Electrical motor nominal torque calculation based on motor nominal power and rotational speed.

**Motor nominal torque**

$$ T_n = {9550 \cdot \left({ {P_n \over n_n} }\right)} $$

This is a generic calculation applicable for squirrel cage electrical motors.

Calculates coupling torque requirements based on electric motor nominal torque and application safety factor.

This is a generic calculation to calculate toque required for coupling selection.

**Required torque**

$$ T_{cn} = {T_n . f_s} $$
