1. What is the Linear Actuator Force Equation?

The Linear Actuator Force Equation calculates the force output of an electric linear actuator based on the input current and a constant that represents the actuator's force-to-current ratio.

2. How Does the Calculator Work?

The calculator uses the linear actuator force equation:

Where:

• \( Current \) — Electrical current in Amperes (A)
• \( Constant \) — Actuator-specific constant in Newtons per Ampere (N/A)

Explanation: The equation shows the direct proportional relationship between current and force output for a given linear actuator.

3. Importance of Force Calculation

Details: Accurate force calculation is crucial for selecting the right actuator for an application, ensuring it can handle the required load without being oversized.

4. Using the Calculator

Tips: Enter the current drawn by the actuator in Amperes and the actuator's force constant in N/A. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where do I find the actuator constant?
A: The constant is typically provided in the actuator's specifications or can be determined experimentally by measuring force output at known currents.

Q2: Does this equation work for all linear actuators?
A: This simplified equation works best for electric linear actuators where force is directly proportional to current. Other types may require more complex calculations.

Q3: What are typical constant values?
A: Constants vary by actuator but typically range from 10-100 N/A depending on the actuator's size and design.

Q4: Does temperature affect the calculation?
A: Yes, temperature can affect both the actuator's performance and resistance, which may require compensation in precise applications.

Q5: How accurate is this calculation?
A: It provides a good estimate, but real-world factors like efficiency losses, friction, and voltage variations may affect actual performance.
