Rectangular slot for buried magnet

VERSION = 1
IS_SYMMETRICAL = 1
build_geometry(alpha=0, delta=0, is_simplified=False)

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 (HoleM52) – A HoleM52 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 SurfLine needed to draw the HoleM51

Return type:

list

check()

Check that the HoleM52 object is correct

Parameters:

self (HoleM52R) – A HoleM52R object

Return type:

None

Raises:

  • S52R_H12CheckError – You must have H2 < H1

  • S52R_alphaCheckError – The teeth are too wide for the lamination (reduce W3 or H0)

  • S52R_W1CheckError – W1 is <=0, you must reduce W0 or W3

comp_alpha()

Parameters:

  • self (HoleM51) – A HoleM51 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

  • save_path (str) – full path including folder, name and extension of the file to save if save_path is not None
