  Bingo... Of course there's plenty of apps where that doesn't matter... we'll see them implemented in "bursty" automobiles a long time before we see them implemented in "continuous" railroad traction motors, for example. Its an interesting time to be alive. I'm not THAT old and when I was a kid a generic NEMA 50 HP industrial electric motor took a crane or at least a large engine hoist to lift, more than 500 pounds for sure, but now there are high end automotive motors that I can easily do bicep curls with (like 40 pounds) VFDs are kinda like that too. What used to be a large rack is now a little tiny DIN unit that handles 10x the power.
