Abstract: A cooling arrangement is disclosed for an electrical machine in which the main cooling air circulation within the machine is arranged using a centrifugal blower in at least one of the ends of the machine, making the main cooling air circulation flow through at least an air space in the machine and the outer surface of the stator. A circulating fan is arranged in the immediate vicinity of the centrifugal fan for the purpose of generating a coil end circulation that circulates air at least in the area of the machine's coil ends.

Abstract: SUMMARY The object of the invention is a rotor for a synchronous reluctance machine which comprises an axis, which is supported by bearings to rotate inside a stator, and to which axis a rotor frame has been attached, and the manufacturing method of the rotor. According to the invention, the frame (12) is made of magnetically non-conductive material, comprising arranged magnetically conductive bar-shaped objects (16,18) which extend through the rotor frame from the outer surface of the magnetic pole of the rotor to the outer surface of the pole and that the whole length of each bar-shaped object (16,18) inside the rotor frame (2) is surrounded by non-magnetic material.

Abstract: Electric machine rotor comprising: an inner rotor element and an outer rotor element positioned more outwards in the radial direction than the inner rotor element, the inner rotor element and the outer rotor element being made of a material of high permeance, and an air gap of low permeance between the inner rotor element and the outer rotor element. The outer rotor element forms a shape-mating pair with the inner rotor element, the inner rotor element and the outer rotor element being shaped in such a way that radial detachment of the outer rotor element from the inner rotor element is prevented.

Abstract: The object of the invention is a rotor for an electrical machine excited by permanent magnets, said rotor comprising a substantially cylindrical magnetic body of the rotor fitted onto the shaft of the electrical machine and a set of permanent magnets used to create a first and a second pole alternately in the circumferential direction, excited in opposite directions. The permanent magnets are fitted into openings arranged within the rotor. The rotor comprises a body part with several segments extending to the outer circumference in the circumferential direction and an outward tapered section remaining between the segments in the radial direction of the rotor. Permanent-magnet pieces are arranged between each section and segment.
