Motor heat

[DPeterson]

Like I said I will continue to refute the nonsense.

Nice try Ray - my reference to the trolls is in regards to the few gentleman that keep taking these threads off topic and in the direction of NAMBA P-Limited. Has nothing to do with the majority of NAMBA members.

Glad your the lucky guy that got the revised motors. IMO little late for whom ever supplied you with the proper crises management. Unlucky for the next guy who orders. LOL Ray - better wait to order. Got 2 more motors to purge.

6. Finally.... you are not the only one on this forum who receives pm's and emails, and let's just say that I'm aware of many of the circumstances that have led to this point. I'll leave it at that.

WHAT! You know people? They don't run Namba rules do they? Namba has very little following I hear. I get few messages and texts too. Go figure. We must know the same people.

Ray S, as far as I know that batch of motors that turned me into a raving lunatic aren't on shelves anymore. I still have some in my boats too.

terry I still have my first 2 "bad batch" in my boats..still going strong..and im sure no one calls my boats slow..lol..I have built 2 more p limted boats so had to have new motors..headed to Tucson today..modern time..and of course cat

[ray schrauwen]

May I please, after asking several times, know where you bought these supposed 'new' version of 2030 motor?

Above as Doug pointed out.... luck.....

At the end of the day we are grown men playing with toy boats.
We know from the past that this kind of crap causes more problems than it solves.
If I was a new guy considering getting into racing I would run, not walk in the other direction!

You guys about done with this one?

[tlandauer]

A guy like me who have no clue still don't understand what's the fuss. ( Namba vs. IMPBA) I read every post with admiration (1/2 ). I did learn something important here about motor and that was great.
If I have as many accolades under my belt guess I would be part of the crap. ( The way I look at it is that this is an exclusive club)
Although that will never happen

Ray, I might not be your friend like terry and Darin But I could give you a little friendly advice. With the cost of shipping and returning from Canada, I would wait till about two weeks before you go testing this spring to get them. This way you won't have to rely on their"great cutomer service". What they heck is that? Taking back defective motors is now great?

[ray schrauwen]

rotflmao....
Now why wouldn't we be friends? Thanks for a dose of reality. I was thinking about the shipping aspect but, I just this second remembered our LHS, Great Hobbies and HobbyHobby. They will treat me right in the spring. Thank you for talking me down some, I needed it.

Ironic - not a darn thing wrong with the motors - but yet they got sent back. Read the P-Limited Essay man.

[rayzerdesigns]

they came from tower hobbies, and they weren't defective, but we also had another guy here in phx that did the same thing, if you call them they know what the difference is with new motors, im sure the older batch is fine, maybe not..but it is great they are doing that..but I guess that's my opinion, wont persuade any of the haters..i called them, I paid 6 dollars to send back, they paid for express back to me...im not gonna complain with that..period..if you don't like the 2030 by all means don't run it..but bad mouthing any one that is trying to fix a problem they had is great in my book..im still running my so called bad batch of motors..but building new boats so need new motors..there is a lot of hate going on on this thread and others about this motor, and dougs tp motor..all it is doing is dividing fe more, which isnt needed..but again that's my opinion..i have no problem with people trying new motors, but until they are legal, I wont run one in a race..heck I even haved tried a few not legal motors in my scale boat..but I abide by rules in sanction body that I race in and a member of..doug has every right to try and do what he is doing, whether people agree with it or not..its his right..but bad mouthing different sanctioning bodies cause they don't conform in my opinion isnt cool..if you don't like the way namba or impba runs..you have choices..i will leave it at that that..see all at ww11, and nats..if not..have a great 2015 lets have fun

Get it back on topic please sirs. I believe it was "Motor heat".

[Doby]

Motors should run cool...there, back on topic!

Motor heat part two

OK - the other motor heat thread imploded. I am still curious about a few technical things. My questions have nothing to do about either racing associations rules or spec motor selections. Can we keep it this way please.

I think we can agree - the obvious - motor mass, quality of wire, quality of varnish and wire separation allow us to run a particular voltage through a motor before meltdown.

So - the questions:
1. What is the difference between 2,4 and 6 pole motors relative to heat. Is it a given that a 2 pole will always run cooler than a 6 pole? Also reference was made that once you mix up pole counts in a spec motor situation you loose parity. I have not seen this yet so I am curious as to why this would be. I am under the impression more poles have more torque and less poles are more rpm/efficient. This is not what we experienced when we ran the 2030 against the TP. So now confused.

2. I think this got answered for me already but I will ask it here. Some esc's ask and are programed to run with motors of a particular pole count. The answer I got was that this is mainly for data logging. Is there any other effect on efficiency and or heat generation?

3. I know from experience that increasing the timing to a motor will generally create heat. Is this mainly true for higher pole count motors? My 2 pole Lehners loved high timing. Is this a pole count related issue or an issue across all pole counts?

4. When I tested the TP 3630 motor in my P-Limited mono I tried to burn it down by over propping it something stupid and running it way longer than I should have. As I went up on prop size I could see the boat slow distinctively. What is the technical reason for this? I would have expected a faster boat or an out of control boat and then a puff. I am building a new mono so I didn't care.

Looking forward to learning more.

1. poles are the number of 3 way electromagnetic winding a motor has..not really condusive to heat build up, but basically more poles equal more torque..in equal motors

[rayzerdesigns]

2. a speed control shouldn't make a motor better or worse..there are defininately differences in the way they are built..but that is internals..shouldn't make a difference if more poles or less
