The present invention comprises a pole wheel (13), and as for the method for manufacturing a wind generator or a multi-pole generator in a wind turbine magnetic system (1), the magnet system has a plurality of discrete permanent magnets arranged in a ring form (4, 4 ') at least one magnetic ring (2) and at least one of the magnetic wheel (10 having a pawl wheel housing, the magnetic ring and between 11 (2) and the support (5) for supporting the ring having a) and between the housing and accommodated in the inner peripheral surface of the inner diameter of the temperature is to be expanded to a size larger than the outer diameter of the magnetic wheel 10, the outer diameter or the magnetic ring (2) of the pole wheel housing 11 forming a surface 14 heating the pole wheel housing, and the pawl retracting the wheel housing (11) at least one magnetic ring is cooled to ambient temperature (2) or the magnetic wheel 10 pole wheel housing 11 on and the receiving surface 14 by placing the magnetic wheel 10, or at least one magnetic ring (2) on the connection To form. An object of the present invention is the assembly is simple, so that cost effective and reliable among the magnetic wheel or a magnetic ring and the pole wheel housing provides a solution that represents a highly stable connection. For this purpose, old pole to the wheel housing (11) is heated and / or the magnetic ring (2) or of the magnetic wheel (10) before the position, and / or pole wheel housing (11) before the cooling, at least one the magnetic ring (2) or the outer peripheral surface and / or the receiving of the magnetic wheel 10, the surface 14 is provided with pawl wheel housing 11 is to shrink pole wheel housing 11 and the at least one magnetic ring (2) or the adhesive 15 is provided for forming a connecting portion coupled between the magnetic wheel (10).
