Uwe Report post Posted February 29, 2016 I stumbled across this ebay listing of a Adler 30-70 with a wicked chain drive and geared motor setup and wanted to share some pictures to preserve them in the LW archives. If the needle won't penetrate the material, it certainly won't be because of a weak motor or slipping belt! The price seems rather optimistic. Quote Share this post Link to post Share on other sites
gottaknow Report post Posted February 29, 2016 I have a few of those motors kicking around the factory. The one I use drives the 7' long blades in my down blowing box for filling down jackets. The shaft is 8' long, 1 3/4" in diameter. The torque even the little ones generate is amazing. I've got another smaller one that drives a conveyor belt on a Swiss made fuse press. Cool find Uwe.

TinkerTailor Report post Posted February 29, 2016 (edited) That is pretty cool, thanks Uwe. By the name plate, It appears to be a 1/25hp motor on a 32:1 ratio reduction. It says the output rpm is 100, so that would make the motor rpm 3200. At the 1.3 amps listed draw and 120 volts, that is only 156 watts......pretty small motor spinning fast. With the 1:1 chain drive, max speed would be 1.6 stitches a second. In order to double the speed you need to half the reducer gear, to 16:1 which would overtax that motor on this machine. It is a robust setup as is, but with the small high rpm motor at a high gear multiplication, Fast speed probably isn't an option. Not a huge deal on a patcher.
