Those example motors are way too big for your application, I was intending that they would serve as an example for the pancake motor geometry. I would suggest you look up "Frameless Motors". These motors need to be integrated into a housing but will give you the most flexibility/options when searching for a motor that meets your specifications. You can apply the dimensional technique I started above when comparing different motors. Regarding performance metrics. I would start by identifying your maximum torque requirements over the speed range you need maximum torque. | |

| Apr 28, 2021 at 5:17 | comment | added | Real Magnetics | That is a difficult question to answer. You really have to compare efficiency maps of motors to determine performance differences. Regarding pancake motors I can provide some examples on how they improve efficiency. I know Magnax has a somewhat ingenious design where their stator pole-pieces are wound as solenoids (then grouped together to construct the stator). This is done to reduce end turns, which increases efficiency. I believe that Magnax also uses grain oriented electrical steel in their pole-pieces (typically only used in transformers) which lowers core loss in pole pieces. | |
