Design

Type of shaft

The design of the machine can be considered with or without a shaft. Hence, two solutions are proposed:
  • None: The shaft is not represented and not considered in the rotor design. It is replaced by fluid (like air).
  • With shaft: The shaft is represented and considered in the rotor design.
Note: The shaft can be built only with solid material.

Shaft type: None Shaft type: Solid

The dimensions are illustrated with arrows. The connection side (C.S.) is identified by yellow lightning.

Type of shaft topology

Four types of shaft topology are proposed and illustrated below.

Shaft topology 1: Solid Shaft Shaft topology 2: Solid with hollow
Table 4. Type of shaft topology




Shaft topology 3: Solid with ring Shaft topology 4: Solid with hollow and ring

Inputs – Validity domain

  1. Solid shaft inputs:
    • Rotating shaft (ROT) - Yes / No
    • C.S. diameter (D1) - Connection side end-shaft diameter:]0, 20000] mm
    • C.S. extension (L1) - Connection side end-shaft extension:]0, 20000] mm
    • O.C.S. diameter (D2) - Opposite connection side end-shaft diameter:]0, 20000] mm
    • O.C.S. extension (L2) - Opposite connection side end-shaft extension:]0, 20000] mm
  2. Solid shaft with hollow inputs:

    Idem Solid shaft inputs +

    • Hollow shaft diameter (D0) - Inner diameter of hollow shaft:]0, 20000] mm
  3. Solid shaft with ring inputs:

    Idem Solid shaft inputs +

    • Ring thickness (THR) - Ring thickness:]0, 20000] mm
  4. Solid shaft with hollow and ring inputs:

    Idem Solid shaft inputs +

    • Hollow shaft diameter (D0) - Inner diameter of hollow shaft:]0, 20000] mm
    • Ring thickness (THR) - Ring thickness:]0, 20000] mm

Fix and rotating parts

The rotor can be set as a rotating part or not.

There is a way for displaying the rotating parts or the fixed part.
Note: In the list of user inputs, the “Rotating shaft” (Yes / No) allows to consider that the rotor rotates or not. Based on this property, it is possible to display the regions that rotate or that are fixed. A right click of the mouse opens a dialog box allowing it to display all parts or either Rotating parts or Fixed parts. The parts are displayed considering the previous choice. See the illustrations below.
Table 5. Shaft design area – Displaying of rotating parts of the motor


1 The shaft is set as a rotating part.
2 The right click of the mouse opens a dialog box allowing it to display all rotating parts.
Table 6. Shaft design area – Displaying of fixed parts of the motor


1 The shaft is set as a rotating part.
2 The right click of the mouse opens a dialog box allowing it to display all fixed parts.
Note: The drop-down menu allows you to display all parts, to manage the zooming and to export a picture.
