My main limitations here are with the amount of power needed, and of course the price. What I'm trying to do is to run a clothing dryer from the USA in another country, without burning out the drum motor again. As I have to replace the motor already, I could either build/buy a frequency converter, or try to find a motor rated for 50hz instead (assuming the dryer doesn't use a transformer, otherwise I might be able to replace that instead...?) The odd thing is that both the manufacturer's website AND the label on the dryer itself list "220v 50/60hz," though the drum motor died prematurely. There's also no warranty since the dryer was exported.
Costs: ~$300USD (motor - required as current one died) ~$1,000USD (the "cheapest" new dryer, if buying locally) ~$3,000USD (cheapest frequency converter I could find >7kVa)
Specifics: Power desired : 220v, 15a, 60hz. Mains power: 220v, 15a, 50hz.
While I can readily find devices that convert both voltage AND frequency for a decent price, I'm not finding anything that converts JUST frequency for less than $3,000 USD; at least, none that are designed for ~7.5kVa and run on 220v. Hence my interest in building one.
While I have had no formal schooling specifically in electronics or electrical engineering, I am quite experienced thanks to the vast amount of electrical repairs I do in my work. I can read diagrams, write my own while examining/tracing circuits, and I am comfortable with PCB's and related soldering.
I'm asking this here, because I honestly have no idea where a better place to ask would be. It's unfortunately not a super-specific question, though it IS an electrical/electronic engineering conundrum.
-UPDATE- After removing the dead motor, I have additional information. The label on the dead motor states: 1/3hp 120v/60hz/6.1A. so even though the dryer sticker specifically shows 50/60, the actual motor isn't "both." I'm now looking for a 50hz version of the OEM motor, though progress is slow.... Thankfully, the motor turns both the drum AND the blower, which means no other moving part will be impacted by the frequency change. If anyone has a "trusted" and knowledgeable source (other than Grainger, whom I'm about to contact) for such things, I'll gladly listen (or read...?).
