pyleecan.Classes.LossModelMagnet module¶
Method code available at https://github.com/Eomys/pyleecan/tree/master/pyleecan/Methods/Loss/LossModelMagnet
- class LossModelMagnet(name='', group='', is_show_fig=False, coeff_dict=None, init_dict=None, init_str=None)[source]¶
Bases:
LossModelMagnet Loss Model Class
- VERSION = 1¶
- comp_loss()¶
Calculate eddy-current losses in rotor permanent magnets assuming power density is given by (cf. https://www.femm.info/wiki/SPMLoss):
Pmag = Jm^2/sigma_m with Jm = -sigma_m*1j*2pi*f*Az + Jc where Jc=<Jm> on the magnet surface
- Parameters:
self (LossModelMagnet) – a LossModelMagnet object
- Returns:
Pmagnet_density (ndarray) – Magnet loss density function of frequency and elements [W/m3]
freqs (ndarray) – frequency vector [Hz]
- 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.
