1FK2 synchronous motors for SINAMICS S120

Note
The voltage limit characteristic of a motor with 6000
rpm rated speed is far above that of the
same motor type with 2000
rpm. However, for the same torque, this motor requires a
significantly higher current.
For this reason, you should select the rated speed such that it does not lie too far above the
maximum speed
required for the application.
The size (rating) of the Motor Module (output current) can be minimized in this fashion.
The characteristic data listed in the data sheets fluctuates in a certain range. The following
tolerances apply to the characteristic data:
