| 摘要 | A new and useful electrical machine includes a stator including a stator winding and a primary transformer coil. A rotor is operatively connected to rotate relative to the stator, wherein the rotor includes a plurality of embedded permanent magnets. An excitation coil is wound on the rotor and is operatively connected to form a rotating transformer with the primary transformer coil. An inverter/active rectifier component is operatively connected to the stator winding and the primary transformer coil to control the stator winding based on excitation in the stator winding from the excitation coil and permanent magnets. | ||
