SimpleFOC DriveShield - A big (more powerful) brother of the SimpleFOCSheild

It seems like CB1, CB2, CB3 capacitors from EasyEDA project are rated to 16V, shouldn’t they be rated above the max allowed input voltage?

Yes absolutely!
Make sure to use all of them at above 30V which is the max for the mosfets.

Thank you Antun for developing this!

I would love to test this out for my project. Can you recommend a hardware configuration (motor + encoder + MCU) that is known to work at high power and high RPM with this driver? Which motor and encoder did you do your testing on?

TIA :slight_smile:

I’d definitely go for an STM chip a G4 or an F4 at least, this way you can use the low-side current sensing class (even though it has the inline hardware) and get a very high frequency current loop.

The motor and the sensor will depend on your application. I’ve got very good results with encoders, but spi sensors are also fast and very popular. :slight_smile:

If you want to do only the velocity control, you might also try sensorless from our drivers library. It’s still a bit under tester but at quite a few people had some good results with it already :slight_smile:

I develop a custom tadpole trike and I am looking for a suitable board.

I read on the oshwlab page that you linked, that the project is only meant for internal resistance of 10 ohms and above.

You didnt meantion anything about the in the initial post itself, so I just want to be sure?

You are aboslutely right. It’s a typo, a copy+paste error :smiley:
The baord is designed for high-power motors, no 10 Ohm resistance limit.
I’ve removed the line from the readme. :slight_smile:

That is wonderful news

So I am capable to use it with brushless motors, who then power electric vehicles.

Is there something, that prevents the availability of the board in the shop?

And which motors would you recommend to use with it?

Thank you for the SimpleFOC DriveShield! :+1::clap::slightly_smiling_face:

Is it possible to replace MOSFETs

in order to increase max ratings for voltage and current of the SimpleFOC DriveShield?
