opmcoils.panels.PCBPanel

class opmcoils.panels.PCBPanel(pcb_folder=None, half_names=None, standoff=None, rearrange=False, panel_dict=None)

Attributes:

length

The total length of the panel.

Methods

adjust_standoff(standoff)	Adjust the standoff.
build_chains()	Link PCBs into continuous loops.
magnetic_field(target_points, current)	Calculate total magnetic field from panel.
plot([target_points, current, pl, show])	Plot the PCBs.
plot_profile(current[, profile_dir, ...])	Plot line profile for panel.
resistance([cu_oz, trace_width])	The coil resistance.

to_dict

__init__(pcb_folder=None, half_names=None, standoff=None, rearrange=False, panel_dict=None)

A Panel is a collection of PCBs used to null one field component.

Parameters:

pcb_folderstr

The path to the kicad folder with the PCB design.

half_nameslist of str

The names of the halves used for folder naming. E.g., [‘top’, ‘bott’]

standofffloat

The standoff between the two biplanar PCBs. Typically, this is equal to the length of the PCBs, i.e., 1.4 m.

Attributes:

pcbsdict of PCB

keys of dictionary can be ‘left_top’, ‘left_bott’, ‘right_top’, ‘right_bott’ etc.

Methods

__init__([pcb_folder, half_names, standoff, ...])	A Panel is a collection of PCBs used to null one field component.
adjust_standoff(standoff)	Adjust the standoff.
build_chains()	Link PCBs into continuous loops.
magnetic_field(target_points, current)	Calculate total magnetic field from panel.
plot([target_points, current, pl, show])	Plot the PCBs.
plot_profile(current[, profile_dir, ...])	Plot line profile for panel.
resistance([cu_oz, trace_width])	The coil resistance.

axAxes

matplotlib axes on which to create the plot

resistance(cu_oz=2, trace_width=5)

The coil resistance.
