Team 708 Drivetrain

[tsj25]

I think Thomas was missing the meeting we calculated the efficiency. We used a clamp style ammeter and checked the current through the battery cables at full speed with the robot up on blocks. It worked out to right around 2.8 amps per cim and we compared that to the listed 2.7 amps of a cim at free speed. We were all surprised by the results but the improvements were noticeable. We ran the same 6:1 reduction last season with the am14u 3 cim gearbox and the new drive was noticeably quicker.
We have a meeting tonight so I will have Tom take a pic of the cim gears and get a more accurate weight. But the weight savings going from steel to Al gears would be around 5 lbs total.
And Griffin, you know our shop is open if you need to use any of our machines or want a closer look at the drive.
