Like aaron said, the ones out of TR magna's are Nippon Denso thin pancake motors with an iron free armature - Great power from not too much weight, but not something you'd want to be mounting to directly. _________________ Jeff Ferrara

My dad bought the fan motor today. It's bigger than I expected, so I might have to go for friction drive or get two miter gears and connect the bottom one to a pulley and belt. Then at the other end is the disc, which is secured by sandwiching it between two pulleys. _________________ It seemed like a good idea on paper...

I've just mounted the second drive motor. I had trouble with the gearbox as I set the slits for the hose clamps too far apart and had to get them sawed some more. After that I still had some trouble but managed to tighten the hose clamp. _________________ It seemed like a good idea on paper...

Does anyone know what type of fan motor this is? It has the same mounting flanges as the Nichi-ra, but it seems to be longer than the nichi-ra. Here's a pic: http://www.robowars.org/forum/album_pic.php?pic_id=591[/img] _________________ It seemed like a good idea on paper...
Thats off of a old skyline/pintara,I think thats what most people use as saw motors and I think thats the same one angus is going to use on his new bot. belt driving a big vetrical disk

There's actualy two versions. The one you have is what glen used in kang, and is the fattest of the two and has the tabs equaly spaced at 120 degrees. The other is slightly thinner, and two tabs are slightly closer together than the other. _________________ ( •_•)

Friday-Monday there wasn't anything to do as me, my brother and my parents were going to Hamilton Island. On Tuesday, I found that if for my frame I used three bars stacked, the unpowered wheels will be to high, if I put the bar with the wheel in it at the bottom, it would be too low. So now I'm mounting the wheeled bar on top of four aluminum plates (two at each end). Then another bar goes on top of that and either another bar 3mm smaller than last time or enough aluminum strips to reach the height I need. _________________ It seemed like a good idea on paper...

I've almost completed one side of it. I've bolted the first two bars, the wheel and the aluminum to the baseplate. I need two bars 6mm shorter (Not 3mm, reffering to my last post) than my current bars, one for each side. I could get aluminum ones from Carpal Aluminum, steel bars if I can find the right chair/table/bedframe/other thing with steel bars as a frame, or if CA sell steel (one of their ads had something about steel roofs), then I can get steel from there, too. _________________ It seemed like a good idea on paper...

Sorry, the picture is too large and/or corrupted, so I couldn't load it.
Anyway, I just mounted the four bars and wheels on. I'll need to trim the ends of the bolts once I have the last bars and the upper armor because if the robot is flipped, it'll land on the screws. I saw the powered wheels were too high, so I removed the aluminum plates under the motors. The pictures will come soon. _________________ It seemed like a good idea on paper...

I saw that the robot topples over when I put the fan motor on, so I tried a castor I had, but it lifted the front of the robot up, then I put the castor up higher, it still didn't work! It had to be lifted up pretty high to work, so today I got some wood blocks mounted to the front of the weapon mount on each side. Now the robot is fully supported even with the fan motor.
My pictures STILL don't work, even though they were shot with the SAME camera as the pics that did work! _________________ It seemed like a good idea on paper...

I don't quiteunderstand what you mean, you really need a photo of it, try again. How could the motor roll the robot over? _________________ ( •_•)
the size of the picture is the problem if you are uploading it here, it must be under 800x600 pixels and under a certain size
IE make sure its a jpeg (jpg) _________________ Mechanical engineers build weapons, civil engineers build targets
