Upgrading stepper motor for 80mm Spindle
A stepper motor usually does not struggle for life. If it has to move against a force that is too high, it looses steps. The controller has the ability to recognize that. Also Onefinity stated here that a heavy spindle using 80 mm mount would be no problem. The 80 mm mount has not been released without longer testing.
How do you size a VFD?
Sizing. VFD sizing should always be based on motor current and voltage, not hp. Let's begin with the basics by learning how to read a motor nameplate. The nameplate in the main picture shows that motor current is based on the input voltage: volts (V) 230/460, full load amps (FLAs) 13.4/6.7.

VFD's and MOTOR STARTERS | Information by Electrical
Jun 11, 2015. #2. VFDs are often applied in lieu of variable gearboxes. It is just one application of VFDs. Electronic gearing is a lot simpler than variable gearboxes, and generally a lot more reliable. They are also often applied where the mechanical system cannot tolerate the shock of a motor starting across the line.
VFD Buying Guide
To properly de-rate your VFD to act as a phase converter for one-phase incoming power, start with your motors FLA. Multiply the motor FLA by two and select a VFD rated for twice the motor's FLA. For example, if you have a 10 HP motor with a FLA of 28 amps, you'll need a VFD rated more than 56 amps and around 20 HP.
