The limiting factor is mostly the lamination thickness at 0.5mm. For your example, at 1000rpm, the fundamental frequency would be 383Hz.John in CR wrote:It took a while for it to click for me, but since they're designed for 48V or less operation it makes perfect sense that lesser iron is used. It's not needed.
