Abstract (en)
[origin: WO2012052202A2] A balanced rotor and a method for balancing a rotor for a rotary machine, such as for example an electric motor, are described. The rotor (1) has at least one disc-shaped rotor body (9), which has magnetic elements (13) in the region of an outer circumference (11). A plurality of off-centre clearances (21) are also formed in the rotor body (9). In order to balance the rotor body (9), a rivet (23), for example in the form of a blind rivet or a Rivscrew® rivet, may be introduced and pressed into one or more of these clearances (41). The rivet (23) is thereby introduced directly into the rotor body (9). There is no need for an additional annular balancing disc. This makes simple, low-cost and reliable balancing of the rotor possible.
