    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).

    Abstract: The invention relates to a power supply apparatus and also to a power supply arrangement. The power supply apparatus comprises an interface to the load. The power supply apparatus also comprises at least one controllable solid-state switch, for supplying power between the aforementioned load and the power supply apparatus. The power supply apparatus comprises a controller, which is fitted to control the at least one controllable solid-state switch at the selected switching frequency. The switching frequency is selected such that the noise of the load corresponding to the selected switching frequency meets the selection criterion.

    Abstract: A brake includes a frame part; an armature part supported by the frame part in a manner that allows movement; an electromagnet for opening the brake; and also a damping arrangement for damping the noise of the brake. The damping arrangement is made to be conductive to magnetic flux, and the damping arrangement is fitted on the pathway of the magnetic flux of the electromagnet of the brake.

    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.
