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.

Bill of Phoenix Engineering says the mounting hole dimensions of the SOTA DC motor are very, very close to those the Hurst VPI uses, and can be swapped easily. But there is also the matter of electrical conversion, about which I don’t know and myself need to find out. I would love to convert the motors in my Aries 1, HW-19 Mk.3, and Townshend Audio Rock Elite.

@mantistech,

On my motors, the info is on the bottom of the motor itself. You should be able to pull it out of the housing enough to read it.

The SOTA motor drawing shows 2 sets of wires 1 of which seems to not be used. My TNT motor has a captured cord, not an IEC connection. I wish there were some basic instructions. If just attaching wires I'm in tomorrow to buy one. 

Anyone actually have one?

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.
