These motor are very similar to the Electrospindels 24000RPM.
Only real difference is that they have a lower base RPM. The base RPM is 12000. Since the TeknoMotors have a linear V/F curve this also means that a 750W version of this motor really has 750W at 12000RPM. A 24000RPM version has 750W at 18000RPM and at 12000RPM it has only 500 Watt...
