band saw speed for metal?

i get 125-215 sfm for 1008 steel. by the time you get down to 16 gauge, you are probably better off with a shear or abrasive wheel. too thin is hard on bandsaw blades

AC vs DC wont affect the torque. that is mostly a function of motor design. Tesla uses 3 phase SCIMs which are 3 phase AC, not DC. Universal motors like a treadmill are series wound brushed DC motors with some design changes to work better on AC.
