    Lift Load
In summary, the conversation was about determining the torque, power, and rpm needed to lift a 4 kg load vertically in 10 seconds using a 6 volt dc gear motor connected to a 12 mm dia acme lead screw with a 3 mm pitch and 48% efficiency. The load guide is a steel tube with a brass bearing and the needed information can be found in the linked article about leadscrews. The work, power, rpm, and torque can be calculated using the given information.

Hi All.
I am looking to determine the torque/power/rpm. needed to lift a 4 kg. load
150 mm vertically in 10 seconds.
I need to use a 6 volt dc. gear motor mounted vertically and connected to a 12 mm
dia. acme lead screw ( steel ) with a 3 mm pitch and 48 % efficiency.
The lead screw nut witch the load is connected to is also steel.
The load guide is a steel tube with a brass bearing.
Please see attached drawing.

Best regards and thanks in advance.

All of the needed information is in that post. Start with the definition of work to find the work required to lift the weight. then divide by time to find the power. Then divide by efficiency to get the input power needed.

The pitch of the screw tells you how far the weight moves every time the shaft rotates once, from which you can find rpm.

With power and rpm, you can find torque.

Just give it a try with what you already know.
 

1. How is torque related to lifting a load?

Torque is the rotational force that is applied to an object. When lifting a load, the torque is responsible for moving the object in a circular motion around a pivot point, such as a fulcrum.

2. What factors affect the amount of torque needed to lift a 4 kg load?

The amount of torque needed to lift a 4 kg load depends on the distance from the pivot point to the load, the weight of the load, and the force applied to lift the load.

3. How can I calculate the torque needed to lift a 4 kg load?

The torque needed to lift a 4 kg load can be calculated by multiplying the weight of the load by the distance from the pivot point to the load. This will give you the torque in newton-meters (Nm).

4. What is the relationship between torque and power when lifting a 4 kg load?

Power is the rate at which work is done. When calculating the power needed to lift a 4 kg load, the torque is one of the factors that affects the amount of power required. The higher the torque, the more power is needed to lift the load.

5. Is there a specific formula for calculating torque and power in lifting a 4 kg load?

Yes, the formula for calculating torque is: torque = force x distance and the formula for calculating power is: power = torque x angular velocity. By substituting the values for force, distance, and angular velocity, you can calculate the torque and power needed to lift a 4 kg load.
