Hi All,

Please let me know, if you know which DC Motor can lift one pound of handle. The DC Motor is 9VDC and running about 20 Second, then stop. Please let me know, whcih Motor and mechanical connection how to lift up the handle? Thanks, in advance for your idea and sugguestion.

Apply the law of conservation of energy. Assume say 50% overall efficiency, including the gearing.

 

Thanks, Do you have any information such as diagram?

Torque rating at 9V under full load? Length of lever arm?

This is all Physics 101

 

Yes, 9VDC full load but it need run only 10 sec and stop. I need mechanical connection to move the arm door. I need to lift the arm door up for 10 sec. I think the arm door wieght about one pound.

 

What motor to use to lift 1 lb, 3 in, in 20 sec @ 9 V DC? Ans: G 16034, The Electronic Goldmine. Add .76 in dia drum to shaft, add cord & limit switch. Impure speculation, not knowing where you are, & limited information.

 

That motor look good to me. I will order it.

Thanks,
Kevin
