Roadrunner reapearance


I saw on the latest edition of Analog Planet on MF’s video of the show he attended that at the SOTA booth, they had a working product of the Roadrunner w/motor/pulley as a drop in for a VPI. Anyone here have more info or even better, have one in use? It was reported it is now a product for sale @ $1k. No mention of it on SOTA’s website.

Give SOTA a call, I hear they're great to deal with


I got an email back from them saying a screw driver is all that is needed depending on motor/housing configuration. That seemed too good to be true so this morning I got more adventurous and removed the bottom plate of the motor/housing. Looks pretty simple wire nuts with a few electrical bits (cap/resistor I think) up to the switch and in turn to the motor. So maybe drop in the motor, fish some wires through and some SOTA specific bits to make it change from 2-phase to 3-phase...though I'm not very electrically inclined I get there is a difference.

They also said in coming weeks a VPI specific options for IEC plates and pully options.

I'm still not clear on what is the difference is between the wall plug and the motor base. If there is a wall wort and small wiring then I guess in the case of an IEC connection something is needed. Mine is just a standard cord passing through the SAMA housing. No removable IEC connection on the outside of the housing.

Long time reader of AGon forums but never posted. So I can't seem to figure out how to post pix. As they say worth a thousand words. I've got a round motor on top which sits under a round decorative plate covering a black, square plate with 4 holes about 2" on center. Wires run to the switch which runs to the "stuff" at the bottom in the top part I mentioned in this post.

Never mind on the above...I'm an idiot. The PSU is what handles the power to the motor. SOTA has been great at answering my questions. All the wiring from SAMA to wall goes away because the new set up would be:

Wall plug >> Wall wort/cord >> PSU >> SOTA Motor >> Belt >> Platter


I believe the only function of the VPI, housing once converted, is height and weight.


 Depends upon what is going on with the wall wart, but in general I would guess that a wall wart is not compatible with the Phoenix engineering system.

That is direct from SOTA. Like I said they have been great at answering my emails. The Condor PSU gets it power from the wall wort which in turn powers the SOTA 3-phase motor. Here is the info form the email.

As far as installation goes, you'd have no need for that line to the wall. The Eclipse motor gets its power from the Condor PSU, which is neatly run in one line with two disconnect points. Installation is very straightforward - drop the motor in and just run the line to the Condor as you please. The condor will sit in the black box shown on the website, and get its power from a wall wart, as it needs 24VDC power.

@mantistech-


The 3 phase motor from SOTA is a low voltage motor (24V); the standard VPI motor is 115VAC. The Condor controller is powered by a 24VDC wall wart and produces 3 AC waveforms for the motor, the frequency, voltage and phase depends on the speed and load of the motor.I saw your pics on the VPI forum. The Eclipse motor has 3 flying leads that are normally soldered to a 3 pin male chassis mount plug. The Condor has a cable with a 3 min female connector. You will need to make up a short cable to replace the captive AC cord you have currently. One side of the new cable will connect to the 3 wires on the motor using small wire nuts inside the SAMA housing, and the other side will need a connector like this:

soldered to the 3 wires of the new cable and will mate with the 3 pin female connector of the Condor. The wire order is almost immaterial, the worst that can happen is the motor runs backwards. If that happens, swap any two of the three wires and the motor will turn correctly (you can also change the motor direction in user program mode on the Condor).
The Condor/Eclipse motor cabling can be seen here:
