Motor Power Pn

The values given in the tables are valid for the following conditions:

The available motor power for different conditions is calculated as follows: P=Pn·fs·ft·fn

Factor fs for different duty type

Duty type fs
S1 Continuous duty. Operation with constant load. The motor reaches the thermal equilibrium. 1.0
S2-10min
S2-30min
S2-60min
Short term duty. Operation with constant load followed by a stop. During the stop the motor returns to the ambient temperature. Described by the duration of the load period in min. 1.4
1.25
1.1
S3-15%ED
S3-25%ED
S3-40%ED
S3-60%ED
Intermittent periodic duty. Operation with a sequence of identical cycles including a time of operation with constant load and a stop. Described by the cyclic duration factor in %. 1.4
1.3
1.2
1.1
S4 .. S10 Intermittent periodic duty. The start or stop phase of the motor is effecting the temperature raise. More data of the duty cycle are necessary. On request

Factor ft for different ambient temperature θ

Factor fh for different altitude h
