What happens when you run a 240V motor at 120V

Be very careful, that motor looks like it is made with Chineseium. (it's on the periodic table right after JUNK) Do you have a problem with having a licensed electrician do wiring for you? I'm sure that there is a way to get the job done properly even without a set of stamped plans by a mechanical engineer. I think that the electrician can get it right with just pulling a permit.

After you make that expensive repair and you still have the same problem, What will you check next?

Perhaps Google can find you a 120V 60Hz version of that same motor?

That motor is rated at 50Hz. Not going to work in this country.

Won't it just spin faster?
Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

Probably overheat and burn up would be my guess. $$$ for a VFD control LOL

I've been thinking about that. The model is YDK-20-4Z. The YDK series motors seem to be used in a lot of minisplits and room air conditioners, you see them in equipment from Carrier and Trane. The 20 is the wattage, this is a 20-watt motor, the YDK-32 32-watt motor seems to be the most popular variant. I don't know what the 4Z means, but I suspect that since it's a 4-speed motor that's what the 4 is. That's what I've been able to decipher. I know that there are 120V versions of YDK motors, here's one that looks like it would be a drop-in replacement, except it's only 16W:
This one is 20W but is YDKS, I think the extra S is for "short," the output shaft looks shorter:
So if I could figure out a part number I could probably find it. At the same time, a transformer is about the same cost as a new motor.

The 50 hz thing may or may not be a problem. Probably not. The motor will run slightly faster.

Probably cost more than it's worth in gadgets to get it running
