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

In a ideal system with no friction, the torque to maintain 10 m/s and 1000 m/s is the same, but the power required to produce that torque at the higher speed is 100 times more. If you needed 15 W at 10 m/s, then you'll need 1.5 kW at 1000 m/s. \$endgroup\$ – Olin Lathrop Apr 19 '16 at 21:46

• ### How do you calculate output torque needed to lift a weight ...

How do you calculate output torque needed to lift a weight. Close • Posted by 1 hour ago. How do you calculate output torque needed to lift a weight. I need to lift a 16lbs weight with a 2" spool diameter spool of cable. I think that the calculation for load torque is F*spool diameter, so it would just be 16in-lbs of output torque, right?

• ### torque - What DC motor specs do I need to lift a weight ...

Lifting a certain weight requires tension in the cable, torque through the rest of the geartrain, and current in the motor. Lifting at a certain speed requires m/s at the cable, radians/s through the geartrain, and voltage at the motor. Lifting the weight at a certain speed requires power from end to end, always measured in watts.

• ### Torque Calculator

Enter these values into our torque calculator. It uses the torque equation: τ = rFsin(θ) = 0.5 * 120 * sin(90°) = 60 N·m. The torque calculator can also work in reverse, finding the force or lever arm if torque is given. If you want to learn more about the concept of force and Newton's second law, try the acceleration calculator.

• ### How to Calculate Torque Perpendicular to Where Force Is ...

The magnitude of the torque here is 100 newton-meters. But now take a look at diagram C. You push with 200 newtons of force at a distance of 2r perpendicular to the hinge, which makes the lever arm 2r or 1.0 meter, so you get this torque:. Now you have 200 newton-meters of torque, because you push at a point twice as far away from the pivot point.

• ### torque - How to calculate the weight my DC motor can move ...
