Abstract: A protection arrangement of an electric machine which includes a plurality of solid elements layered one after another between a terminal box and a stator of the electric machine. Each of the solid elements includes a cable hole, and the cable holes are arranged to at least partially overlap with each other in order to have a cable channel of the successive cable holes through the solid elements. At least a part of the solid elements are adjustable in a radial direction of the cable channel for making a diameter of the cable channel equal to or smaller than a diameter of the electric cable input in the cable channel in response to adjustment in the radial direction. The protection arrangement comprises a locking mechanism which immobilizes the at least part of solid elements.

Abstract: An end structure for a rotor of an electric machine is attachable to an end of the rotor. The end structure includes a ring arrangement, a rotational axis of which is parallel to that of the stacked rotor, and at least one reinforcing structure at least partly within the ring arrangement. A value of a tensile strength of the at least one reinforcing structure is higher than that of the ring arrangement.

Abstract: A stack of a rotor comprises a plurality of stack elements which include material of first magnetic conductance. The rotor includes sectorial sections distributed round a rotational axis of the rotor. Each of the stack elements has an aperture of second magnetic conductance in each of the sectorial sections. Outer ends of the apertures are located at a rim of the stack elements or at a bridge of the rim. The apertures form channels through the stack in a direction of a rotational axis of the rotor. At least two of the apertures of a common channel of the channels have the outer ends at different radial distances from the rotational axis of the rotor.

Abstract: The invention relates to a rotor for a synchronous reluctance electric machine. It includes a stack of consecutive magnetically conductive core elements; each core element includes at least two adjacent sectorial sections with flux barriers and a central area surrounding the rotational axis. A binding structure includes core end plates which form together with interconnection casts a unitary casted structure. The interconnection casts are casted into channels extending through the stack and which are located in an area defined by the flux barriers of the adjacent sectorial sections and the central area of each core element.
