Bearings inputs

1. Overview



SHAFT – Bearing - Design area
1 Selection of the MACHINE subset: SHAFT panel (Click on the icon SHAFT)
2 Visualization of the motor axial view to visualize the shaft topology with bearings
3 Shaft section to define the shaft parameters
4 When there is a shaft, the section of Bearing is unlocked
5 Choice of the shaft-Bearing type. Two types are available:
  • None: No dimensions to be declared. There is no bearing.
  • With bearings: Bearings’ characteristics must be defined - Structural data of bearings are then edited
6 Shaft-Bearing input data to be defined
7 Button to restore default input values
8 Button to Apply inputs. Pressing the enter key twice applies inputs too.
9 Icon to export shaft data into *.txt or *.xlsx files.
Important: When “None” is selected, access to Internal cooling environment is locked.

2. Shaft-Bearing type and characteristics

Two types of shaft can be selected:

  • None: There is no bearing in the rotor design = No dimension to declare.
  • With bearings: Shaft-Bearings are represented and considered in the rotor design.




Shaft-Bearing type: None Shaft-Bearing type: With bearings




Dimensions are illustrated with arrows Connection side (C.S.) is identified by yellow lightning.
