### Gearhead Efficiencies

Posted:

**Tue Mar 23, 2021 12:13 pm**When Calculating Output torque of an AC or BLDC motor, the equation is as follows:

The gearhead output torque increases proportionally as the gear ratio increases. However, the load torque is saturated at a certain gear ratio because of the gear materials and other conditions. This torque is called the maximum permissible torque and maximum torque a given motor and gearhead can produce.

Theoretical output torque is the output torque calculated if not accounting for maximum permissible torque.

To find maximum permissible torque, reference the product page for your selected motor.

From the charts below you can find the efficiency of your gearhead:
