I purchased the following Chinese spindle motor, and got some bad advice on the VFD. The VFD is a KBMA-24D series from KB Electronics, which is obviously incompatible because it will not source 400 Hz.

The motor I have uses German bearings and claims low runout. The specs are:

Product information
Technical Details

Manufacturer: Taishi
Part Number: USTS0811FG
Is Discontinued By Manufacturer: No
Color: Silver
Material: Steel
Power Source: Ac
Voltage: 220 Volts
Wattage: 800 watts
Horsepower: 1 hp

Engraved on motor: 0.8KW 220V 6.5A 400HZ

The VFD the Rep now suggests, again, does not source 400 Hz, and costs nearly $400, so I thought I'd try getting advice from the forum. I would prefer running the VFD with 120V/60Hz input voltage if that is all possible, but if not I can drop another 240V line in my shop. I have a limited budget so I don't want to end up with another VFD that doesn't drive this motor.

have you seen these? https://www.amazon.com/dp/B0775XWYVJ...ing=UTF8&psc=1

i'm not an expert but it can do 400hz and should be able to manage the 800w.

i had one for my 2.2kw spindle but it wasn't big enough so i ahve gone with a 220v version
