Guys

There seems to be some misunderstandings on motors and pole counts.

The magnets on the motor dictate the poll count, not the windings. As far as the cog goes on a motor, that can be the magnet strength in part so a 4 pole can have a lot of cog too.But a higher pole motor will have more cog if the same strength magnets are used. Different magnet strengths are also used to help get desired kvs.

The windings on a 6 pole motor only differ because a 2y 4 pole can have a 2000 kv but a 2y 6 pole motor would have a 1500 kv. So a 6 pole needs to be wound to a 1.5y to get the same kv. This is just an example. The higher the pole count, the higher the torque, But, at the expense of a lower wind. Which means sometimes you can't get the kv you want after you get down below a 1Y. The actual kv differs between different sized motors. I hope this helps.

Agreed. I'm glad someone else said it. I'm sitting back reading this and thinking "wha?" Windings-poles count....umm no. It's how many magnets the rotor has. Something to add to it that I'm surprised no one else has said. This is an observation on my part...I may be wrong, but I've noticed in motors with more copper ("higher end like Lehner and neu) they have letter steel in the windings so it has less cogging. A super cheap motor (think old dynamite) have a lot more cog to them. A Lehner has none. It only has copper in the windings. Just something for you guys to rethink about on the cogging of a motor.

[Brushless55]

Sorry to hear about that man, but I'm sure Joe will make it right.

I'm currently at a ski resort here in Southern California, couldn't miss the first good snow days down here. Luckily though, I brought with me my motors and ESCs to do some soldering during our downtime, and was able to inspect the motors.

I kinda was certain they were 6 pole by how much resistance I was feeling rotating the shaft, quite a bit more than my 4-pole Leopards, which I assume is because of the additional magnets.

Have you had a chance to inspect those motors you are running? You seemed happy with the SSS motors you have, I wonder how many poles they have. If they are also 4-pole, then there is some other things going on that has made them more "gentle" than the Leopard 4-poles.

Some motors are very smooth when turning by hand , 6pole, 4pole etc
some are hard to turn..

has anyone posted any pictures of the motor in question

I know box labeling can be a little off at times coming from China

Then I apologise.
Seems it was explained to me wrongly all those years ago.

For those that believe that feeling "cogging" by hand means anything, remember when Neu splayed the stator in most of their motors several years ago to help the heli guys keep their blades on the hub. Two Neu motors labeled identically would feel completely different when hand testing coggin strength. Lehners are 2-pole motors. Two pole motors won't cog, period - it has nothing to do with "only having copper in the windings"

[TRUCKPULL]

Ok

Then what is the wind on a SSS 4082 -2000kv, 6 Pole brushless motor

"D" or "Y"

This is a must know in order to set the timing.

I don't think SSS makes y winds. D winds require less work to make and don't need an extra solder joint in the motor.

If it has a solder joint inside the end bell its a y wind if not, D wind.

If somebody takes apart one of these SSS 40 series motors and finds that they are 6 pole, post a pic of the rotor.

Really? So have you taken apart a Lehner? No. I bet you haven't. Tell me, if all of the windings are nothing but copper what possibly could the magnets be attracted to so it would cog? Maybe I'm just dumb or something but when I was in elementary school I learned that copper isn't magnetic unless you apply power to it. Now if you add steel to the windings, it gives the magnets something to be attracted to. How could you possibly disagree?


On a side note, I could see where you'd assume what you are on a two pole. I have several here I just looked at and none of them have anything but copper in the windings...so I'd agree most two poles won't cog unless there's steel in the windings. Period.

[rayzerdesigns]

how did we get on motor nd poles when this is a discussion on a boat??

[ray schrauwen]

Its a nice boat. Back on topic!

What is required to be on waiting list? Pre order?

[T.S.Davis]

I've taken apart, Aveox, Lehner, Hacker, Neu, AQ, Proboat, Feigeo, Nemisis, Chilli pepper, Graupner, SSS, every 05 I ever had. What I can remember at the moment. I don't ever remember seeing any steel in the winding. Honestly though it's not something I ever cared about so wasn't looking for it.

I have an SSS at the house I tore apart but it's the 36mm. The surprising thing to me was how much of the can wasn't filled with winding. Then the actual rotor was very small too. By small I mean length. It was like they bought bigger cans than they needed and left them only half full of.......stuff.

On topic again.

Mike, is the plan for these to be available on shelves at local hobby stores or just an on-line store etc?

I'll take apart a couple this evening and post a video to highlight what I'm referring to. No worries.

I talked to mike the other day and he's going to send me a tester when he gets his shipment in. I can run pretty much year round here. I've got a smaller private pond with boueys setup for a race course that I'll be running in. Perfect for this boat. I'll let my son drive my rigger and see if he can beat me. Get my other son to video. I don't get to keep the boat unless I buy it. Which I'm sure I will lol. With what he's told me and the videos he sent me looks like a hoot and would be a nice addition to my collection anyway. Can't wait!

[rickwess]

My preference would be for the boat, less the electrics. I'd much rather add motor (TP), ESC (data logging) , Rx (Spektrum - don't need a Tx) and servo (digital) of my choosing. Hopefully that will be an option.

[ray schrauwen]

Yes, hull and hardware is what many of us may want. Most of us have tx and Rx with motors and escs kicking around.
