Need some help collecting motor data

[longballlumber]

Hello all,

I am reposting this request outside of the IMPBA "Spec or P-Limited" motor discussion. I am hoping by putting this in it's own thread more people will see my request and offer to help.

I would like to collect some weight data associated to the 37X62 motor limits. Anyone willing to weigh the motors they have (minus cooling jacket and collet) would be appreciated. The following is what I would be looking for;

Manufacturer
Model and KV
Measured Length
Measured Diameter (Not a priority)
Actual Measured Weight noting if the value includes connectors or not

The more data points the better even if it’s the exact same motor multiple times.

Thanks
Mike

All motors? Darin has a pretty good list somewhere. If I sell it, I can help fill in the blanks. Let me know?

Hi Steven,

The only component that Darin didn't have in his data was the actual weight of the motor. I would use the information published by the manufacturers, but we have already seen instances where can length isn't consistent. I can only assume there will be variations of the weight between different winds and the variations in length.

With that being said I would appreciate any data you can provide as stated above. The primary items will be actual weight minus cooling jacket noting if the value includes connectors or not, and an actual measured length.

Thanks
Mike

Mike..

Bone stock AQ 2030..206g.

[Doby]

Mike...

1)Bone stock TP 1950....261g..can length 59mm
2)Bone stock TP 1950....259g...can length 59mm

These were the ones Peterson was offering up a few years ago.

If you could get me the can length on each one of these that would be helpful. The TP's seemed to change that several times. Thanks for your help!

aqua7001 2030kv 56.4mm 209.4gr with 4mm connectors
tp 3630 1950kv 57.6mm 267.7gr with NO connectors
leopard 3660 x2 60.2mm 262.6gr with 6mm connectors


if you want any other weights of something Im selling let me know?

Just a note, the tp3630 will not be the same from each reseller. Customers have requested them in the shorter cases over the last 2 years, so we have ordered them that way.

Here's a cleaner list of what I've actually had in my hands and personally measured.

And for those reviewing these numbers and specifically the "Spec Neu 1415" compared to the "Mod Neu 1415"...
I have NO IDEA why after reducing the can and shaft length by 8.6mm, the weight is almost exactly the same.

Hi Steve, thanks for that data
I'll step in here and help Mike out.

These additional motors would be good the have actual measurements on:
Leopard 3660 X2 2380kv
SSS 3660 1620kv
OSE Raider 3660 in all 3 winds (1700, 1850 and 2030kv)
TP 3630 in the 1500kv and 2220kv winds
Neu 1415 1Y 2200kv
TP 3640 4Y 1935kv

Stuck the thread Mike. Thanks for taking this on, and thanks for the help fellas!

Harder to find data will be on the Lehner 1930 and 1940. It'd be really helpful if someone with either/both of these motors could provide some actual measurements and weights.

Spec weight of a 1930 is 230g. Don't know if that's with or without the fan. Size wise it would fit within a 37mm x 62mm limit with or without the fan. And based on the spec weight it looks like a max weight limit of 270g area would still allow this motor to qualify. Which I think is fine.

Spec weight of a 1940 is 290g. This motor measures 64mm long without a fan so it seems it MAY be possible to cut down to 62mm. However, with a weight limit of 270g area, it APPEARS this would remove the possible cut down 1940 from being a legal motor. Which I think is another step in the right direction.

Sorry Mike, I update post #5 with the lengths.

Morning guys,

Keep the information coming. The more motors the better; even if it's the same model.

Mike,
On Saturday...Besides all the Neu motors I will also bring two Dynamite 1500s. I need change out the connectors on them so I will burn off the stock ones and bring those bare so you can get some good weights on them. Actually, same thing with the one Dynamite 2000 I have. I'll bring that bare as well.

Actually Dave, along with the bare motors bring the loose can coolers also. If we weigh those independently we may be able to keep a "cheat sheet" handy showing the predetermined weight allowance for "X brand of Water Jacket". Then some quick math will help determine if motor is over the limit. I can tell you an Aquacraft gold cooling jacket is around 33grams from memory. I would suspect the HRC jackets will be the heaviest.

We can do the same thing with Connectors.
