The new Luminary motor controller as seen at NI week '08. It seems stable, there were a couple of demonstrations running which produced high EM spikes (motor reversals at high current), none of which seemed to upset the controller. Now, it wasn’t me that was there, it was my dad, but I’ve heard that the chop frequency is barely detectable unlike the current WAAAAAAAH of the current speed controllers.
disclaimer I’m not saying the current speed controllers aren’t good… I still really like IFI stuff and I’m sad to see FIRST pushing them out of the picture.
