What about double-sided rotors? Do double-sided rotors give you twice the torque and twice the FoM? Congratulations, you’ve made two motors and stuck them together! In certain arrangements (e.g. YASA), there is an advantage (and structural challenges added) vs literally slapping two motors together, from removing the “yoke” of the stator (or rotor backiron, in a double-stator motor), hence the “Yokeless” in Yokeless And Segmented Armature. This can be significant in terms of mass & volume, especially in low pole-count motors where the yoke & backiron have to be thick.
\nThese signals relay more than just what you’ve eaten and when you are full. A new study in mice from researchers at Stanford Medicine and the Palo Alto, California-based Arc Institute has identified a critical link between the bacteria that live in your gut and the cognitive decline that often occurs with aging.
