Summary for: SPM2 < SynRotorBase

Class summary

SPM2 Template for a surface-PM rotor.

Surface-PM rotor geometry with arc magnets.

Supports:

Dimensions:

Rout : airgap-side radius.
Rin : (OPTIONAL) shaft radius (inrunners) or yoke-side radius (outrunner). parsed from hyr if not given.
hyr : (OPTIONAL) rotor yoke thickness. Used if Rin not given.
hpm : magnet thickness
h_pm_edge : (OPTIONAl) magnet thickness at magnet edge. Default : hpm
alpha_pm : PM pitch, as a ratio to the pole pitch. In ]0, 1[.
is_halbach : booleanr, use Halbach array or not.
h_sleeve : retaining sleeve thickness. OPTIONAL. Default 0.
number_of_magnet_segments : (OPTIONAL) Number of circumferential magnet segments. Default 1.

Materials:

rotor_core_material : rotor core material.
magnet_material : magnet material.
rotor_sleeve_material : sleeve material. Only required if h_sleeve > 0.
shaft_material : (OPTIONAL) Shaft material. Only used in inrunner designs. Not giving the shaft material creates a hollow rotor.
polegap_material : (OPTIONAL) Material of polegaps for SPM designs. Defaults to Air. For Halbach-array machines, this is the material of the circumferentially magnetized magnets.

Magnet circuit model:

magnet_circuit_type : (OPTIONAL). “block” (default) or “extruded”, to use axially-segmented magnet model.
magnet_height : magnet segment height, if axially segmented model.

(OPTIONAL) Circular cooling hole dimensions, inrunners only:

rotor_cooling_holes_per_pole : number of cooling holes per pole, inside the rotor core.
rotor_cooling_hole_radius : radius of cooling hole
rotor_cooling_hole_radial_coordinate : distance of cooling hole center from origin
