Sold Used TC9 Motor w/Full Copper Treatment

[ciaonzo 5,000+ posts]

I pulled this off of a prototype which might explain why it has TC7 steel on 1" TC9 slugs. Regardless, it's nice and strong, and would be perfect for anyone looking to build a low inductance/low distortion driver. The Qes figure for the driver was .423, the BL figure was 18.7 (Re of 3.12), and with the full compliment of copper (ring and sleeve) the Le was sitting at .62mH rather than the usual 3 to 7 mH seen in TC9 motors without this kind of treatment. The coil helping to generate those figures was a 3" four layer aluminum round wire with a WW of 2.25". You can use a slightly longer coil if you want, there's plenty of room for a 3" stroke with this motor. Power handling should be right on par with any other TC9, with consideration given for your choice of coil. Inside diameter is 2 7/8" and outside diameter is 3 3/8".

Looking for $100 shipped CONUS.

hey if you dont mind my thread jacking for just one more question..what exactly does that mean..lower inductance and reduced THD??

I don't want to be rude but this topic is quickly cluttering my thread. Plenty of info out there waiting to be found!

Buy the pair before I throw my LMS coils in them and make some ultra-low distortion IB beasts!

Whats the diameter of the top-plate ( i didnt read through the pages so fuss at me if necessary)

No fuss at all, did you want the outside diameter for the coil or the overall diameter of the top plate? Coil OD is 3 3/8", overall diameter is 5 3/4".
I can clean these up for you too, Phill. Obviously the gaps, but also the glue on the top plate and such.

Whats the pole OD?

Whats the pole OD?

The physical OD is 2 7/8" but the actual magnetic OD is 2 11/16".

Sweet, thanks Phill. She'll ship out tomorrow.

No rush, getting a custom adapter plate build for a top assembly I have, still awaiting a quote so it'll not be here very soon lol.
