# Calculating time for Linear actuator to operate?

• mm391
In summary, the conversation discusses a linear actuator that can produce a force of up to 4000 Newtons when pressure is applied. The actuator operates at a maximum speed of 11mm/s with no force and a minimum speed of 8mm/s at maximum force, with the speed decreasing linearly in between. The question asked is whether the "suvat" equations can be used to calculate the time it takes for the actuator to fully extend from 0 Newtons to 4000 Newtons by rearranging them for the desired value. The need for further clarification on when the force acts on the actuator and when its speed changes is also mentioned.

I have a linear actuator operating on an object that, when pressure acts against it, produces a force up to 4000 Newtons.

The linear actuator operates with a maximum speed of 11mm/s at no force and a minimum speed at maximum force of 8mm/s. Being a linear actuator the speed decrease linearly from 11mm/s to 8mm/s. Is there a way of calculating the time it will take the linear actuator to fully extend 1.7mm from 0 Newtons to 4000 Newtons?

Is it the basic "suvat" equations:

s=((u+v)/2)*t
s=u*t+0.5*a*t^2

and just rearrange them for the vale you want?

I think the basic equations might suffice. Could you please explain a bit clearly as to when the force acts on the actuator and when it's speed starts changing? (Maybe with a diagram)

## 1. How do I calculate the time it will take for a linear actuator to operate?

To calculate the time for a linear actuator to operate, you will need to know the distance the actuator needs to travel, the speed of the actuator, and the load that the actuator is moving. Using the formula time = distance / speed, you can calculate the approximate time it will take for the linear actuator to operate.

## 2. What is the speed of a linear actuator?

The speed of a linear actuator is typically measured in inches per second (IPS) or millimeters per second (mm/s). The speed can vary depending on the type and size of the actuator, as well as the load it is moving.

## 3. How does the load affect the time for a linear actuator to operate?

The load that a linear actuator is moving can affect the time it takes for the actuator to operate. A heavier load will require more force to move, which can slow down the actuator's speed and increase the operating time. It is important to consider the load when calculating the time for a linear actuator to operate.

## 4. Can I adjust the speed of a linear actuator?

Yes, the speed of a linear actuator can be adjusted by changing the voltage or current supplied to the actuator. However, it is important to follow the manufacturer's guidelines and not exceed the recommended speed for the actuator, as this can cause damage or reduce the lifespan of the actuator.

## 5. Are there any other factors that can affect the time for a linear actuator to operate?

Yes, there are other factors that can affect the time for a linear actuator to operate. These include the type and design of the actuator, the power source and voltage, the environmental conditions (such as temperature and humidity), and the type of load being moved. It is important to consider all of these factors when calculating the time for a linear actuator to operate.
