Abstract

The aim of the invention is to produce an electric machine with very low iron loss, close to zero, for use in particular as a wind generator, lift drive or motors in electric vehicles. The rotating electric machine in a number of variants comprises, in one variant, a rotatably mounted winding body (1), preferably as a cylindrical winding (1) without sheet metal inserts between two tubes (2, 3), an inner tube (2) and an outer tube (3). The inner tube (2) and the outer tube (3) are mechanically connected and fixed together. The inner tube (2) comprises on or in the outer circumference, permanent magnets (4) as a field generators. An air gap (δ2) is formed between the permanent magnets (4) of the inner tube (2) and the winding (1) and an air gap (δ1) is formed between the winding (1) and the outer tube (3). A ceramic support (10) preferably in the form of a ceramic tube (10) with a continuous insertion gap (11) is arranged within the winding (1), the insertion gap (11) can be closed by a ceramic rod (12) or a plastic element (12).
