i am considering using one of the old 3" dia CIM motors for a budget electric scooter project but i can’t find any specs on them.
i’m looking for info such as k/v, torque, amp draw, rpm, ect
does anyone have experience running them at higher voltages like around 24-36v? if so, how long do they last at higher voltages and is it a good idea to run them that high?
and finally, HOW DO YOU MOUNT THEM???
seriously, i don’t get it. there’s the one mounting hole on the front and that’s it.
If you aren’t seeing the other mounting option, odds are someone on the team you got it from has cut it off already. (The motors are supposed to have a stud on the face plate, to which a belt tensioner attaches. You could remove the tensioner and retain the stud.) Clamping is a pretty good option, though unfortunately, I don’t think these motors had an alignment boss around the shaft.
As I recall, the front face was somewhat teardrop-shaped, giving two flat sides that could be used to keep it from rotating. I know 330 clamped theirs by bending allthread into a U shape of the proper diameter and setting them on a light-duty platform, then using the custom Ubolts through it, back in 2006, and as far as I know, it’s still there. (Admittedly, this was a shooter motor–but we never did have any issues with the shooter not working once we got it working.)
I used these motors on a project a few years ago. The way that I mounted them was there are 2 bolts that hold the motor together one when stock will stick out ~1.5" you can replace the 2nd one with a longer one so that you have 2 bolts to mount from. The thread is an M6 but I dont recall what the pitch is but I can look it up if needed. I also cut the profile of the face of the motor into the plate that it mounted to. Below is a link to some pictures showing what the profile was. I can send you the CAD model of the plate if you would like.
