Forces module abstract object

VERSION = 1

run()

Run the Force module

comp_axes(output)

Compute the axes required in any Force module

Parameters:

• self (Force) – a Force object

• output (Output) – an Output object (to update)

Returns:

axes_dict – Dict containing Time and Angle axes including (anti-)periodicties used in any Force module

Return type:

comp_AGSF_transfer(output, rnoise=None)

Method to compute Air-Gap Surface Force transfer from middle air-gap radius to stator bore radius.

From publication:

PILE, Raphaël, LE BESNERAIS, Jean, PARENT, Guillaume, et al. Analytical study of air-gap surface force–application to electrical machines. Open Physics, 2020, vol. 18, no 1, p. 658-673. https://www.degruyter.com/view/journals/phys/18/1/article-p658.xml

Parameters:

• self (Force) – a Force 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)

Compare two objects and return list of differences

as_dict(type_handle_ndarray=0, keep_function=False, **kwargs)

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()

Creates a deepcopy of the object

property is_periodicity_t

True to compute only on one time periodicity (use periodicities defined in axes_dict[time]). If None, automatically calculated based on Magnetics periodicities.

Type:

bool

property is_periodicity_a

True to compute only on one angle periodicity (use periodicities defined in axes_dict[angle]). If None, automatically calculated based on Magnetics periodicities.

Type:

bool

property is_agsf_transfer

True to compute the AGSF transfer from air-gap to stator bore radius.

Type:

bool

property max_wavenumber_transfer

Maximum value to apply agsf transfer (to be used with FEA to avoid numerical noise amplification)

Type:

int

property Rsbo_enforced_transfer

To enforce the value of the radius for AGSF transfer

Type:

float

property logger_name

Name of the logger to use

Type:

str
