I’m not an expert, but I don’t believe there are that many motors that spin at 600k RPM (= 10kHz), and definitely no large ones. That is absurdly fast. Modern turbochargers are some of the fastest-spinning off-the-shelf things your average person can buy, and they normally top out below 200k RPM (and only the smallest/lightest turbines can spin at 200k RPM). If there does exist a 500k+ RPM electric motor, I would be surprised if it was larger than a few mm. |
