Motor for a forklift

We are going with a forklift design and with the absence of the minibike motor we are looking for an alternate to raise/lower our forklift. Would using both fp motors create enough torque to lift a 6lb structure plus the 10lb ball at a reasonable speed? Or would the globe motors be a better alternative?

Yes. As long as you use a gear box. We actually just used our 2007 lift to lift the ball and it is driven by just 1 FP motor using an AM Planetary and a 56mm BaneBots Planetary. It was fast, but it was moving at a snails speed either.

Re: Motor for a forklift

we're probably using the a FP also, and for the same idea... probably...

Re: Motor for a forklift

FP motors with the gearboxes are more powerful than globe motors. so yes, i would advise using FP's.

Teams 968 and 254 used 2 FPs and a rotating drum last year for their lift bots.

Our 2004 robot had 2 FPs on one drum and winched itself up on a bar--that's 120 pounds + battery, all on two FPs through the gearboxes and the frame through screws in the mounts. Two FPs might even be overkill, but you might want that.

Re: Motor for a forklift

Remember that the van door motor is back in the kit. (I haven't checked to see if it's the same as previous years as far as performance but I would assume it's similar). In 2k1 we used a van door motor tied to a drum. The Van door motor can be direct driven as is because it has a worm gear box built into the casing.

FYI: If you didn't know, 2k1 had similar size/weight balls.

On second thought, it would probably be faster using the FPs, but just throwing more ideas out there.

Re: Motor for a forklift

We used the keyang motors last year to work our arm. Those things are super torquey and don't backdrive.
