    Abstract: The present invention relates to an electric motor and a method for manufacturing an electric motor. The electric motor comprises a stator (1), a rotor (2) and an air gap (21) between them. The stator comprises slots (16) and conductors fitted into the slots. The rotor comprises permanent magnets (3, 4) of homogeneous thickness placed consecutively on the rim (5) in the direction of the movement of rotation, which consecutive permanent magnets abut the air gap, and the magnetic poles of which consecutive permanent magnets are fitted in opposite directions with respect to the air gap. The edge line of at least one permanent magnet divides into two sides, asymmetrical to each other with respect to the normal (20) of the center line x (5) that passes through the geometric center point (11) of the permanent magnet.

    Abstract: The invention relates to an arrangement and a method for damping vibration in an electric machine (1). The electric machine has a stator (2) and a rotor (3) with an air gap (4) fitted between them. The stator has a magnetizing winding (5) for generating a temporally variable magnetic field in the said air gap (4) between stator and rotor. The stator is rigidly secured to the machine frame (6) via at least two different mounting points (7, 7', 7''). Fitted in the space (8) between the said mounting points, between the stator and the machine frame, is a damper (9) for damping deflection vibration of the stator (2).
