Default capacitors on motors

Hi
I got an orion chrome stock with my car, and I wouldnt mind getting it going, it doesnt have any capacitors on it though. Can anyone tell me can they be soldered to the endbell or do they have to be soldered to the can itself, which would be a pain cos you would have to unsolder them every rebuild...

The motor has two sets of tabs on it one would be for the ESC wires (not sure which it would be though) i guess the other set of tabs would take the caps and schottky diode?

Any help would be appreciated

are you sure it doesn't have caps?? almost all motors come with them pre-installed these days (but not all use the same circuit board style as monster stocks etc)

have a look around the endbell screws, the caps are often hidden away, recessed into the plastic part of the endbell

If they are there they are very well hidden I think maybe the previous owner may have removed them. it has a red and a black heatsink looking things on it that are held in with a screw and that is all

No, they're there, but they're not the kind you're most likely used to seeing. Like Trinity's motors today, they use surface-mount caps in them, wedged in little places between parts of the brush hoods, & they don't look like regular caps, they look like little chips of material(maybe 1.5-2mm long, these things are TINY). As long as no one has disassembled the brush hoods & lost them, they should still be in there...

as grizzbob said they are mounted underneath the brush hood.
but if you want to put some on you will have to have to motor capacitors 1 is soldered to each tab then both soldered to the middle tab were the ring mount is.this would then earth it to the can.

azenis, i think you may have misunderstood me... when i said endbell screws i didn't mean the ones holding the brush hoods on to, i meant the ones going through the whole endbell and into the timing ring, holding the endbell and can together.

as grizzbob said, they don't look anything like the caps you're probably used to seeing. probably a little white 'chip' type thing. they would only be on one side of the motor, so if there are little slots next to one of those screws i mentioned, look into those little slots. if you can see anything whitish, that's a cap. if it looks pure black, the previous owner has somehow managed to pull it out as you suggested.

hope that didn't confuse you too much lol... i'd take a photo of what i mean but i don't have any motors with that kind of cap in them, or a digi camera to take photos with
