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, init_dict=None, init_str=None)[source]¶

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()¶: 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
