Electric machine
First Claim
1. An electric machine comprising:
- an arched stator and a cylindrical rotor fitted inside the arched stator and in which flux flows in the radial direction between the stator and the rotor as in the case of a permanent-magnet radial-flux synchronous electric machine,wherein the stator of the machine comprises stator segments, andthe stator segments are arranged to be physically separate from each other so that the stator comprises stator segments arched according to the radius of the rotor and working electromagnetically independently like a linear machine, each stator segment having a stator core and a winding separate from the other stator segments, the windings being arranged to fill a smaller portion of each winding slot formed in edge portions of each stator than slots in a middle portion of the respective stator segment, andan overhead supporting frame structure separate from the stator cores comprising several longitudinal ribs and parts between the longitudinal ribs.

Abstract
An electric machine which has an arched stator and a cylindrical rotor fitted inside it and in which the flux flows in the radial direction between the stator and the rotor as in a permanent-magnet radial-flux synchronous electric machine, and in which the stator of the machine consists of stator segments (2), each of which has an independent stator core and winding, and the stator segments are arranged to be physically separate from each other so that the stator consists of stator segments arched according to the radius of the rotor and working electromagnetically independently like a linear machine, each stator segment having a stator core and a winding separate from the other stator segments, and that it comprises an overhead supporting frame structure separate from the stator cores and consisting of several longitudinal ribs (41) and parts (42) between them.
