1. A rotating electric machine comprising:
- a stator and windings inserted in slots in the stator, and a rotor having a central axis and poles in the form of pole pieces with solenoid windings and forming solenoids, the poles being separated by pole gaps therebetween and coil supports disposed in said pole gaps in order to support the solenoid windings, wherein the coil supports are arranged in pairs and shaped so that each supports in a radial direction only a part of the solenoid windings of two adjacent poles, and the two coil supports in a pair are arranged axially and radially displaced in relation to each other to allow a cooling gas to flow between the coil supports.

Abstract
The invention relates to a rotating electric machine comprising a stator (4) provided with windings drawn through slots in the stator, and a rotor (1) having a central axis (2) and poles (5, 6) in the form of pole pieces (8, 9) provided with windings and forming solenoids, pole gaps (13) being arranged between the poles. The machine also comprises coil supports (15, 16) in said pole gaps in order to support the solenoid windings (10, 11). It is characterized in that the coil supports (15, 16) are arranged in pairs and that each coil supports (15, 16) is shaped so that it supports only a part of the solenoid windings (10, 11) of the two adjacent poles (5, 6).
