A family of Polulu Metal Gear Motors have speed reduction gear trains that range from 1:1 to 400:1 Part 1: Use the following gear train to solve for the overall gear ratio (output speed/input speed) The set of gears within the diagram include the following teeth numbers: 12, 10, 10, 22, 22, 24. The stars indicate the meshing locations within the diagram. 12 Input 22 10 22 10 24 Output Part 2: Using the diagram above, the two middle gears are compound gears where the inner gear and outer gears are rigidly attached and rotate at the same angular velocity. Using a catalog for Polulu motors what is the product number of the low-power motor that corresponds to the gear train?
