HOUSING STRUCTURE FOR DYNAMOELECTRIC MACHINE

摘要

The invention is directed to a base and cover arrangement for an electric machine. The cover is insulated against structure-borne sound and the machine with its base and cover arrangement is configured of elements which can be assembled by the building block principle. The stator of the machine includes pressure plates, tightening devices and the lamination stack. The base and cover arrangement includes a base structure and a cover including side members and a central upper cap. This central upper cap covers a cut-out which is provided in the end-face walls of the side members and which encompasses the shaft of the machine, permitting the stator and the rotor to be lifted out upwardly. The rotor rests in pedestal-type bearings which are also mounted on the base structure. The cover side members as well as the central upper cap are made in different configurations so as to be suited for different types of protection.
