Fly wheel help

  1. last week

    Hello, my friend and I are trying to build a very high power vertical fly wheel, for fun. We currently have the gear train set up for 1:96. We power the train with 3 v5 motors(standard) and we get just 100rpm with them without or fly wheel attached and I have removed most friction. I'm just wondering is 100 rpm the best we can get from the motors? Do we need more motors?

    If you make it to worlds, think there is a chance that you can hit the flag at NGF field from NASA field. Lol

    I am no expert, but from my personal opinion, I would add alteast one more motor, and make sure you have a ratchet to let the flywheel spin somewhat without contacting the motors after the motors are shut off. I would hate to see a perfectly good batch of V5 motors smited from the strain of a flywheel made simply for fun.

    And most importantly, if the result is good, im sure I speak for all of the vex forum when I say that we would very much like to see a video of the result.

    Thank you

    Thank you

    My team currently has a 15:1 flywheel on 200 RPM V5 motors. We've been working on it for a fair amount of time and surprisingly enough there has not been any problems with the internal gears (yet). Sometimes it feels like the motors themselves have a way to coast/deaccelerate rather than stopping immediately.

    Back on OP's question:

    @Newbie24 I'm just wondering is 100 rpm the best we can get from the motors? Do we need more motors?

    They should be able to spin faster than that at max power. Try and look for other sources of friction (i.e. gears on metal contact, more than two bearings on a drive shaft).

    @Gameoa I will have a ratchet on the fly wheel once I hook the gear train to it, for now I'm running it without the actual wheel attached to it. I have looked for any metal on metal contact and I've made sure there are washers on them to reduce friction. I will be adding that fourth motor. Thank you for your input.

    I will try to add a few more bearings around the longer shafts. Thank you for the suggestions and help

    If you have the motors, you might as well just stack up a bunch of them. You can get more power to turn a higher gear ratio.

    Hopefully that bang isn't your robot exploding, as cool as that would be.

    And it’s the answer.

    If we’re trying to build a super-flywheel, then why not use a bunch of brains so that we can add even more motors from more battery sources. You could snipe someone from the stands at finals at that level.
