Abstract:
A magnetically journalled electrical drive comprising a magnetically journalled electrical machine, machine and magnetic bearing windings inserted in at least one of a stator and a rotor for producing torque and a suspension force, and electronic circuitry for control, regulation, monitoring and excitation of the magnetically journalled machine, wherein the magnetically journalled machine is equipped in at least one of the stator and the rotor with a separate one of a single looped winding and a multiple looped winding for producing the torque and the suspension force, at least one of the windings being formed as a concentrated winding with pronounced winding poles, and wherein the one of a single looped winding and a multiple looped winding for producing the torque has a number of pole pairs pM and the one of a single looped winding and a multiple looped winding for producing the suspension force has a number of pole pairs pML=pMÂ±1.
