Re: What motors are you using for your lift?

One CIM on an 8.45:1 gearbox (same as on the KOP for interchangeability), geared down 32:15 by chain, then lifting using two #35 chains on 15 tooth sprockets. It has several times the lifting power we'll need, because we're going to try it without a brake. We're only using three CIMs for drive, so we are going to check the current draw when we hold the maximum load (4 totes) and add another CIM if it's much over 20A, or if we experience too much heating during practice. On the curves it looks like it'll be about 14A, which means about 170W, all going to heat when holding station on four totes. I really suspect that we are going to build a brake on Thursday and Saturday.
