    Abstract: The object of the invention is a permanent-magnet synchronous machine with a stator (14) and a rotor (12) located at the distance of the air gap (d1) 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 (12) for creating a magnetic flux (?) which is closed via the stator (14), the air gap (d1), and the rotor (12). According to the invention, the relation H = (10 * e - d) * µr applies between the thickness of the permanent magnet and the maximum value of eccentricity e. In the relation, d is the dimensioning value of the air gap and µr is the relative permeability of the permanent magnet.

    Abstract translation: 本发明的目的是一种具有定子（14）和转子（12）的永磁同步电机，该定子位于离定子的气隙（d1）的距离处。 转子以旋转装置支撑在轴上，并且已经确定了定子和转子之间的偏心率的最大值。 该值高于气隙的十分之一。 同步电机的磁化布置有安装在转子（12）中的永磁体，用于产生通过定子（14），气隙（d1）和转子（12）封闭的磁通量（α）。 根据本发明，在永磁体的厚度和偏心率e的最大值之间应用关系H =（10 * e-d）*μr。 在关系中，d是气隙的尺寸值，μr是永磁体的相对磁导率。

    Abstract: The object of the invention is a cooling arrangement for an electrical machine in which a main magnetic field affects the stator and the rotor. In the arrangement, an auxiliary rotor (16, 16') is fitted onto the same shaft (8) with the rotor (6) of the machine and arranged to rotate in relation to the stator (4) and drive shaft (8) of the electrical machine. The number of poles in the auxiliary rotor (16, 16') is substantially smaller than the number of poles in the electrical machine, and a subharmonic magnetic field induced on the stator (6) of the electrical machine is arranged to rotate the auxiliary rotor (16, 16') and a fan (20) arranged to it.

    Abstract: 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.
