Bases: LamSquirrelCage

Rotor lamination for LSPM

VERSION = 1
build_geometry(sym=1, alpha=0, delta=0, is_circular_radius=False)

Build geometry of the LamSquirrelCage

Parameters:

  • self (LamSquirrelCageMag) – A LamSquirrelCageMag 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

  • is_circular_radius (bool) – True to add surfaces to “close” the Lamination radii

Returns:

surf_list – list of surfaces

Return type:

list

check()

Check that the Lamination object is correct

Parameters:

self (LamSquirrelCageMag) – A LamSquirrelCageMag object

Return type:

None

Raises:

  • SCC_NotARotor – A LamSquirrelCage Lamination can’t be a stator

  • SCC_WrongCond – A LamSquirrelCage’s conductor must be a type 2_1

comp_surfaces()

Compute the Lamination surfaces

Parameters:

self (LamSquirrelCageMag) – A LamSquirrelCageMag object

Returns:

S_dict – Lamination surface dictionary (Slam, Svent, Smag, Shole) [m**2]

Return type:

dict

plot(fig=None, ax=None, is_lam_only=False, sym=1, alpha=0, delta=0, is_edge_only=False, edgecolor=None, is_add_arrow=False, is_show_fig=True, is_winding_connection=False)

Plot the Lamination in a matplotlib fig

Parameters:

  • self (LamSquirrelCage) – A LamSquirrelCage 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

  • is_lam_only (bool) – True to plot only the lamination (remove the bare)

  • 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

  • edgecolor – Color of the edges if is_edge_only=True

  • is_show_fig (bool) – To call show at the end of the method

  • is_winding_connection (bool) – True to display winding connections (not used)

Returns:

  • fig (Matplotlib.figure.Figure) – Figure containing the plot

  • ax (Matplotlib.axes.Axes object) – Axis containing the plot

get_pole_pair_number()

save(save_path='', is_folder=False, type_handle_old=2, type_compression=0)

Save the object to the save_path

Parameters:
