wheres the friction coming from

ok heres the story, i bought some nice new neo's went to put the in the stage one motor (just wanted to see what it could do with all that torque) i desoldered the caps from the body, and made a paperclip shaped like a U to move the coms outa the way, bent the tabs back and pulled the enbell off

i then used a paperclip with a little bend in it stuck inside the hole at the front of the motor to push the magnets out.

i then put my nice new neos in and made sure to reintal the retaining clip, i then put the endbell back on resoldered the caps

when i gave the motor a spin it felt "notchy" i thought this was weird, but decided to try it anyways

i put it into my xmod and ran it, it accelerated like crazy but only went a quarter as fast as it did with the stock motor, i knew it would go slower but this didn't seem right...

so i proceded to try and determine what the problem was, pulled the motor apart again and re assembled it, made it a little better but still not even close to stock speed...

i decided to try it in a stage 2 motor, i put it all together and ran it, now it had the top speed of a stage 1 motor but the stage 1 motor put it to shame on the acceleration side of things.

when i decided to put the stage 1 motor back to stock, it didn't spin right, it felt like there was more friction then it used to, i compared it to my brothers stage 1 motor, it definatley didn't spin right, i decided to break th motor down and figure out what was causing the friction

i basically narrowed it down to the case, no magnets, no coms and the thing just won't spin right

so my question is why? what did i do wrong so i don't do it again and can i be fixed?

sorry for the long post...

Try Lubing the motor, I had a problem awhile ago here the motor was screeching. I used some Slot-Car gear lube around the Endbell and it works perfect now. This was a Completely stock mini-z motor tho.

Re: wheres the friction coming from

well i'm gonna try swapping shafts as soon as my pinion puller shows up...
thanks for the input!

Re: wheres the friction coming from

If its the can that's warped, try the shaft in a different can, and if the problem still persists, then its the shaft alignment, like mongo said. If all else fails, then discreetly swap your motor with your brother's and put neos in them . He wouldn't know. :lol: :roll:

Re: wheres the friction coming from

Neo's will make the motor turn not as easy as weaker magnets, but since you took them out and you still have friction its not the mags.

I believe its shaft alignment also. If you did not somehow torque the front bushing, its probably the way the endbell is seating.

XD ya did nothing wrong man. Neos are very strong magnets. Basically they greatly boost up your torque and rob some from your top end. Use that combination and just swap in larger gears.

Re: wheres the friction coming from

How's the bushing in the can seated? If you have friction, you may have misaligned the front bushing compared to the rear endbell bushing, causing friction on the armature shaft.

Just a thought. :wink:
