add at least 1 temperature sensor. I can use more space between MOSFET channels and maybe squeeze in the…
This is a specialized 3-phase driver that uses DRV8301. It is more narrow than the 4 channel design and not so complicated to build. I did this design before I did the larger 4 channel design so it is several things on this design I improved on the 4 channel design. Temperature sensors are still…
