Re: DC Motor and Gearing

Edit: Yes, gear ratios multiply.

Let's say you have a 1 to 4 reducer - 1000 RPM gets reduced to 250 RPM, right? Now, the second reducer is also 1:4, so 250 RPM gets reduced to 62.5

1000 / 62.5 = 16, so two stages of 1:4 is the same as 1:16

In this case, for 1:8 you'd want 1:4 and 1:2
