build_geometry()¶

Compute the curve (Line) needed to plot the object. The ending point of a curve is the starting point of the next curve in the list

Parameters:: self (SlotW28) – A SlotW28 object
Returns:: curve_list – A list of 4 Segment and 3 Arc1
Return type:: list

check()¶

Check that the SlotW28 object is correct

Parameters:

self (SlotW28) – A SlotW28 object

Return type:

None

Raises:

S28_RboW0CheckError – You must have W0/2 < Rbo
S28_R1W3CheckError – W3 is too high comparing to the lamination bore radius (Rbo)
S28_ZsCheckError – There are too many slots to match W3 and R1

comp_angle_opening()¶

Compute the average opening angle of the Slot

Parameters:: self (SlotW28) – A SlotW28 object
Returns:: alpha – Average opening angle of the slot [rad]
Return type:: float

comp_height()¶

Compute the height of the Slot. Caution, the bottom of the Slot is an Arc

Parameters:: self (SlotW28) – A SlotW28 object
Returns:: Htot – Height of the slot [m]
Return type:: float

comp_height_active()¶

Compute the height of the winding area

Parameters:: self (SlotW28) – A SlotW28 object
Returns:: Hwind – Height of the winding area [m]
Return type:: float

comp_surface()¶

Compute the Slot total surface (by analytical computation). Caution, the bottom of the Slot is an Arc

Parameters:: self (SlotW28) – A SlotW28 object
Returns:: S – Slot total surface [m**2]
Return type:: float

comp_surface_opening()¶

Compute the Slot total surface (by analytical computation). Caution, the bottom of the Slot is an Arc

Parameters:: self (SlotW28) – A SlotW28 object
Returns:: S – Slot total surface [m**2]
Return type:: float

get_surface_active(alpha=0, delta=0)¶

Return the full winding surface

Parameters:

self (SlotW28) – A SlotW28 object
alpha (float) – float number for rotation (Default value = 0) [rad]
delta (complex) – complex number for translation (Default value = 0)

Returns:

surf_wind – Surface corresponding to the Winding Area

Return type:

Surface

get_surface_opening(alpha=0, delta=0)¶

Return the list of surfaces defining the opening area of the Slot

Parameters:

self (SlotW28) – A SlotW28 object
alpha (float) – float number for rotation (Default value = 0) [rad]
delta (complex) – complex number for translation (Default value = 0)

Returns:

surf_list – list of surfaces objects

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=1, save_path=None, is_show_fig=True, fig=None, ax=None)¶

Plot the schematics of the slot

Parameters:

self (SlotW28) – A SlotW28 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, 3: active surface as winding + wedges
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 schematics
ax (Matplotlib.axes.Axes object) – Axis containing the schematics

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.
