Power From Torque Formula
The following formula is used to calculate the Power From Torque.
P = t*w
- Where P is the Power From Torque (watts)
- t is the total torque (N-m)
- w is the angular velocity (rad/s)
To calculate power from torque, multiply the torque by the angular velocity.
How to Calculate Power From Torque?
The following two example problems outline how to calculate the Power From Torque.
Example Problem #1:
- First, determine the total torque (N-m). In this example, the total torque (N-m) is measured to be 93.
- Next, determine the angular velocity (rad/s). For this problem, the angular velocity (rad/s) is calculated to be 75.
- Finally, calculate the Power From Torque using the formula above:
P = t*w
Inserting the values from above and solving the equation with the imputed values gives:
P = 93*75 = 6975 (watts)
FAQ
What is torque in the context of motors and machinery?
Torque is a measure of the rotational force applied to an object. In motors and machinery, it represents how much force the motor can apply to turn an object. It is typically measured in Newton-meters (N-m) or foot-pounds (ft-lb) in the imperial system.
How does angular velocity affect the power output of a motor?
Angular velocity, measured in radians per second (rad/s), represents the speed of rotation. The power output of a motor increases with the product of torque and angular velocity. This means that for a given torque, a higher angular velocity will result in a higher power output.
Can the formula for calculating power from torque be used for any type of motor?
Yes, the formula P = t*w, where P is power in watts, t is torque in Newton-meters, and w is angular velocity in radians per second, is a fundamental physics equation that applies to all rotational systems, including all types of motors. However, the specific values of torque and angular velocity may vary depending on the type and efficiency of the motor.
