class Shaft(Lshaft=0.442, mat_type=-1, Drsh=0.045, init_dict=None, init_str=None)[source]

Bases: pyleecan.Classes._frozen.FrozenClass

machine shaft

VERSION = 1
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

logging.Logger
