Siemens S120 Technical data and characteristics, Explanations of the formula abbreviations

Technical data and characteristics 14

The technical data and characteristics for the 1FW6 Built-in torque motors are specified in this Chapter. This data collection provides the motor data required for configuration and contains a number of additional data for more detailed calculations for detailed analyses and problem analyses. Technical data subject to change.

Note

System-specific data refer to the combination of built-in torque motors 1FW6 with

SINAMICS S120 drive systems.

Unless otherwise specified, the following boundary conditions apply here:

∙The DC link voltage UZK is 600 V, while the converter output voltage Uamax is 425 V.

∙The motor is water-cooled with the recommended minimum flow rate according to the data sheet and a water intake temperature TVORL of 35 °C

∙The rated temperature of the motor winding TN is 130 °C

∙Voltages and currents are specified as rms values.

∙Installation altitude of the motors up to 4000 m above sea level.

∙For motors with integrated cooling, the performance data has been determined with the use of a cooling connection adapter.
