Since we decided to stay in Thailand we want to bring over the personal belongings that we left in the states. Among them are some 110 appliances (a big kitchenaid mixer and a table saw mainly) . For this I had bought a few heavy duty transformers to step up from 110 to the 220 here.
It has worked good on a small appliance we have but I am not sure if I will lose anything when using the bigger appliances.
We are shipping over stuff so I have room but if the appliances won't function properly I might as well buy here.
I like the ones I have, good quality (vs Thai made stuff) but if their outputs are reduced I might as well use Thai made.
Any experiences, thoughts suggestions welcome!!

Need to know just what the rating in watts or KVA that your transformers are, and the rating of the appliances.
The other thing is the frequency difference, 50 Hz here as against 60 Hz rating of your appliances. Basically things with motors in them are more affected by the lower Hz, they will run slower. Frequency cannot be changed with a transformer. Along with running slower they will draw more amps and could over heat.
Are the transformers rated for 50Hz or 60 Hz?
May you be in heaven half an hour before the devil know`s you`re dead!
Just to add to this; if you have the shipping space anyway, then as the appliances are already paid for you do not have much to lose by bringing them along. If the table saw is a good quality unit then you could always change just the motor here if it burns out.

You don’t give much info but if your table saw really is a substantial one with a belt drive motor its usually just a matter of switching 2 wires in the motor’s junction box. USA 110 volt single phase motors are usually wired with comutater and armature in parallel and you simply switch 2 wires to put them in series for 220 volt operation. Real saws with heavy slower RPM motors at 1½ HP and up are usually set for the more efficient 220v as all USA houses and shops do have 220v circuits for their cook stoves, water heaters, air cons, heating, etc. But pot luck if its a cheaper light weight table saw with a high speed gear head motor.
Fot your houshold things with home use duty cycle expectancies I would not worry about going down from 60 cycles to 50. I have done it with lots of big and small hand tools, my big 12” saw, 18” planer, and kitchen appliances. The difference is usually not noticeable. What is not OK is usually stuff with computerized contril circuitry like some hi end sewing machines, stuff like that. But what does almost always happen is that sooner or later somone will plug your bastard stuff into the wall and a millisecond of that is all she wrote. Not helpful that Thai and USA plugs are identical, so anything valuable is more safe if hard wired right into the transformer
Your Kitchen Aid mixer will probably be OK with a transformer. What little you paid for it in the USA vs what a Kitchen Aid costs here justifies the experiment. But as an example of relevance we bought a heavy duty commercial mixer in Bkk China Town 2 times bigger and 3 times heavier than a Kitchen Aid at less than ¼ the Thai Kitchen Aid price. And almost all of my 110v hand tools are a waste of shelf space - long ago replaced by local items as packing around heavy transformers for any little job is a serious pain in the ass..
Oops - shud have said a motor’s field coils can be wired series or parallel to change the motor’s voltage. It is smaller universal motors, like in hand held power tools, that field and commutator can be series or parallel

Thanks Hin, that helps! I've already replaced hand tools. I had figured one transformer in the workshop, one in the kitchen, both mainly dedicated to those two appliances. Lugging them around, as you said, is not much fun!

Forgive my slight aside, but without looking at the thread itself, only the title, I've spent the last couple of days wondering how on earth anyone could manage to accumulate 110 electric appliances...

Sorry mate, but you need to go back to school. If you connect a universal series motor as you suggest it then becomes "shunt" connected and will rapidly burn up. Regardless of the voltage, connected in series the line voltage drop across each section, armature and field, is roughly 50%. Connected in parallel the full 100% line voltage would then be applied across both the armature and the field.

Isn’t that essentially what I said - parallel connected 110v universal motor - use it on 220v by changing to series connection which drops 220v across the mptpr by 50%.

No, it's not. You have not understood that which I posted. By definition, a series motor, universal AC or DC, is wound as a SERIES motor for a certain voltage. You cannot connect it as you are suggesting. SOME universal DC series motors were wound with a compensating winding to allow them to run better on AC, but they are still single voltage. They are still series connected, and very rare now.

These are ones we have had in storage when we left the US.

Migrant, you overestimate my technical intelligence. I thought you were referring to 110 individual devices, as opposed to a handful of 110v appliances. Of course, now that the thread title has been amended, it is all irrelevant!

Ahhh I see!! Now if I mentioned my wifes shoes, or purses, that could be 110!!

I hate to throw water on this whole "import" effort but it just doesn't make financial sense to bring anything over from the U.S. All the trouble listed above is one part of the problem. The other is that you could replicate everything you want to bring from the U.S. in Thailand for the same or less than it would cost to bring it over here. I deal with all the importing for the company I work for and see the cost figures.
I hated to give up my 1909 66" Roll Top desk and many other antiques plus tools but came to the realization that they are just "things" but more important than that were the relationships I forged for my 67 years in the U.S.
A friend moved a whole container of his 25 years in Thailand to the U.S. and has stored it in a locker in the U.S. until he now can unload it in a house in N.Y. 4 years later. Total cost of the move has turned out to be substantially more than it would have cost him to purchase the items in the U.S.
When you make a move this drastic you have to come to the realization that your starting a new phase of your life that will be different and require new and different "things".
