MiVESC - smaller version of VESC 6

Postby lakotamm » 17 Sep 2017, 07:47

Hello, guys! :-)

2 days ago I finally started working on the project which I had been considering for the last 2 months - a smaller version of VESC. Currently, I am in a phase of choosing the best components, therefore, if you have any good ideas, let me know :-) I want to finish the schematic this month (September) the latest.

Targetted specification:
Input voltage - 52V
Current - 15A passive cooling, 30A constant current
PCB size - 35x25mm

Did you consider to monitor the Fets Vds instead of using shunts as done here:
Maybe not linear enough for sensorless FOC though. But so much saved space..

Existing version here:

Look at NTMFS5C604NL, LM5101A and AD8417 thats what I will be using in my next iteration. But if you can fit direct fet it will be better.

70mm x 18mm

We're looking for a smaller CAN-controlled ESC for a copter.

Size and parameters of LittleBee 30A would be perfect.

How is your project progressing?
