Plettenberg vs. Neu?

[jordan...]

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

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...

[zeropointbug]

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.

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.

[zeropointbug]

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

How much does it weight?

How long is the rotor on it?

[suicideneil]

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.

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.

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.

Plettenbergs quality is second to none and are easily the same quality as Neu's or Lehners if not even a little better , I have all three in a variety of sizes . The pletts are enormously powerful and have huge torque for there size . the big maximum is based on the plett 220 frame, Neu's on the other hand are probably the most efficient out of the three............

hi

yes the quality of the plettenberg is above reproach. we run severeal of those motors here only in very dirty offroad applications. i have one here that is used all-season since autumn 2003 with zero issues. still no play on the bearings or anything. it runs like on the first day. they are designed for offroad applications and need no modifications for that like others do.

so i'm still considering either a BM or a 1515/1y. Which would be a better choice if i was to run on 6s??

I know that the BM's max rpm is upto 70,000, whereas the Neu's is only 60,000. Would that play much of a part?

thanks

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.
