I read that document & all I see is referance to "6 step block wave form" to drive the motor....still 3-phase comutation by any other name...the 6-block control wave is a simpler form to replicate ellectronicly than the smoother "sinusoidal" wave that many are searching for. (normaly created by AC electricity generation)
Lots of equipment is fussy regarding the wave pattern & higher end power inverters will "replicate" a modified sine wave much closer for just that reason....
your using a controller of your own design or an off the shelf unit?
Or am I missing something?
Trial & error is all I have offer if there is more complicated ellectrical theroy involved
I am sure a more knowledgable E-guy will be along shortly to help.
