The aim of the invention is to produce sheet steel bodies for electrical rotating machines consisting of a base body, a rotor shaft and a laminated rotor body having permanent magnet excitations and coils which are arranged in grooves; said machines should substantially minimise vibration moments and noise emissions. The sheet steel body has a number of grooves which can be deduced from the formula N = 2p•q• +/- 1. According to the invention, one side of a coil is divided up between two adjacent grooves. Said grooves are thus only half filled. Preferably, the magnetic pole construction consists of at least two permanent magnets (1) being axially arranged one behind the other, being off-set from one another in the magnetic groove (3) and being fixed by means of an intermediate component (2). In additional embodiments, the circumference of the arrangement of said permanent magnets (1) is asymmetric by virtue of a reduced pole pitch when said permanent magnets (1) are arranged in a radial or tangential manner. |
