Bases: pyleecan.Classes.HoleMag.HoleMag

V shape slot for buried magnet

VERSION = 1

IS_SYMMETRICAL = 1

build_geometry(alpha=0, delta=0, is_simplified=False)

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

Parameters

• self (HoleM53) – A HoleM53 object

• alpha (float) – Angle to rotate the slot (Default value = 0) [rad]

• delta (complex) – Complex to translate the slot (Default value = 0)

• is_simplified (bool) – True to avoid line superposition

Returns

surf_list – List of Magnet Surface and Air Surface on the slot

Return type

list

check()

Check that the HoleM53 object is correct

Parameters

self (HoleM53) – A HoleM53 object

Returns

Return type

None

Raises

• S53_Rext0CheckError – You must have H0 < Rext

• S53_Rext1CheckError – You must have H1 < Rext

• S53_W4CheckError – You must have W4 < pi/2

• S53_W5CheckError – You must have W5 >=0

comp_alpha()

Compute the magnets angle of the slot type 53

Parameters

self (HoleM53) – a HoleM53 object

Returns

alpha – magnet angle [rad]

Return type

float

comp_radius()

Compute the radius of the min and max circle that contains the hole

Parameters

self (HoleM53) – A HoleM53 object

Returns

(Rmin,Rmax) – Radius of the circle that contains the hole [m]

Return type

tuple

comp_W5()

Compute the W5 width of the hole (cf schematics)

Parameters

self (HoleM53) – a HoleM53 object

Returns

W5 – Cf schematics [m]

Return type

float

Raises

Slot53InterError – ERROR: Slot 53, Can’t find Z11 coordinates

has_magnet()

Return if the Hole has magnets

Parameters

self (HoleM53) – A HoleM53 object

Returns

has_magnet – True if the magnets are not None

Return type

bool

remove_magnet()

Remove the magnet (set to None) of the Hole

Parameters

self (HoleM53) – a HoleM53 object

comp_surface_magnet_id(index)

Compute the surface of the hole magnet of the corresponding index

Parameters

• self (HoleM53) – A HoleM53 object

• index (int) – Index of the magnet to compute the surface

Returns

Smag – Surface of the Magnet [m**2]

Return type

float

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
