Patent ID: 6879074

Claim:
Magnetically journalled electrical drive including a magnetically journalled electrical machine with windings inserted in the stator or rotor for the formation of torque and levitation force, a sensor system for determining the rotor positions and an analogue or digital electronic system for the control, regulation, monitoring and feeding of the magnetically journalled machine, with the electrical machine having windings which with appropriate current flow can produce magnetomotive forces (MMFs) or magnetic fields with the pole numbers p 1 and p 2 with p 1 and p 2 satisfying the condition p 1 =p 2 ±2 and p 1 or p 2 representing the pole number of the rotor, characterized in that the electrical machine is equipped for the p 1 and p 2 pole field production or MMF production in the stator with a number n of stator limbs (with concentrated windings), stator teeth (with distributed windings) or stator slots, with the number n not simultaneously representing a whole-numbered multiple of the pole number p 1 and the pole number p 2 .
