Instructions on selection of product and motor

For correctly selecting a gear reducer or geared motor, several essential pieces of data are required:
1. The rotational input speed to the gear reducer (n1) and the rotational output speed (n2). Through these two values it
is possible to calculate the reduction ratio (i) of the gear reducer using the following formula: i=n1/n2
2. The torque required by the application (Mr2). The geared motor or gear reducer can be selected once this data is

known.This guide helps you to select the right product in just a few steps:
Geared motor selection
1. Determine the application’s actual service factor (s.f.). This parameter depends on the type of load of the powered
machine, the number of starts per hour and the hours of operation (refer to the "Service factor" paragraph).

2. Calculate the input power Pr1 using the required torque value Mr2, the speed n2 and dynamic efficiency value.

Pr1=(Mr2*n2)/(9550*ηd). The dynamic efficiency value depends on the type of gear reducer and on the number of

gear reduction stages. (To calculate the efficiency value see its page).

3. Consult the geared motor performance tables and identify a normalised power value Pn1 exceeding the required
power Pr1, such that: Pn1≥Pr1
4. Once the suitable nominal power has been identified, select the geared motor capable of generating the rotational
speed closest to the desired n2 value and with service factor s.f. greater or equal to that required by the application.
