S4 - Intermittent periodic duty with starting. Identical duty cycles, significant starting time, constant load, de-energized at rest. FI = (J_L+J_M)/J_M. Stamp e.g.:

S5 - Intermittent periodic duty with electric braking. This is like S4 but with electric brake.

...

S8 - Continuous-operation periodic duty with related load/speed changes. Stamping example:

                                       Image Added

S9 - Duty with non-periodic load and speed variations. The duty includes frequently applied overloads that may greatly exceed the reference load (P_ref is appropriately based on duty type S1).

                      S10: p/Δt = 1,1/0,4; 1/0,3; 0,9/0,2; r/0,1 TL = 0,6 

Alla olevassa kuvassa on esitetty millainen mottorin arvokilpi voisi olla. Huomaa, että moottori vastaa luokkaa S1.

The nominal electrical power can be calculated as shown here:

In the USA, NEMA-standards are followed.
