FOC can make a different

Vehicles for agriculture use have to work at low speeds with high loads. Usual motors don’t have the torque needet, even at using reducers or getting very expensive quickly.

My intention to solve this was to use a Direct Drive system with FOC driven Stepper Motors instead BLDCs.

It took me some time, but the result shows that it was worth the effort.

Interesting!
Did you use SimpleFOC with the MKS Servo42?
Or did you write your own code?

Hi Antun,

The MKS Servo42 are FOC drivers which, if I interpret the description correctly, are based on SimpleFOC. They are controlled very simply via Step/Dir — I wouldn’t have been able to manage anything more complex than that.

Here a link to the board at github, - i use the Servo42C Board.
