It's fundamentally not different as compared to a normal AC induction motor, but they've split the inducer apart from the rotor coil.
The "transmitter" is just a standard split transformer. As I wrote in my previous post, this design is not new and used to be used extensively as a variant of an AC motor that could have easily variable speed/torque while on a fixed frequency. It's also still used extensively in AC generators (alternators), similar to the way it works in a car alternator, but rather than a set of slip rings which have mechanical wear, they use an exciter field to produce DC voltage in the rotor.
