- Calculation Torque
In summary, the conversation is about how to calculate the required torque for a mini servo to move a load on a slider. The mechanism in question is a highly offset slider-crank mechanism. The purpose of the movement is to either hold the load against a constant velocity of 0.5m/s or accelerate the load at a specific rate. The discussion also touches on the limitations of the slider's range and the need to control the crank speed for varying the velocity.

What you have is a highly offset slider-crank mechanism.
Are you concerned with simply holding the slider against a load, or do you want to accelerate the slider? If you want to accelerate the slider, then at what rate? You need to give us a bit more to work with.

I am confused.
How many separate parts are there ?
What can move relative to what ?
What bits are the fixed frame or chassis ?

I want to move the load (it is actually a heater) that was mounted on the slider at 0.5m/s either to the left or right.Dr.D said:

A constant velocity on the velocity will require a variable crank speed. Are you prepared to control crank speed to vary in a specific way?
I hope you are aware that the slider moves only over a limited range. As you approach the ends of the range, the velocity must approach zero in order to reverse. Is this satisfactory for your purposes?

FAQ: How to Calculate Required Torque for Mini Servo on Slider?
What is torque and why is it important?
Torque is a measure of rotational force and is important because it determines an object's ability to rotate or change its angular momentum. In engineering and physics, torque is used to calculate the amount of force needed to rotate an object, such as a bolt or a wheel.
How is torque calculated?
Torque is calculated by multiplying the force applied to an object by the distance from the point of rotation to the point where the force is applied. The formula for torque is T = F x r, where T is torque, F is force, and r is the distance from the point of rotation.
What is the unit of measurement for torque?
The unit of measurement for torque is the Newton-meter (Nm) in the metric system and the foot-pound (ft-lb) in the imperial system. In some cases, torque may also be measured in inch-pounds (in-lb) or kilogram-force meters (kgf-m).
How is required torque calculated for a specific application?
To calculate the required torque for a specific application, you will need to know the force required to rotate the object, the distance from the point of rotation to the point where the force is applied, and the type of motion (e.g. clockwise or counterclockwise). You can then use the formula T = F x r to determine the required torque.
What factors can affect the required torque calculation?
The required torque calculation can be affected by several factors, including the type of material and surface condition of the object, the friction between the object and its surroundings, and the speed and direction of rotation. It is important to consider all these factors when calculating the required torque for a specific application.
