Insides of a Plett heli motor
 

Plettenberg HP300/20/A4

Just picked this up, and I figured I would post a few pics of it for all of you to eyeball. Very interesting motor, lots o poles, and a built in fan (run Brian G!). Has an almost completely hollow rotor core, looks to be made up of 3 disks, 1 for each end and 1 for support in the center, kinda like a drum/barrel. Those 3 disks have holes drilled in them to further lighten them. The can is also very lightweight. Construction quality seems very good, as has been the case with all of the plett motors I have owned.

740kv, and it has a 5mm shaft and std 540 bolt spacing for 3mm screws. I plan to run it in a buggy on 10s lipo. Not sure about the power, but should be comparable to a 1907 neu, so around 900-1000watts potential. So also comparable to a 1509-1512. Given the light rotor and multipole it should spin up fast and have lots of torque!

i just pray you and metalman keep the handporn coming. yes, thats a pun....

Motor Porn!

That kevlar wrapping looks really clean.

I've actually shaken that hand... That sounded dirty, shaken that hand. Everyone loves handporn too!

Btw, linc, don't you have enough spare in that drawer that have yet to be touched? You'll need to expand to a second drawer next...

Hand porn, motor porn? I will show you guy motor porn, let me snap apic of the motor drawer than NS is referring to...

NS, yeah I have a few spare motors laying around... I have some lower kv mega 6 pole motors that I need to put to work. Just waiting on suitable sized hv escs to surface.

yeah, hv would be nice. my 1050/kv 1521 wants like 12s.......

and lets not take a peek in James' drawers..........

You're right, it would scare people....

And make women drool...

Now you're imagining things....

mouth breathers, droolers..... its all pink on the inside, eh Linc?:lol:

oooh i'm feeling frisky today:yes:

I know the women are imagining something...

Yes you are... and I am still laughing on the mouth breather comment, some nasal decongestant may help that out...

:lol:

Back on topic: Motor looks quite interesting, but it looks like a rock could get caught in the fan, between the case causing the motor to seize possibly frying the motor/esc. I'm skeptical of the design, but if it works, looks like it could become a very good design.
Back off of topic: Hand porn is a very eery topic, one minute you're talking about motors, the next minute everyone is giving everyone high-fives!

(There's a joke in there I think is very funny, first one to find it gets a prize!)

Good point, Ian. Maybe use as a crawler would be all right, but I'd be worried about debris otherwise.


As far as the joke- I get it. "High five" But you're young and still growing. You'll see 6, maybe even 7!:lol:

The plett is a high-pole motor though. Wouldn't cogging be an issue since it's non-sensored?

[joke] But I thought it was brought to me by the letter 4! [/joke]
