class VentilationPolar(D0=1, H0=1, W1=1, Zh=36, mat_void=- 1, magnetization_dict_offset=None, Alpha0=0, init_dict=None, init_str=None)[source]

Bases: Hole

Polar axial ventilation duct

VERSION = 1
build_geometry(alpha=0, delta=0)

Compute the curve needed to plot the ventilations

Parameters:

  • self (VentilationPolar) – A VentilationPolar object

  • alpha (float) – Angle for rotation (Default value = 0) [rad]

  • delta (complex) – Complex for translation (Default value = 0)

Returns:

surf_list – A list of PolarArc

Return type:

list

Raises:

PolarArcBuildGeometryError – The parameter ‘sym’ must be an integer > 0 The parameter ‘alpha’ must be an int or float The parameter ‘delta’ must be a complex or float or int number

check()

Make sure that the ventilation parameters are correctly set

Parameters:

self (VentilationPolar) – A VentilationPolar object

Return type:

None

Raises:

VentilationPolarInstanceError – Zh must be a integer H0 must be a float or int D0 must be a float or int Alpha0 must be a float or int

comp_radius()

Compute the radius of the two circle that contains all the ventilation ducts

Parameters:

self (VentilationPolar) – A VentilationPolar object

Returns:

(Rmin, Rmax) – Tuple of circle radius [m]

Return type:

tuple

comp_surface()

Compute the surface of all the axial ventilation ducts

Parameters:

self (VentilationPolar) – A VentilationPolar object

Returns:

surface – Axial ventilation ducts total surface [m**2]

Return type:

float

get_center()

Return a list of the center of the ventilations

Parameters:

self (VentilationPolar) – A VentilationPolar object

Returns:

Zc_list – List of list of center complex coordinates

Return type:

list

plot_schematics(is_default=False, is_add_point_label=False, is_add_schematics=True, is_add_main_line=True, type_add_active=True, save_path=None, is_show_fig=True, fig=None, ax=None)

Plot the schematics of the slot

Parameters:

  • self (VentilationPolar) – A VentilationPolar object

  • is_default (bool) – True: plot default schematics, else use current slot values

  • is_add_point_label (bool) – True to display the name of the points (Z1, Z2….)

  • is_add_schematics (bool) – True to display the schematics information (W0, H0…)

  • is_add_main_line (bool) – True to display “main lines” (slot opening and 0x axis)

  • type_add_active (int) – 0: No active surface, 1: active surface as winding, 2: active surface as magnet

  • save_path (str) – full path including folder, name and extension of the file to save if save_path is not None

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

  • 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

Returns:

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

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

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

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 (json only)

  • type_handle_old (int) – How to handle old file in folder mode (0:Nothing, 1:Delete, 2:Move to “Backup” folder)

  • type_compression (int) – Available only for json, 0: no compression, 1: gzip

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

compare(other, name='self', ignore_list=None, is_add_value=False)[source]

Compare two objects and return list of differences

as_dict(type_handle_ndarray=0, keep_function=False, **kwargs)[source]

Convert this object in a json serializable dict (can be use in __init__). type_handle_ndarray: int

How to handle ndarray (0: tolist, 1: copy, 2: nothing)

keep_functionbool

True to keep the function object, else return str

Optional keyword input parameter is for internal use only and may prevent json serializability.

copy()[source]

Creates a deepcopy of the object
