New 1/5 Motor, BigBlock "pics inside"
 

Picked up a Kollmorgen 400 brushless motor for my 1/5 yesterday. Its absolutely monsterous compared to the CIM robotics brushed motor and hopefully will displace even more raw power. Its so wide that I will have to make a custom plate that will have to hang off the chassis to be able to mount the other side of the motor.

Here are a few pics. "Internal pics will be posted up asap"

Holy Moses, that is big...looks like w/wings it could fly w/that power plant!

Balance issues? Or are you gonna have some type of wheeled outrigger? :smile:

Ill just deal with the balance issues.:lol:

Now for internal pics... Has 18poles and the rotor size is 73mm x 46mm.

What are you looking to get for top speed....just curious.. Also out of curiosity, what are the specs. of the motor.

The motor is 115mm wide and 79mm long. The kv rating is around 130kv.

Top speed Im hoping to get around 30ish miles per hour. Im looking for torque mainly.

That should be enough torque to put the truck on it's lid w/out much trouble....:mdr:

Extend the shaft out the back and make it direct drive somehow. :smile:

What esc are you gonna use, 18 poles thats something every esc cant do...
And yeah, some specs for motor?
e. i was too slow

wow, what kind of wires are you gonna use, like 4 gauge?!?!?! put that thing in a pede... :lol:

I have some 000 guage power wire if you want it. :lol:

That is a much easier motor to rewind. Try and do what Brian said and make it direct drive. There are also tons of good BL motors out there that are a bit smaller. I have a few here and all I need to do is rewind them to handle the current and rasi the Kv a little.

:gasp: :surprised: :gasp: :surprised: :gasp: :surprised: :gasp: :surprised:

















All I have to say is wow, that thing is huge! I agree with the other guys though, direct drive with something that size would probably be perfect, and would make it alot more balanced. Looks great! And I want a video of that thing powering the truck around ASAP!!!

Bet he doesnt hear that alot...:lol:


+1 for direct drive.


how much current is that beast gonna draw?

Funny if the joke's on him....

Not funny if the joke's on me....

Oh of course we have to get the immature jokes in on me:whip::lol:...

I dont think Im going to be able to do direct drive. The rotor is on the neo mag like a chimp is a on bananas.

Holy... How much was the motor? What ESC/batts are you planning? :neutral: :neutral:

Motor was $60 from my bro. I plan to use the BP 200a 10s esc and two 5s flightmax 5000mah 25c packs in series.

:surprised: WOW! That is ginormous! Can I have two? I... um... have a bike... LOL

And I thought the CIM was the largest motor I ever saw.(thanks FIRST)

I think you're mistaken. I've seen reviews of the Supersimple/BP 200a esc saying that they should never be run over 6s. Consider a Sentilon 100a HV ESC.

I second that. Are you using mechanical brakes? You'll have to with the Sentilon.

you sir need to get out more:lol:

FIRST sends an email to companies who have overstock of stuff people dont want...and are willing to donate...and they stick it in the kit

been trying to get the GDC to allow brushless as a add on...but the "less fortunate" team would have a disadvantage. Im all for fairness...but C'MON:whistle:

speechless... like whoah... thats huge... that what she... - umm said

's what i was thikning.. and it just happens to be that the Neu 22xx series uses the same mounting holes and shaft diameter as the cim....:whistle:

Y'all haven't seen Neu's 40XX series hav you? Maybe it was 44XX but there was a blurb on Neu's website about it. Nothing on Castle's site though.

They would never use these motors. And would probably never use sensorless brushless for 100lb robots seeing that cogging would casuse a major issue.:whistle:

Not mistaken... :whistle::lol:

Good to see the ESC I was having made is showing up again in here. Too bad the company that was going to make it sucks in every thing related to cars. They sent me 2 30A car ESC that has to be the worst even I've seen. There will be better ESCs coming out soon.

Here is the thread: http://www.rc-monster.com/forum/showthread.php?t=7651

Edit: That picture there was taken after I sent them 800 MOSFETs and waited a long time until I decided to just sell the MOSFETs and made a nice little profit on them lol, I paid $0.45 each and sold them for $1.20 each, I might have paid less, but it was a while ago.

question,
it says dynamic breaking, is that just marketing or does that esc work for cars, without mechanical breaks? or is it just like any other flight-esc? does that mean kinda "proportional"-break?

I use a cheapo-chinese-200a esc, wich looks quite the same. except the automatic breaks at neutral position it works just great. I have added 4 more power caps (680uF each), and 2 fans (one on each side...). looks ugly, but is rock solid. excellent acceleration etc. it was planned to be the "spare"-esc, cos the etti burned quickly, the scorpion smoked during setup (I get replacement)... but is now in permanent use.

It is for prop folding basically. The brake is not proportional like the car ESC.

Oh, I thought you were talking about one from the SuperSimple line. How much does that controller in the pic go for?

manufacturer
 

btw, regarding your esc-plans, did you ever contact "etti" as a manufacturer? I've been in contact with a guy in HK, as they have replaced one esc for me (suddenly no more beeps at all). I ordered the esc in UK, so I guess this guy was from the manufacturer. whithin 10 days I had a new one (which burned due to faar too long gearing... buhuu...).
I just wonder, because the quality of the ettis is quite ok, and the folks have been very cooperative. nevertheless, the breaks don't work for cars really (boat-esc).
the manufacturer of the bp-200a is suppo model, I've just asked them what "dynamic" means. I'm curious.

Around $80 or so from I hear.

Holy cow, that motor is quite the brick.
Reminds me of the pancake motors people started using in battlebots...like these ones in vladiator(man that thing was crazy fast for how heavy it was):
Vladiator.

LEM 170 Electric Motor.
Not cheap!

Post vids of that thing when you get it goin'. :)

Wow, battlebots use to be my favorite show ever. Until they went off the air...
