Variable Frequency Drive, 110VAC 50/60Hz 1500W VFD Inverter Converter, VFD Inverter Frequency Converter (Single-Phase Input, 3 Phase Output)

I bought this to control the 230v three phase motor on my lathe. It works exactly as it's designed to. No complaints other than shipping was seemingly and endlessly delayed.

I use it for variable speed on my belt grinder.Input voltage from wall receptacle is 120v 60hz single phase.Motor is 1.5hp, 220v, three phase, 60hz max frequency, 3600 max rpm.When the VFD is programmed for a 10hz to 60hz frequency range, I get 600rpm to 3600rpm from the motor. This is perfect for my intended use.It was pretty easy to wire the VFD to the motor and electrical source.I will eventually add an external remote potentiometer and fwd/off/rev 3-way switch for convenience of use, but I haven't figured out how to do this yet. The VFD instructions aren't provided for doing this (programming yes, wiring instructions no), but there is a connection bar available on the VFD for wiring to remote controls. I will research on youtube for wiring instructions.All works smoothly during bench testing across the full rpm range at no load. I haven't mounted it on the belt grinder yet (no-load tested only) but this will be easy because the motor frame is 56C, the same specification as the old one-speed 3450rpm motor. The old motor ran too fast for my intended use, is why I changed to the VFD and 3-phase motor. I could have bought a 1725rpm replacement motor and changed the pulley ratio to the belt grinder to slow things down, but I wanted variable speed.

VFD worked good for about 3 days, then a puff of smoke and now it will not even light up. I programed it for 50hz and 6amp even though my motor is a 7amp, at 60hz. The overheat shut off feature is apparently non existent on this VFD, they lied to. Make a selling point. And there idea of a refund is only giving you HALF your money back.
