I just got some information from "Deep Throat" about a new Plettenberg F3A motor in development, apparently a direct drive in-runner... Interesting concept. Should be available later this year.

I'm not so sure I'm crazy about the four prop bolts, however.

Well in theory you get the best of both worlds, higher efficiency with no maintenance. But with outrunners now days so efficient it doesn't make sense, except in the lab. What is more important today is being different (and not easy copied by the others) therefore it is easier to explain the premium price Plettenberg needs to ask for because of Made in Germany. Don't ask me how I know , but I worked long for a premium car manufacturer!

Perhaps, but it's interesting that this is a direct drive inrunner vs. a geared motor as it is the gears that require the most maintenance. This looks and sounds like the ORK (Out Runner Killer) 17 and 19 series from Neu.

My simple understanding is:

brushless outrunner = The magnets rotate outside the windings, which are stationary.

Brushless inrunner = the magnets rotate inside the windings, which are stationary.




So the outrunner spins more mass at a greater distance from center than the inrunner which would explain the faster spin potential for the inrunner.


But, this type of motor looks like the windings and the magnets rotate so I have no idea what kind of animal it is, and I guess I'll have to wait for some of the experts to chime in.

That is possible, but not really applicable in this case.
It matters in a geared set-up, where you (may) want the motor to spin at a very high rpm, but in a direct drive application for F3A you still only want about 6000 rpm, which is no problem in either case, inrunner or outrunner.

Cooling is better for an inrunner, though.

The new Pletti will be named Advance 30/10 and it will have 91% efficiency. To compare, the efficiency of the evo 30/10 is 86% and the soon to be released evo 30/9 two has an efficiency of 88%.

Perhaps something is lost in translation?

It will be very interesting to see how this inrunner goes with direct drive. You have to wonder if it will have enough torque...

Cheers
Jason.

Of course there was an X rated movie that came out around that time... I'm sure that one does not have to do with the other

Interested in the motor, unfortunately that picture doesn't tell me anything about it! Which is why it was released I'm sure..

There was also that Bill Clinton and Monica Lowinski scandal too. Now that was real "Deep Throat" Classic!

Back to the motor.... Yes, the pics are obviously to get people wondering.. The new Hacker Q80 also looks interesting. The Q80 is due for release next month.

Cheers
Jason.

Its a big diameter inrunner.

That will help with torque.... Do you know how much it will weigh Chad?

The Advance 30/10 is being tested presently, and compared to the evo 30/9 two the pilot has 15% more power. The Advance 30/10 weighs 550grams, and since the power levels are so high they are now thinking about designing a smaller version of the Advance that should weigh below 500 grams. Interesting stuff.

Status: offline 		Hi Morten, is there any info on the availability of a vectorthrust solution for the advance as available for the 30/10 now. Yesterday started testing with the vectorthrust. It seems to have a lot of potential.

This EVO 30/9 is this just a higher Kv version of the 30/10 or a very different design?

Has anyone yet tested the similar Neu direct-drive inrunners?

Status: offline 		Hi Hans,

Yes, they plan to do Vector Thrust for the Advance series as well.

The Xtra 30-9 EVO II is an optimised version of the Xtra 30-10 EVO with lower internal resistance and higher efficiency. According to the data I have seen the KV is identical to the 30-10 EVO, so you can use the same prop types.


I don't know what the price will be for the Advance, but it should be available in 3 months.

Status: offline 		Translation of Advance 30-10 text:

Standing still is going backwards therefore we constantly work on moving forwards. The result is in this case taken literally: Advance – Moving forwards!

While other motor manufacturers are busy copying our proven technology this motor for F3A aerobatic airplanes goes a completely different way. The revolutionary construction combines the advantages of the out-runner and the in-runner. The main advantage comes from the laminated rotor that optimises the operation at partial load.

Due to the reversal of the - for out-runners - typical SPS winding system these advantages have also been integrated into this propulsion system. An internal fan wheel optimises the cooling of the rotor and the winding. The efficiency could be raised considerably compared to normal F3A motors and is at 91%! All this at a weight of 565 grams. A stable 12mm hollow shaft ensures outstanding stiffness. The in-runner is easy to install in the fuselage. A technical stroke of genius: Advance – always a step in front.

Status: offline 		Translation of Xtra 30-9 Evo II text:

The Xtra 30-9 Evo II is developed on the basis of the Xtra 30-10 Evo - the leading electric motor in F3A. The motor is modified in accordance with the newest knowledge in the area and hence brought up to date.

This means that the magnetic system has been optimised further and the number of winding turns has been reduced. This has the effect of reducing the internal resistance while increasing the efficiency and at the same time the performance has been increased.

The running speed of the new motor has not changed compared to its predecessor, meaning that the same prop sizes can be used.

The motor is designed for aerobatic models up to 6 kilograms and 10S Lipo's or scale models up to 8 kilograms. The idle speed is 225 rpm/V, and the maximum prop size is 22”.
