OEM source for VFDs?
OEM source for VFDs?
(OP)
I was tempted to ask this question to the smart fellas in the "Single Phase Motor VFD" thread, esp. during their rants on OEM using VFDs. But, I'll bump it up one level.
We are an OEM. We are in need of a source for OEM'ed VFDs. Only a few thousands a year, so no it's not a 480V, 3HP hair dryer
although.....
My question is that where do I start? Been googling and googling..... calling some rep's here and there, but hasn't gotten much of a nibble. Must be fishing in the wrong spot!
Can someone point me to a few companies that would be interested in working with us on this? Maybe it's your company?
We are in Southern Cal.
Much appreciations in advance!

Or are you wanting a tweaked one? (gack!)

I don't want to dissuade you from posting but this sort of email tends to attract an undesirable amount of attention to Eng-Tips of sales folk selling their wares.
If you want to talk to a drives company with 'a few thousand' drives then I would google Variable Frequency Drives and contact the many hundreds of companies who appear.
If your enquiry is of interest then I guess they will beat down your door.

Actual manufacturers;
Vacon
Parker SSD
Invertek
Yaskawa
AC Tech
Delta
I'm sure there are others but I can't recall offhand. Most of the big electrical suppliers (AB, Cutler Hammer, Automation Direct etc) don't actually manufacture the VFD lines.
I would try Parker SSD in Charlotte NC or AC Tech in Uxbridge, MA first. I believe they both have engineering and manufacturing in those locations so they might be more likely to work with you.
Vacon bought TB Woods VFD division a little while back and they also have manufacturing in Chambersburg, PA so they might work with you.

If you tell us the size of drive and what you are using it for maybe we can add a few or exclude a few.

For starters you instantly lose all bargaining power. Just like going to a car dealer and not buying an available car but wanting a different color, etc..

Perhaps a bit more explanation regarding why a custom VFD is required...?

I can't believe I forgot ABB and Control Techniques aka Emerson though.
It still goes back to what the OP is expecting. Hopefully, he's just looking for the best volume pricing and not on something like a 1hp VFD.
RE: OEM source for VFDs?
Those that I have seen are not only a VFD - they are the complete control center, often with specialised interface and an integrated control panel with all the symbols that are needed and "human friendly" for that application. There are also transducer interfaces and safety features that are hard/impossible to find in any standard OTS VFD.
Re manufacturers. Do not expect the big companies like AB, ABB, Siemens and the like to produce these. They won't even talk to you. In fact, quite many of those companies outsource their production to companies like Invertek (well, perhaps not ABB and Siemens, but many other do).

Seems a so much nimbler design that lets someone shop all the makers and suppliers and never get held over the barrel by whichever one decides to do a custom.

This is true for all white goods producers. Pack all functionality in a compact, optimized package and see to it that cables are kept to a minimum. Carrier, Electrolux, Whirlpool (if they still exist) all do that. I do not really understand how you mean it could be done otherwise.

True Skogs, but this is only a few thousand a year in this instance. A COTS drive with some on-board logic capability or a COTS drive with a microcontroller running it would probably be more economical than a full custom design. The reverse logic would apply if the volume was much higher.
We're all speculating until the OP gives us some more information. Where is he...

RE: OEM source for VFDs?
Cost for a semi-custom design, which it usually is because you build on existing designs, is not as prohibitive as one would think. Much of the schematics can be reduced to one set of PCB description files. That is a benefit seldom considered.
Believe me. Been there, done that for many years.
