11/4/ 32 Maybe you should ignore power at first and use torque T the torque is deemed to be constant calculate the acceleration rate α in rad/sec/sec ive attached a sheet to use then calculate the torque T in N m from T = I α I = flywheel moment of inertia kgTherefore the torque lbs in or pounds at one inch requirements will be torque = 50 1/10 /2 pi or 5 / We will leave out the efficiency of the screw/nut combination for simplicity We get a value of about lbs in Now your thinking that number

Usually for small motors maximum power is at 50 of stall torque approximately 50 of no load speed Maximum efficiency may be 10 30 of motor stall torque 70 90 of no load speed While it is technically better to follow the same format and create similar curves for your motor it is not absolutely necessary for a good science projectDifferent engine designs/configurations develop different torque characteristics such as peak curve/flat curveMost automotive engines produce useful torque output within a narrow band of the engine’s entire speed range In petrol engines it characteristically starts at around rpm and reaching a peak in the range of 2 500 4 000 rpm
