Siemens SIMOTICS T-1FW6 - Forces that Occur between the Stator and Rotor

CAUTION
Sharp edges and falling objects
Sharp edges can cause cuts and falling objects can injure feet.
• Always wear safety shoes and safety gloves!

Radial forces between the stator and rotor
The following table shows the active radial forces in N per 0.1 mm centering error between the
stator and rotor. The longer the active component, the greater the radial force.
