Yep Cartridge and motor setup would be too heavy but we can have custom-built water-cooled ATC electro spindles with BT, HSK, or ISO tapers in usual sizes 20,30,40,63,100, etc with power ratings from 1.8Kw up to 40Kw with speeds and torque ratings up to 60K and 120Nm.!

So yes having an ATC BT30 with 6k-8k rpm is no problem, either flanged (cartridge) or straight body spindle type. Can even have with encoder for ridged taping or orientation and thru coolant.
