That's a pretty cool inductive motor hack. Personally, my favorite esoteric motor has to be the wobble motor built using electropermanent magnets (essentially, programmable permanent magnets):

Do you know of any other "cool" motor hacks?
- coryrc 16y agoBrusa has an induction motor with magnets embedded in the rotor. At high torque, the induction overrides the permanent magnets. At lighter loads, the permanent field dominates and turns it into a synchronous motor. http://www.diyelectriccar.com/forums/showthread.php/evdl-synchronous-induction-hybrid-motori-5938.html http://www.diyelectriccar.com/forums/showthread.php/evdl-syn...
- kwantam 16y agoAnother friend of mine from grad school did his thesis on something like this. http://dspace.mit.edu/handle/1721.1/18013 http://dspace.mit.edu/handle/1721.1/18013 "We propose a novel variation of a doubly-fed induction generator which aims to improve power density and simplify construction. Our design is a doubly-fed, dual-rotor, axial-flux, permanent-magnet machine." The magnets for that thing were truly scary. Every once in a while I gave him a hand with the assembly and it took three or more of us to safely install each magnet in the rotor.
