Bases: FrozenClass

Electric module object for electrical equivalent circuit simulation

VERSION = 1
run()

Run the Electrical module

comp_power(out_dict, machine)

Compute the electrical average power

Parameters:

  • self (Electrical) – an Electrical object

  • out_dict (dict) – Dict containing all magnetic quantities that have been calculated in comp_parameters of EEC

comp_torque(out_dict, N0)

Compute the electrical average torque

Parameters:

  • self (Electrical) – an Electrical object

  • out_dict (dict) – Dict containing all magnetic quantities that have been calculated in comp_parameters of EEC

gen_drive(output)

Generate the drive for the equivalent electrical circuit (only PWM drive for now)

Parameters:

  • self (Electrical) – an Electrical object

  • output (Output) – an Output object

save(save_path='', is_folder=False, type_handle_old=2, type_compression=0)

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 (json only)

  • type_handle_old (int) – How to handle old file in folder mode (0:Nothing, 1:Delete, 2:Move to “Backup” folder)

  • type_compression (int) – Available only for json, 0: no compression, 1: gzip

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', ignore_list=None, is_add_value=False)[source]

Compare two objects and return list of differences

as_dict(type_handle_ndarray=0, keep_function=False, **kwargs)[source]

Convert this object in a json serializable dict (can be use in __init__). type_handle_ndarray: int

How to handle ndarray (0: tolist, 1: copy, 2: nothing)

keep_functionbool

True to keep the function object, else return str

Optional keyword input parameter is for internal use only and may prevent json serializability.

copy()[source]

Creates a deepcopy of the object
