I have an idea which would allow sharing current between multiple drives and will test it some day. It basically requires wiring all control signals/power lines parallel and power outputs wired parallel through power inductors. Same might work on Argon drives too. This will be a topic for another blog post :)

It also seems as if Ioni itself will still set the minimum dimension in the direction the longer card edge connector would go. In other words, there’s next to no space to be saved in the enclosure, just a small extra PCB area on the drive and motherboard, and the extra cost of the slightly longer socket (unless I’m interpreting the photographs wrong?)

Any increase in max current will appeal particularly to the people building force feedback wheels, I’m guessing. I’m also hoping for as much current as possible for my own upcoming product. Ideally we’d like 40A peak, but your summed third harmonic phase to phase waveform modification is brilliant, and also very compelling for us as it effectively promises the advantage of field weakening (extra speed), without the efficiency loss. I’m hoping it will allow us to use a lower Kv motor for more torque per amp without an unacceptable loss of top speed.

I apologise for my ignorance with the next question. Would it be possible to run a 6 wire motor with three wires to each of two Ioni drives, sharing one feedback source instead of connecting the windings as Delta or Wye?

Any possibility of Sensorless or Halls Only commutation with Ioni?

Kind regards,

Jason
