Spectral Micro - BLDC motor controller / overview

[@BuffRobotiX]

Awesome product and nice music! It's great to have one of these boards available for under a hundred bucks.

[@source-robotics]

Glad you like it!

Looks great. Just started learning about FOC and this areives in my feed🎉...

It's always great to see these sorts of open source projects. The background "music" was too irritating for me to finish watching the video. It would be great if you released the same video without the background noise.

[@source-robotics]

Thank you for feedback, we will release presentation style video with text soon. In this clip the music is maybe too loud compared to the voice

How does this differ from SimpleFOC?

[@source-robotics]

@@pyalot In this video it runs our custom firmware that is higher performance than simple foc is not a framework like simplefoc but full driver firmware that has communication support, error handling, mutiple modes... But this driver also supports simple FOC out of the box and we have examples in the GitHub folder

[@pyalot]

@ I would suggest putting a comparison on the projects site, cause that is what everyone looking for FOC solutions will wanna know.

Why are BLDC motor controllers always so expensive?

[@alexandrepv]

Does it work with standard Nema17 stepper motors? If so, what is the maximum RPM?

[@source-robotics]

@@alexandrepvThis is for BLDC motors so it does not work with steppers. But we have developed a FOC stepper driver that is similar to this one that we will release soon. I suggest you join our discord since we post updates there and some early demos.

[@source-robotics]

@@alexandrepv On the RPM side for those stepper driver we developed, they can reach much higher RPM than open loop alternatives. We pushed a standard stepper to 3000 RPM with FOC stepper drivers while in open loop its limit is around 1200-1500

@@source-robotics I just did, thank you very much :) Is it the "stepfoc-stepper-servo"? I can't see any messages in there. Do I need to join something to be able to see them or there hasn't been any messages yet?

[@source-robotics]

@alexandrepv yup thats it, there are no posts at this moment but we will start posting soon.

[@alexandrepv]

@@source-robotics Great :) thanks again for the answers and I look forward to hearing more!
