build_geometry
(sym=1, alpha=0, delta=0)¶ Build the geometry of the shaft
- Parameters
self (Shaft) – Shaft Object
sym (int) – Symmetry factor (1= full machine, 2= half of the machine…)
alpha (float) – Angle for rotation [rad]
delta (complex) – Complex value for translation
- Returns
surf_list – list of surfaces needed to draw the lamination
- Return type
list
-
comp_mass
()¶ Computation of the Shaft mass
- Parameters
self (Shaft) – A Shaft object
- Returns
M_shaft – Mass of the Shaft [kg]
- Return type
float
-
plot
(fig=None, ax=None, sym=1, alpha=0, delta=0, is_edge_only=False, is_show_fig=True)¶ Plot the Shaft in a matplotlib fig
- Parameters
self (Shaft) – A Shaft object
fig (Matplotlib.figure.Figure) – existing figure to use if None create a new one
ax (Matplotlib.axes.Axes object) – Axis on which to plot the data
sym (int) – Symmetry factor (1= full machine, 2= half of the machine…)
alpha (float) – Angle for rotation [rad]
delta (complex) – Complex value for translation
is_edge_only (bool) – To plot transparent Patches
is_show_fig (bool) – To call show at the end of the method
- Returns
- Return type
None
-
save
(save_path='', is_folder=False)¶ Save the object to the save_path
- Parameters
self – A pyleecan object
save_path (str) – path to the folder to save the object
is_folder (bool) – to split the object in different files: separate simulation machine and materials
-
copy
()¶ Return a copy of the class

get_logger
()¶ Get the object logger or its parent’s one
- Parameters
obj – A pyleecan object
- Returns
logger – Pyleecan object dedicated logger
- Return type
