Shaft End And Balancing - Siemens SINAMICS S120 Configuration Manual

Forces due to the rotor weight
Table 3- 10
The values specified apply to standard drive shaft ends; the permissible force loads are
separately specified depending on the individual application for non-standard drive shaft end
dimensions. With forces in excess of these values, please contact your local Siemens office.

Shaft end and balancing

The drive shaft end is cylindrical in accordance with DIN 748 Part 3, IEC 60072-1. The
friction-locked shaft-hub coupling is the preferred option for fast acceleration and reversing
operation of the drives.
Standard:
Options:
The motor balance quality is certified in accordance with DIN ISO 8821.
