## Alternator Torque Formula

The following two example problems outline the steps and information needed to calculate the Alternator Torque.

AT = 9.5488 * P / S

Variables:

- AT is the Alternator Torque (N-m)
- P is the alternator power (W)
- S is the alternator speed (RPM)

To calculate the alternator torque, divided the power by the speed, then multiply by 9.5488.

## How to Calculate Alternator Torque?

The following steps outline how to calculate the Alternator Torque.

- First, determine the alternator power (W).
- Next, determine the alternator speed (RPM).
- Next, gather the formula from above = AT = 9.5488 * P / S.
- Finally, calculate the Alternator Torque.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

alternator power (W) = 300

alternator speed (RPM) = 215

AT = 9.5488 * P / S** **= ?
