What a Model Number Tells You?
-
We follow some rules to create each model number. A model number would tell you a lot of useful messages. Here is a sample.
-
 -
-
So here we can learn that it is a 37mm Round Spur gear motor, 12V driving motor #555, no load input speed 6000rpm and reduction ratio 100:1. Hey, what about output speed? You need to do a little calculation. Input speed 6000rpm ÷reduction ratio 100 = 60rpm.
