I recently bought a Craftsman 109.0703 but the catch was that the motor is on loan until I get my own motor. I looked at VFDs but decided that they were too complex and expensive. My budget for a motor is $250. Watching a You Tube video I learned that there are $100 VFDs out there. Intrigued, I did some more research. First, the motor specs for the Craftsman 109 are:
HP: 1/4 or 1/3 HP
RPM: 1725 to 1750
VFDs use 3 phase motors. A motor that is within my budget is the Iron Horse MTR2-P33-3BD18. It is a 220 3 phase motor that is 1/3HP and 1800 RPM. close enough to the 1750 Craftsman says is needed. It sells in the range of $182 plus shipping. They are on back-order right now and it takes a 5/8" core pulley. The specs say that the motor pulls at full load (FL) 1.4 amps.
Just bought a 5/8" pulley for $14 off of eBay:
The VFD I am considering is the Wisoqu VFD Variable Frequency Drive. It takes 1 phase 110V AC in and puts out 3 phase 220V AC. Cost is $116 on Amazon. It says that it will handle 1,500 watts whic is either about 4 amps at 220v or 2.3 amps at 120v. Either way, both are under the 1.4 FL amps the motor draws.

So for less than $340 I can get a new 1/3 HP motor AND a VFD? What am I missing?
Thanks!
