The term “servo” in mechanics refers to an automatic device that uses error-sensing negative feedback to correct the performance of a mechanism. On the other hand, “torque” signifies a measure of the force that can cause an object to rotate around an axis. Consequently, a Servo Torque is the force generated by a servo motor that contributes to the movement of the object it is attached to.
A Servo Torque Calculator, as the name suggests, is a practical tool for computing the torque generated by a servo motor. This calculator utilizes a specific formula to derive the servo torque, which is crucial in various engineering applications.
Working of the Servo Torque Calculator
The Servo Torque Calculator operates using a specific formula that combines several variables. Each of these variables plays a crucial role in the computation of servo torque. When using this calculator, you input the variables, and the tool applies them to the formula to calculate the Servo Torque.
Servo Torque Formula & Variables
The Servo Torque Calculator employs the following formula:
Tservo=I∗α+m∗g∗r/2
In this formula:
- Tservo is the Servo Torque (N-m)
- I is the moment of inertia (kg-m^2)
- α is the angular acceleration (rad/s^2)
- m is the mass (kg)
- g is the acceleration due to gravity (9.81 m/s^2)
- r is the radius (m)
The moment of inertia (I) refers to the measure of an object’s resistance to changes in its rotation. The angular acceleration (α) signifies how quickly an object’s rotational speed changes. The mass (m) is the amount of matter in the object. Gravity’s acceleration (g) is a constant value in physics, representing the rate at which objects accelerate toward the earth. Lastly, the radius (r) represents the straight-line distance from the center of the circle to its circumference.
Detailed Example
Let’s use a specific example to understand how the Servo Torque Calculator works:
Suppose we have:
- Moment of inertia (I): 5 kg-m^2
- Angular acceleration (α): 12 rad/s^2
- Mass (m): 4 kg
- Radius (r): 5 m
By substituting these values into the formula, we have:
Tservo = (512) + ((49.81*5)/2) = 158.1 N-m
Therefore, the Servo Torque in this case is 158.1 Newton meters (N-m).
