I have an older industrial sewing machine that is ran by a 3 phase clutch motor, but only have single phase power coming in. Under normal circumstances I would just swap out the motor with a single phase servo motor and be done with it. This machine came with a controller that can do a host of things, Needle positioner, automatic thread cutting, programmable stitching etc.
We would really like to have the full features of this machine, as a bit of a electrical novice I thought a vfd would do the trick as the motor it rated 220v/550w/2.1a which is under 1hp. What I was told in the sewing forums was that because the controller has a speed control a vfd would not work? I was thinking setting the vfd to fixed voltage but will that not work?
I only have 120/20a running there now but if needed I can run a 220 line to feed the machine.
The path that it takes right now is power into a fuse box out to the clutch motor which then feeds into the controller. Normally without a controller the pedal pulls down on the actuator lever and engages the clutch, with this one the pedal pulls down and engages an actuator on the controller. I do not see any markings on the controller besides a switch to change voltage 190/208/220/240
Here are some photos:

Is this something that is possible without getting into the thousands?
Thanks in advance
