Service factor

Every gearmotor was assigned a service factor in the SEW catalog. The service factor is the ratio between gear unit rated power and rated motor power. There are no standards on how to determine service factors. This is why service factors vary from manufacturer to manufacturer and cannot be compared.


Example:

R47DRN90L4 / i=23,28 / Ma [Nm] = 225 / fB 1,3
R47 - Mamax [Nm] = 300
Mamax / Ma = fB
300 Nm / 225 Nm = 1,33 (~1,3)


Refer to the catalog for more information:

International efficiency class (IE)
Especially low output speeds
By activating "especially low speed", the search for the motor power and service factor will be ignored. Mamax [Nm] must be adhered to because the motor can overload the gear unit.
