• ### Understanding required torque for a motor lifting a weight

(0.450 kg)(3 m/s²) = 1.35 N. That, in addition to the 4.4 N just to balance gravity means you need 5.8 N upwards force. At 0.05 m radius, that comes out to a torque of 0.28 Nm. There will be some friction and you want some margin, so in this example a 0.5 Nm motor would do it. Note also that torque isn't the only criterion for a motor.
