Default Big electric motors and little VFD's

Or you can connect just one set of windings, and voila a 1/4 hp

Do the VFD's have any provison to sync two together? If so, you could use
one on each winding set....

NEVER, EVER, try this, unless you like BIG sparks! There are modular
VFDs, usually in hundred HP sizes, that can be paralleled and synched
for larger motors. otherwise, they will not tolerate this AT ALL!
