All my best ideas seem to start out that way. Now I have two nice Moog BLDC
motors I bought on eBay, and am thinking of a
I have this working nicely in bipolar 3-wire mode (as shown in the
Youtube video) then decided to elaborate it a bit to 6-wire which will
follow shortly.
The 6-wire version should allow for driving BLDC motors direct from a
P-Port, optionally with some intervening power electronics.
This 3-wire ve

That is it exactly.

There's no SoftDMC driver for EMC2, so that could be the imp
Looks good. I can't listen to the sound until later today.
When you say the performance is similar, do you mean torque, torque ripple,
or what?
Also, I meant to ask previously: What's the motivation for doing this in EMC
vs using SoftDMC? (Sorry if this is a stupid question.. I don't know much
