TBH, I didn't think about low rotational speed wind turbines. Yeah, it may be a big thing for those.
"Electric drivetrains" can mean anything from an excavator moving at 5km/h with 3m large wheels in a frequency of less then 0.2Hz up to extreme race RC vehicles, at 100km/h with 5cm wheels at ~100Hz. A car wheels go barely over 1k RPM, but I don't really expect them to do anything useful for those.
