Abstract
A magnetically journalled electrical drive has a magnetically journalled electrical machine with machine and magnetic bearing windings which are inserted in the stator or rotor for the production of torque and the suspension force, and an analog or digital electronic circuitry for the control, regulation, monitoring and excitation of the magnetically journalled machine. The magnetically journalled machine is equipped in the stator or rotor with separate single or multiple looped windings for producing the torque (30, 31, 32, 33) and for producing the suspension force (34, 35, 36, 37), with at least one of the windings being formed as a concentrated winding with pronounced winding poles.
