I have an AC system that runs on single phase 120v AC. The "motor" is a hermetically sealed compressor, fractional horsepower. It has a single capacitor about the size of pill bottle. Based on that, I think the motor is a capacitor start type single phase motor.
What I want to do is use a VFD, or something similar to run the motor up to perhaps 120% of it's rated speed. This is for an experiment, so I only need the motor to work for a few hours, and if I accidentally destroy it that's an acceptable risk.
I've done a bit of research and it appears that this is not a trivial task. However, it seems like if I were able to create a voltage of 120V+, up to around 72 hz, then that should work. Would it not?
If so what's the simplest way to go about this? I'm considering buying a single phase 240v output vfd, and stepping the output down using a 2:1 transformer. Is there a better way?
