Duty types
Line operation
The three-phase AC motors are designed for duty type S1
according to IEC 60034 (continuous duty).
Inverter operation
For inverter operation (
P91, P92
), the motors with the applicable
voltages are also stamped with duty type Inv. Duty.
Depending on the selected voltage, the technical specifications
for the operating points at 50 Hz, 60 Hz and 87 Hz are stated on
the rating plate.
With IE2 motors rated for 0.75 kW and above that fall within the
scope of the Eco-design Directive (EC) No. 640/2009, the notice
"IE2 Inv. Duty only" is also attached to the motor.
■
Standard voltages
Three-phase AC motors are available for rated voltages ranging
from 200 up to 690 V.
Motor frame sizes 63 up to 112 are generally supplied for the
voltage range 230/400 V at 50 Hz.
The standard version is 400/690 V at 50 Hz for motor frame
size 132.
At the customer's request, we can stamp a tolerance of ±10 %
on the rating plate for a number of our standard voltages.
