class SlotDC(W1=0.0122, H1=0.0122, D1=0.001, W2=0.0122, H2=0.001, D2=0.001, H3=0.001, R3=0.001, Zs=36, wedge_mat=None, is_bore=True, init_dict=None, init_str=None)

Bases: Slot

Slot with two rods (for double squirrel cage)

VERSION = 1

IS_SYMMETRICAL = 1

build_geometry()

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

Parameters:

self (SlotDC) – A SlotDC object

Returns:

curve_list – A list of 6 Segment and 5 Arc

Return type:

list

get_surface_active(alpha=0, delta=0)

Return the full winding surface

Parameters:

• self (SlotDC) – A SlotDC 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

check()

Check that the SlotDC object is correct

Parameters:

self (SlotDC) – A SlotDC object

Return type:

None

comp_angle_opening()

Compute the average opening angle of the Slot

Parameters:

self (SlotDC) – A SlotDC object

Returns:

alpha – Average opening angle of the slot [rad]

Return type:

float

comp_height()

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

Parameters:

self (SlotDC) – A SlotDC object

Returns:

Htot – Height of the slot [m]

Return type:

float

comp_height_active()

Compute the height of the winding area

Parameters:

self (SlotDC) – A SlotDC object

Returns:

Hwind – Height of the winding area [m]

Return type:

float

comp_surface()

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

Parameters:

self (SlotDC) – A SlotDC object

Returns:

S – Slot total surface [m**2]

Return type:

float

comp_surface_active()

Compute the Slot inner surface for winding (by analytical computation)

Parameters:

self (SlotDC) – A SlotDC object

Returns:

Swind – Slot inner surface for winding [m**2]

Return type:

float

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)

Compare two objects and return list of differences

as_dict(type_handle_ndarray=0, keep_function=False, **kwargs)

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()

Creates a deepcopy of the object
