Hello, I’ve almost finished my lift, it’s an eight bar, but I had the intention to put one axle with two motors per arm, one on each side of its. But, somebody told me that it’s better put two axles with one motor for each one. Which option do you think it’s better?
We’ve had a better experience (with a 1:7 ratio), with putting a motor above and below the 84 tooth gear with their own axles and 12 tooth gears. This also makes it so that you don’t need to have an exact axle length to fit into both motors, as accessibility is key.
But, in both options, the motors would make the same strenght to elevate the arms?
I’ve heard that it’s “impossible” for a small shaft to overly twist (aka turn into a “drill bit”) when it is directly driven by a single motor. But two motors might be able to “drill bit” a single shaft when directly driven. So that’s probably why somebody suggested to you to drive each small shaft with only a single motor.
