Bases: pyleecan.Classes.SlotWind.SlotWind

VERSION = 1
IS_SYMMETRICAL = 1
build_geometry()

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

Parameters:self (SlotW28) – A SlotW28 object
Returns:curve_list – A list of 4 Segment and 3 Arc1
Return type:list
build_geometry_wind(Nrad, Ntan, is_simplified=False, alpha=0, delta=0)

Split the slot winding area in several zone

Parameters:
  • self (SlotW28) – A SlotW28 object
  • Nrad (int) – Number of radial layer
  • Ntan (int) – Number of tangentiel layer
  • is_simplified (bool) – boolean to specify if coincident lines are considered as one or different lines (Default value = False)
  • alpha (float) – Angle for rotation (Default value = 0) [rad]
  • delta (Complex) – complex for translation (Default value = 0)
Returns:

surf_list – List of surface delimiting the winding zone

Return type:

list

check()

Check that the SlotW28 object is correct

Parameters:

self (SlotW28) – A SlotW28 object

Returns:

Return type:

None

Raises:
  • S28_RboW0CheckError – You must have W0/2 < Rbo
  • S28_R1W3CheckError – W3 is too high comparing to the lamination bore radius (Rbo)
  • S28_ZsCheckError – There are too many slots to match W3 and R1
comp_angle_opening()

Compute the average opening angle of the Slot

Parameters:self (SlotW28) – A SlotW28 object
Returns:alpha – Average opening angle of the slot [rad]
Return type:float
comp_height()

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

Parameters:self (SlotW28) – A SlotW28 object
Returns:Htot – Height of the slot [m]
Return type:float
comp_height_wind()

Compute the height of the winding area

Parameters:self (SlotW28) – A SlotW28 object
Returns:Hwind – Height of the winding area [m]
Return type:float
comp_surface()

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

Parameters:self (SlotW28) – A SlotW28 object
Returns:S – Slot total surface [m**2]
Return type:float
