Abstract An electric machine and corresponding motor‑control method are disclosed. The stator includes windings energized to form stator poles, while the rotor includes rotor windings energized to form interacting rotor poles that generate relative force between the rotor and stator. The rotor is magnetically coupled to the stator to receive a wireless power transfer signal, eliminating the need for mechanical electrical interfaces. A first rotor winding additionally receives a wireless data signal from one or more stator windings to support coordinated control. An active rectifier, rotationally fixed to the rotor and conductively coupled to the first rotor winding, captures electrical energy from the wireless power transfer signal and regulates current flow through the winding by directing the captured energy into it. The associated method includes wirelessly receiving power and data at the rotor, rectifying the received energy, and controlling rotor‑winding current to enable controlled rotor excitation.
