  They might be referring to something like Chorus Motors[0]. I don't know anything about electric motors, but Chorus has been around since the 90s and make similar sounding claims. I'll quote their technology summary[0] "The Chorus Star concept utilizes concentrated, high phase order windings which allows the beneficial use of harmonics (temporal, spatial, and overload). Consequently, a Chorus machine can achieve much higher torque densities than a traditional 3 phase motor, but with no cost penalty. Chorus Star machines are superior to three-phase machines as well as permanent-magnet machines". They make (or are trying to make) a nose-gear mounted assembly for airplanes so you can drive a 737 around with just the APU running - not using the main engines[1]. Also they let pilots pull back from the gate without waiting for a tug on the ground. The claim is that their motor allows them to fit enough torque into the nose wheel to do the job, whereas a conventional motor couldn't do it.
