One thing I have not seen mentioned yet is the need for the magnet wire in the motor to be "inverter rated". Most modern motors are, but older ones are not. If the wire is not up to the task the insulation on the motor windings will eventually punch through from the switching transients and you will be replacing the motor or having it rewound.
You can find VFDs in smaller sizes up to 2HP that will run a 2HP motor off of single phase. It must say so in the specifications. I have a 2HP drive on my South Bend lathe with a 2HP motor. It worked great until the insulation punched through. I did not know about inverter rated magnet wire at the time. Lathe is WWII vintage. Now it is a boat anchor. Motor is two speed, hi speed is 825RPM. Replacement motors not available. The old man who rewound motors by hand for the oil fields is long dead, so someday will have to take on that project myself. Mean time I have a Taiwan made single phase motor lathe that does what I need.

An improperly torqued capscrew on an engine head or a shear bolt that is too hard on the driving shaft of a bushog can create havoc and make an expensive and uncalled for repair. Let�s examine the purpose and design of these fasteners in order to ensure their proper use. Fasteners are probably one of the aspects of mechanics that is given the least amount of thought.
