Running external IPM intelligent power module

[Bryce1263]

Has anyone used this library to run a hv bldc motor that runs through an external intelligent power module? i am trying to find a solution to run a fan and compressor from a mini split condenser.

Yes. We have successfully tried. Please check out these threads.

IGBT Driver NFAM5065L4BT SimpleFOC board

I am opening a new thread for that one, since the old one was for my TI driver. @Franz_Schmidt I was finally able to get a clean PWM low voltage signal out of the driver. I found a few small errors that prevented me originally from getting results, due to me cutting too many corners when designing the board. Eventually I was able to contact an on-semi engineer who pointed out the biggest problem, which was really easy to solve, I had to connect the over-current sense to ground via 100R to bri…

IGBT driver dev board

Hi all, I just finished assembly of my IGBT driver board with FNB43060T2 that I plan to use with some 80v BLDC motors I have. Obviously I’m looking to use FOC for the switching, hopefully around 16khz or 18Khz switching. It’s not tested yet, just come out of the reflow oven… I would add some photos but it gives me some weird error that it could not convert from png to jpeg… my photos are jpg anyway… Just see it assembled in the video: [IGBT FOC dev Board] I’ll make sure to be fil…

Is that what you had in mind?

Thanks! I posted to this forum with my current project.

I see. I was under the impression you want to run an integrated module, or design your own module, not an entire pre-fabricated board. It would be almost impossible to find help with that here on this board. At the very least you need the schematics for the pre-fabricated board.

Thanks for the help. This is only a two later board so it could be feasible for me to reverse engineer the schematics. At least for what’s driving these ipm modules.
