hi
yes surely possible. plettenberg said that a maxximum can shortly produce up to 2kw.
whatever i didn't want to claim that a maxximum is as powerful as a XL feigao anytime with any setup. i just mentioned my experience so far.
i think i ll get a big lehner sometime to use with my warrior. the quality of the feigao did not really convice me that much. and the wanderer 9xl i have here looks very much the same. i am not even sure if they really changed something there. nevertheless they are good motors for what they cost.
a lehner 1950 and the like are in the price range of the pletts from what i saw so far. but maybe i missed some sources.

Yep, the 1950 is not a cheap motor either. But I can highly recommend them! More motor than our MTs ever need.

Well gee. I have my little motor rated at little over 3000wats of power. It was a little more than the plettenberg. :D

I wonder how they match up torque wise though.

with the 2250, you really don't need to worry about that torque issue Leroy....

im pretty sure your 2250 could beat it :027:

2240 already does, so i wouldn't be too worried.. :D

Well That is good to know. I think the lehner 19 series has more torque than the feigaos do. If the motor makes you happy and satisfied why worry about it though. I am just a hard person to satisfy. :D

It is incorrect to compare plettenberg with XL motors and lehner 19 series and up...

Plettenberg motor can be compared with L-series motors. Being 4-pole motor makes it very torque motor but with limited RPM range. That is why not every ESC will handle it with ease. For example BK controllers do not have protection over high RPM (you can destroy batteries or ESC), while schulze controllers do have that (by limiting RPM). When 4-pole motor used you need to reduce RPM supported by ESC by factor of 2 (compared to 2-pole motor) and then do the comparison.

BK and Scultze can run up to 65000 with 2-pole motors
MGM Compro can do 150000 with 2-pole motors

With 4-pole that would be half and half.

Also plettenberg motor has poles in configuration which creates high magnetic friction (while it can be configured to self-cancelling), which can be useful in some applications and bad in others.

P.S. Somewhere I was reading that lehner motor are 4-pole motors is that correct? Haven't had one yet...

im pretty sure they are 2 pole but i could be wrong

@GriffinRU
i don't get your argument. the plettenberg maxximum might be compared to the L series. maybe. from all i read and saw it is pretty much more powerful. but the bigmaxximum suerly plays in the same range as the XL motors.
a lehner 1930 is in the range of a maxximum. the 1940 or 1950 are more on the bigmaxximum level.
yes the pletts are 4poler which poses some problems sometimes.
the schulze controllers can to 63'000 rpm with 4polers and double the rpm with 2polers.
i am also pretty sure that the lehners are 2polers.

yes, lehners are 2 polers. and the thing with the bk's is that it you run a 4 pole motor then your rpm limit is cut in half. which would be 50,000 rpm's. im not sure of anybody that has tried it but the only way to find out is to try it.

My comment based on overall dimensions. Check side by side picture. Plettenberg motor dimensions are closer to L-series then XL. But has extra features in the can design, which makes it run cooler and overall setup makes it run with better efficiency (in limitted RPM range!) then feigao/nemesis/hacker.

Artur

I checked Bk web-site and now they spec their controllers to 100000 RPM for 2-pole motors. (I assume that this correspond to only new controllers with new software and hardware. Because old ones cannot run at such RPM, tested and verified many times.)

So, now which ESC cannot run 4-pole motor?
And how many of you run motor at 50000+ RPM?

Artur

im pretty sure not many people run there motor over 50000 rpm

Well gee, the little motor on the right going in my 1/5 scale is rated a bit more than your 3000 watts of power :D
