Personally, this is what I think about the Neus:

They have pretty low turn counts compared to their KV ratings. For instance, the 2.5 turn Neu 1512 2d has about the same kv as a 6 turn XL motor (and same delta coil configuration). So, this leads me to believe that the Neu has a highly inductive coil setup to compensate for lack of wire resistance. High inductive loads can be VERY difficult to drive due to the phase angles of current and voltage when driven by an AC signal (which is essentially what PWM DC is). It also doesn't help that the Neu coils are wrapped around a core of sorts to concentrate the magentic field for a stronger, more tightly controlled magnetic effect. When you add a core to an inductor, you immediately change its inductance value substantially.

I don't think the MM has the software to deal with these types of motors. But the Quark apparently does. Maybe the Quark's programming compensates for a "difficult" motor by adjusting timing, switching frequency, who knows? After all, both ESCs use the same FETs, so it's not a electronic capacity issue. We also know that MM's problem is not because the Neu is a 4 poler, because people have run 4-6 pole motors with apparently no issue. I think MM's problem is strictly in software. We also have to remember that the MM was designed specifically for MM motors. Since they are 2 polers, it only makes sense that most other 2 polers work as well. However, I bet if there was a two pole motor built similar to the Neu with low turn counts (yet typical KV rating) and a cored soil setup, that 2 pole would have similar problems as the Neu.

To be clear; I'm not knocking the Neus by any means. I LOVE mine and it works great on the Quark.

Ok thanks and strangely i think i understand that, you are saying that the inductance coil changes the kv like more winds do, or changing the winding config, right?

[BrianG]

I don't think inductance by itself changes the kv, but a coil wrapped around a core of some type might since it concentrates the magentic line of flux, thereby directing more magnetic energy to the rotor. The core also changes inductance though.

[crazyjr]

What i meant is, the inductor/coil fools thing to run slower. Like changing the magnetic field so it feels like a higher turn with more windings but less wire so it would still be light

My initial plan for the R1 Pro was going to be to put it into an 1/8th scale truck. I understand that this would be running the esc out of spec and wouldn't be covered by warranty. Warranty issues aside, what is the R1 Pro capable of in real world applications? What is the actual current limit? What is the actual voltage limit?

Thanks guys!

Yes I work at Tekin, it's our family business.

I wouldn't run the R1 Pro with anything bigger than 4s. It wasn't designed for Monster Truck use, like the R1MT will be. Actual current limit is 600a peak per phase and actual voltage limit, we rated it at 12.6v. You saw the video, that was on 16.8v with the BEC disabled.

Good thing you are online! welcome to RC-monster, can you please shine your light on this; I was wondering if it would be wise to use transil diodes over the three motor phases? since fetts are kind of allergic to over voltage, and the reserves in voltage are limited?

[captain harlock]

How long will it take befor the MT comes out?

The Prez also said he would not mind making a HV version of the R1MT.

What's your comments on what he said?

[jollyjumper]

when does it come out?

TY, thanks for the straight forward info. It sounds like the current handling isn't the problem (for 1/8 scale application), but rather the low voltage handling.

I'd be willing to try an R1 Pro in an MT on 4S. What is your repair policy (cost) going to be to repair an R1 Pro if/when I blow it up? Are you guys going to have a flat rate repair fee, or will it depend on what smoked?

I really hate to sound like I'm going to jump right in a start off abusing the equipment, but it's what I'll have to do, since I don't own any 1/10 scale vehicles.

BTW, I just wanted to mention that the guy that owns my LHS speaks very highly of your products. Since he's around all sorts of makes and models of equipment, it is real praise when he says that one line of products is better than the rest.

How do you fool physics/nature?

You are not fooling anything, it is what it is, because that's what it is.

Brian: About the Neu's, they are 4 pole right, so double the amount of poles, you need to roughly cut your number of turns in half, don't you?

LOL, appearently you haven't been around our forums too much. We do alot of things we aren't supposed to. We promise to do alot of "post-beta" testing for you.

:o

Nope. it would depend on a Wye or Delta wind.

What i mean is not actually fooling, but with inductors/ coils you increase the fields so it looks like more turns with less resistence

Same configuration I mean, IIRC, the XL's are Delta wind?

I emailed Tekin the other day about the R1MT, and this was their reply:

Really don't have a lot if info right now as we are still playing with it.
The one we used in our video was our R1 Pro which can handle up to 14 cells
and a 5s lip o pack. The MT version we are looking at and testing will be
able to handle 20 + cells. The final version could be different but that is
what we are playing with right now.

This is really good, because all this can mean is that the R1MT will have even more capabilities than 5s.
