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...

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.

[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.

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.

[lutach]

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.

[zeropointbug]

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?
