Winding abstract class

VERSION = 1
comp_Ncspc(Zs=None)

Compute the number of coils in series per parallel circuit

Parameters:
  • self (Winding) – A Winding object
  • Zs (int) – number of slot
Returns:

Ncspc – Number of coils in series per parallel circuit
Return type:

float
comp_Ntspc(Zs=None)

Compute the number of turns in series per phase

Parameters:
  • self (Winding) – A Winding object
  • Zs (int) – Number of slot
Returns:

Ntspc – Number of turns in series per phase
Return type:

float
comp_phasor_angle(Zs=None)

Compute the phasor angle of the winding phases related to the first slot

Parameters:
  • self (Winding) – A: Winding object
  • Zs (int) – Number of Slot (Integer >0)
Returns:

angle_vec – Phasor Angle Vector (qs)
Return type:

numpy.ndarray
comp_resistance_norm(T=20)

Compute the winding resistance per meter, i.e. winding resistance divided by coil side length (including end winding). The actual winding resistance is comp_resistance_norm * (length_active + length_end_winding)

Parameters:
  • self (Winding) – A Winding object
  • T (float) – Winding Temperature [°C]
Returns:

winding_resistance_norm – normalized winding resistance
Return type:

float
comp_winding_factor(Harmonics=[1])

Compute the winding factor of phase 1 (asuming symmetry)

Parameters:
  • self (Winding) – A: Winding object
  • Harmonics (list of floats) – list of harmonics to calculate the winding factor
Returns:

xi – winding factor
Return type:

numpy.ndarray
save(save_path='')

Save the object to the save_path

Parameters:
  • self – A pyleecan object
  • save_path (str) – path to the folder to save the object
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
as_dict()[source]

Convert this objet in a json seriable dict (can be use in __init__)

is_reverse_wind

1 to reverse the default winding algorithm along the airgap (c, b, a instead of a, b, c along the trigonometric direction)

Nslot_shift_wind

0 not to change the stator winding connection matrix built by pyleecan number of slots to shift the coils obtained with pyleecan winding algorithm (a, b, c becomes b, c, a with Nslot_shift_wind1=1)

qs

number of phases

Ntcoil

number of turns per coil

Npcpp

number of parallel circuits per phase (maximum 2p)

type_connection

0 star (Y), 1 triangle (delta)

Type:Winding connection
p

pole pairs number

Lewout

straight length of the conductors outside the lamination before the curved part of winding overhang [m] - can be negative to tune the average turn length

conductor

Winding’s conductor
