These motor are very similar to the Electrospindels 18000-24000RPM.
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 18000-24000RPM version has 750W at 18000RPM and at 12000RPM it has only 500 Watt. These types we are offering are often sold in drilling applications where more power is needed at lower RPM.
