Plettenberg vs. Neu?
 

hey everyone,

i was wondering, how does the Plettenberg Bigmaxximum stack up against the larger Neu motors in terms of top speed, torque, i guess just overall power? I'm looking for an absolute killer brushless setup :mdr:

thanks in advance

I personally don't think a Plettenberg would come within a mile of a Neu 1521 on 8S with a MGM 120/32...

Well, first of all, take into account the mass of the Pett. and the 1521 and compare the Kv., then you should be able to make some assumptions about peak power output, as well as which would have more torque. For the same Kv. though, the 1521 should murder the Plett., even a 1515 should be more powerful.

The Bigmaxximum has 6 poles and it will have more torque. Same with a Mega Motor 22/45 or 22/50 series motors as they are also 6 poles.

little video that is on the net

Holy feck, that really is a powerful motor. What people forget sometimes is that the Plett is one size, one Kv (unless you get one specially built to your needs), so it is unfair to compare it other motors which come in a varietty of sizes and Kv ratings (Neus in other words)....

I would rather have a Plett, just for its looks since its power output is more than I could ever use sensibly :D

The Plet Bigmax also has a fan to keep it cool.

Yeah, I seem to remember someone saying it needs to be overgeared in order to keep it cool, which is odd but overgearing does result in a cooler motor/hotter esc with Feigaos, so.... whatever lol. The fan does look rather cool one there, I must admit, whether its really needed or not.

Right, I forgot that a Plett. is a 6 poler.

How much does it weight?

How long is the rotor on it?

It must not have the same manufacturing techniques as higher end motors like Neu/Lehner, such as segmented rotor, and the quality of the core material.

SPECS

I believe the rotor isnt segmented, but it is kevlar wrapped (maybe). Still, much better than a Feigao, but not quite up there with Neus & Lehners.

The Pletts seems to be up there with Neu and Lehner. They are used in some crazy high powered boats. I the Extreme and it is "extreme" fast.

Kv2300 too I should add. That is a kevlar wrapped motor, so quality isnt the issue, just designed a bit differently. Not short on power though, thats for certain.

Looks to be around the same power as a 1515 motor, judging by the rotor, and the weight of the motor.

Is there any Eagletree data on these motors?

ok, so the general thinking is both... :neutral:

reason i was asking is because i just aquired a 'grenade' ESC for a pretty reasonable price, (schulze 18.97 kw) and it is supposed to go well with the Pberg, but now the MMM is about to be released i thought maybe get the Pberg and run with the schulze until the MMM ESC is out, then change to that.

But if the Neu's are more better :mdr: than the Pbergs in general, i might as well just wait for the MMM... i'm lost

thanks for the help, any more feedback would be appreciated

Geared appropriately, either one should suit your needs just fine. Just watch temps and adjust accordingly. Neus can run great up to and over 40k rpm, but don't know what rpms are considered "ideal" for the pletty's ("Max" rpm is not necessarily the "ideal" rpm).

They say the Plets are capable of 70K rpms, but that is just what the rotor can go up to. When and if my controllers gets done, I will buy a Plet just to see how it does.

Yeah, I can see tht Kevlar wrapped rotor being capable of higher rpm's for sure, but I am sure 70K's is not practical, anyway you look at it.

With the Plett., you are basically limited to the one Kv. of 2300 like Niel said. With the Neu's, you have much more diversity, and I am sure they are more efficient as well.

The Neu 15xx series is supposed to get up to 60k rpm, but again, that is probably the rotor/bearing limit. I don know the Neus don't mind higher rpms at all, and are quite tolerant to improper gearing (to a point)...

Oh, I know... they are a 'dream come true' motor, they don't care about gearing, and love the rpm's, unlike others motors, typically (up to a point like you said).

I would like to get a 1500Kv. Neu and test it out on 40 volts for 60,000rpm operation in a MT application. I think a 1509, to keep the current levels in check.

I ran my Neu 1521 1y with 10S lipos and it was incredible. I also ran a few times the Align 600L and I have to say that the Align had more torque. I could do wheelies with my BPP truggy, but I was using a 100A 10S controller that had incredible throttle response. I'll see if I have time to make a video of the Neu 1521 1y with my 10S lipos.

i've been using the maximum with fan (not the bigmaximum) in my revo with great success... never gets hot and insane power... to top it off, they are by far the best looking things you can put in a car...:yes:

I have to agree with abiye on that the pletti's are definitely the best looking motors available. However, I haven't had experience with the Neu or Pletti so I can't help you decide which one to get.

IMO, I think the Neu's are better looking... come on, how can you beat the look of that pitch black finned can like that. :intello:

i agree with abiye, love the look of those Plettenbergs :mdr:

imho the plettis are just awesome motors. :yes:

Yeah, they are nice motors for sure.

But i prefer Neu. They seem to be more efficient and broadly available in the US.

Once castle creations launches their Neu/MMM combo the brushless world will change.

if i was living in the us i would probably pick a neu too.
if they are more efficient....hard to believe.
as the mamba max works great with a plettenberg i hope the monster version will do the same. so that will hopefully be a very nice and broad usable controller.

I'll take the one on the right, thats plenty for my needs! Price wise, ICare-rc sells the BM for $347, whilst the M with fan is $279. So, a bit more pricey than the Neus, but nice motors all the same.

Those motors are sexy, why the need for a fan though with those huge fins on it?

Plettenberg Big Maximum (HP 220/40/A2 S P4 Car)
is a 4-pole motor.
bearings are rated at 70000 RPM, but not the motor efficiency or power...

Motor specs at 18V:
Power - 1271W
Current draw - 70.3A
RPM - 37688
Torque -28.9Ncm
Efficiency 89.8%

max efficiency (91.5%) at ~45A / ~40000RPM / ~18Ncm

Motor can be pushed towards 2000W but efficiency falling dramatically, though great cooling system keeps it from falling apart.

I think the Bigmaxximum is a 6 poler motor. If you look at the first picture on this site http://rc.stuurmijmail.nl/Bigmaxximum/index.html you can see 3 bumps which are the magnets and that is half of the rotor.

I will trust Plettenberg catalog :)

They are only mentioning the Maxximum. The BigMaxximum is 6 Poles.

You can get HP220 series motor with 4 or 6 pole magnet, but I thought that 6 pole was not for cars, but for planes and helis. It would be worthwhile to check that.

On the other hand it would be hard to imagine schulze ESC running 6-pole motor at 70000 RPM, while heli's versions were limited to 35000.

Some ESC will do the 70K rpm with a 6 pole motor, but that would be insane (I got to try it one day LOL). My Plet Extreme is 6 poles and it made my TC3 faster than a fully loaded HPI Pro4 with a Novak 3.5 system in it. I used my MM with 11.1v 5000mAh and the 11.1v 2200mAh KongPower packs. The RPM with no load / volt: 4600 1/min, so it could've been spinning at 45 to 50K rpms loaded.

i thought the plett extreme and shadow are both 4 poles and the indoor was 6 poles.

I cant find any info on that though so correct me if i am wrong.

The Extreme is 6 poles. I have it open to change the bearing.

Regardless, 6 poles, 4 poles, it is not going to change the power output, which is all that matters.
