Thread: Help with HUGE Motor

Tweet

I found a huge chain driven motorized platform the other day and need a bit of help with it. It was ment to be used as a rotating shoe display. I took the motor out and have plans for it but I'm unsure just how much weight I can safely put on it. I would hate to build a prop and burn out the motor on its first go around.

I took these pics of the motor's specs and would like to know if any body can tell how much tourque it can take or how much weight its designed to hold.

Any help would be appreciated, Thanks, Marc V.

You have a lot of torque there. Just looking at the chain/jackshaft assembly it looks like it's made to handle some heavy loads.
One inch lbs. = 0.083333 ft. lbs. So, your motor is rated at 500 in/lb; that converts to ~41.65 ft/lbs. You'll need a beefy power source - the motor requires 6.5A according to the label. Computer power supplies come to mind.

Does that mean I can put approx 41 lbs of torture wheel (oops I gave it away) on this and be ok?

Will the wheel be mounted vertically? The load won't equal the full weight of the wheel. If the wheel is heavy, use a good bearing on the axle. This motor should handle that and then some, but may need an assist when starting up as the HP is just 1/15th.

yes its like Otaku said. the weight of what your moving isn't the issue, its the amount of friction or resistance in your prop that's the problem. I could build a wheel as big as my house and that thing would run it once it started up!
