<p>An exemplary permanent-magnet synchronous machine is disclosed with a stator and a rotor located at the distance of the air gap (delta1) from the stator. The rotor is supported on the shaft in a rotating arrangement, and a maximum value has been determined for the eccentricity between the stator and the rotor. The value is higher than one-tenth of the air gap. The magnetization of the synchronous machine is arranged with permanent magnets fitted in the rotor for creating a magnetic flux (phi) which is closed via the stator, the air gap (delta1), and the rotor. A relation H>=(10*epsilon-delta)*mur applies between the thickness of the permanent magnet and the maximum value of eccentricity epsilon, wherein delta is the dimensioning value of the air gap and mur is the relative permeability of the permanent magnet.</p> |
