The motor power draw required to turn a mill from rest to the operating speed includes the energy required for the initial starting torque and mechanical arrangements to rotate the mill. It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill Diameter ) n

Cut laminated pine panel to size. I went with 23”x31”. This is really the structure of the mill stand. You need something pretty stiff and strong to hold the weight of the mill/motor/gear reducer and give the mill base some rigidity. I wouldn’t go with anything thinner or wimpier than laminated pine.

Yes you are right, that is why the motor is supposed to be a 310V or 340V DC motor if the input AC is 220V or 240V. For 110V AC inputs the motor is supposed to be rated at 155 V. Alternatively you can use a 240V to 150V transformer and then rectify the transformer output for the getting the matching DC for the motor

Work is the result of a force acting over some distance. Work is quantified in joules (Nm) or foot-pounds. Torque is a rotating force produced by a motor's crankshaft. The more torque the motor produces, the greater is its ability to perform work. Since torque is a vector acting in a direction it is commonly quantified by the units Nm or pound-feet.
