VentilationTrap (class)

Method code available at https://github.com/Eomys/pyleecan/tree/master/pyleecan/Methods/Slot/VentilationTrap

class VentilationTrap(Alpha0=0, D0=1, H0=1, W1=1, W2=1, Zh=36, mat_void=-1, magnetization_dict_offset=None, init_dict=None, init_str=None)

Bases: pyleecan.Classes.Hole.Hole

Trapezoidal axial ventilation ducts

VERSION = 1

build_geometry(sym=1, alpha=0, delta=0, is_stator=True)

Compute the curve needed to plot the ventilations

Parameters

• self (VentilationTrap) – A VentilationTrap object

• sym (int) – Symetry to apply 2 = half the machine (Default value = 1 => full machine)

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

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

• is_stator (bool) – True if ventilation is on the stator and 0 on the rotor (Default value = True)

Returns

surf_list – A list of Trapeze

Return type

list

check()

Make sure that the ventialtion parameters are correctly set

Parameters

self (VentilationTrap) – A VentilationTrap object

comp_radius()

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

Parameters

self (VentilationTrap) – A VentilationTrap 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 (VentilationTrap) – A VentilationTrap object

Returns

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

Return type

float

get_center()

Return a list of center of the ventilations :param self: A VentilationTrap object :type self: VentilationTrap

Returns

Zc_list – List of list of center complex coordinates

Return type

list

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(**kwargs)

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

compare(other, name='self')

Compare two objects and return list of differences

as_dict(**kwargs)

Convert this object in a json serializable dict (can be use in __init__). Optional keyword input parameter is for internal use only and may prevent json serializability.
