VERSION = 1
get_Nr()

Create speed in function of time vector Nr

Parameters

self (OutElec) – An OutElec object

Returns

Nr – speed in function of time

Return type

ndarray

get_Is()

Return the stator current DataTime object

Parameters

self (OutElec) – an OutElec object

get_Us()

Return the stator voltage

comp_I_mag(time, is_stator, phase=None)

Compute the current on the given lamination and time vector to use it in Magnetics model Phase currents are divided by the number of parallel circuits per pole and per phase to account for actual current in slot conductors

Parameters

  • self (OutElec) – an OutElec object

  • time (ndarray) – Time vector on which to interpolate currents stored in OutElec

  • is_stator (bool) – True if lamination is stator

  • per_a (int) – (Anti-)periodicity factor

Returns

I – Current matrix accounting for periodicities [q_pera,len(time)]

Return type

ndarray

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
