class ForceMT(is_periodicity_t=None, is_periodicity_a=None, is_agsf_transfer=False, max_wavenumber_transfer=None, Rsbo_enforced_transfer=None, logger_name='Pyleecan.Force', init_dict=None, init_str=None)

Bases: pyleecan.Classes.Force.Force

Force Maxwell tensor model for radial flux machines

VERSION = 1

comp_force(output, axes_dict)

Compute the air-gap surface force based on Maxwell Tensor (MT).

Parameters

• self (ForceMT) – A ForceMT object

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

• axes_dict ({Data}) – Dict of axes used for force calculation

Returns

out_dict –

Dict containing the following quantities:

AGSF_rndarray

Airgap radial Maxwell stress (Nt,Na,Nz) [N/m²]

AGSF_tndarray

Airgap tangential Maxwell stress (Nt,Na,Nz) [N/m²]

AGSF_zndarray

Airgap axial Maxwell stress (Nt,Na,Nz) [N/m²]

Return type

dict

comp_force_nodal(output)

Compute the nodal air-gap surface force based on Maxwell Tensor (MT).

Parameters

• self (ForceMT) – A ForceMT object

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

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.
