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(**kwargs)

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

compare(other, name='self')

Compare two objects and return list of differences

as_dict(**kwargs)

Convert this object in a json serializable dict (can be use in __init__). Optional keyword input parameter is for internal use only and may prevent json serializability.
