Abstract
The invention relates to a drive system () with electromagnetic energy transfer. The system () comprises a track () comprising a plurality of stators (), each stator () having at least one winding adapted to generate a magnetic field having a fundamental harmonic () and at least one further harmonic () when fed with an varying current, and a movable element () comprising a primary magnetic element () adapted to receive said fundamental harmonic () to drive said movable element () along said track. The system () is characterized in that said movable element () further comprises a secondary magnetic element (-) adapted to receive said at least one further harmonic () to generate power onboard of said movable element (). The invention also relates to a linear fractional slot synchronous machine and a rotational synchronous machine.
