Katso: IEC 60034-1
Katso: NEMA vs. IEC
International standard IEC 34-1 defines 8, IEC 60034-1 10, different stampings for different ways to use a motor: S1, S2… S10. These are named as follows:
S1 - Continuous running duty. Stamp: S1.
...
S4 - Intermittent periodic duty with starting. Identical duty cycles, significant starting time, constant load, de-energized at rest. FI = (JL+JM)/JM. Stamp e.g.:
S5 - Intermittent periodic duty with electric braking. This is like S4 but with electric brake.
...
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.
Seuraavassa kuvassa on esitetty mahdoliset kytkentätäavatIn the Figure 46, there is shown an example of a value plate of a motor. The connection possibilities to the supply are shown in the Figure 47. Notice, that in both connections the voltage over the windings is 400 V and the current through is 3.8 A. The decimal comma is used in the plate and the pictures, instead of decimal point, according to the IEC standard.

In the USA, NEMA-standards are followed.
