its a short top plate

9 all the way

sweet, taking 3k pretty well so far //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

the gap is narrower than a typical TC9, at least it looks like it, 1" slug Y35 will fully saturate a 3/4" 1010 top-plate so after the 1st slug there its a clearance thing lol. Gap that tight would help lower Q though if the coil is dense enough to make good use of the extra stout flux field.

I've always read that the RLp was a variation of the TC9 motor. I'm no TC expert though. Any of you tc fiends have a TC2+ motor laying around? //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

got a C in physics in college, u kinda lost me

Excellent writeup, should be stickied.

I have a spare TC2+ with demodulation circuit

Good info. If this was here a few days ago I could have deciphered what motor my Evo was. I read that it was a TC2 and a TC2+, but had no definitive answer besides what Shane told me.

I have what seems like a dumb question, but with XBL^2 its obviously an acronym (I know what it is, but Im not going to clutter the thread with that since its irrelevant to the TC). Is there a particular technology that TC stands for or is it just derived from TC Sounds name?

So, you think the Qes/Qts would be the same if I took the 3LM off of my LMS4000 and replaced it with a TC9? Gap is exactly the same between the two. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
Q would definitely be lower with the 3LM, that's the reason the Q is so high on the SW8000's. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

If magnets had the same charge, Q shifts should be minimal, and I'd like to point out that the LMT from the RL-s line has a tc9 top-plate and a qts over 1.00 lol. My Old school TC3LM 4K's have the exact same Q as my tc9 lms drivers

hmmm, so the 2nd/3rd puck is overkill, but used for clearance on most motors with 3/4 TPs(y35 mags) given the pucks are relatively wide? This would make the 3hps stronger with more saturation? I dnt know much about this stuff, but i used to read a little about farromegnetics, etc.

Insult to injury... TSP's from my LM10D2 (the gen one tsp's are from the sub in my avatar)

the 3HP makes use saturation wise of the top 2 ferrites

Magnetic coupling is a neat thing, demonstrated well in the graphs in the link posted a lil ways up.
