We also had to go with a 25:1 on a cim motor to be able to lift totes 4 totes fast enough with enough power.
Oh right, when I was in 115, we started out with one 775 and I believe a 1:100 reduction, and that was barely able to lift up 6 stacks. Although I calculated my scenario to do the job in 3 seconds (the main bot stacks much faster).

As for voltage... I never considered that actually . If it's a 10 gauge wire it's going to be bulky... and that means more weight. I guess I can remove the can burglars if I'm going to add this with the main bot.
