Method for sizing a rotor with a non-through shaft, associated rotor and motor-compressor set

The rotor for an electrical machine with a non-through shaft intended to drive a transmission line comprises two half-shafts enclosing a cylindrical magnetic mass.The magnetic mass comprises at least two adjacent identical cells, the cells being configured to prevent the propagation of metadamping i...

More Information
Summary:The rotor for an electrical machine with a non-through shaft intended to drive a transmission line comprises two half-shafts enclosing a cylindrical magnetic mass.The magnetic mass comprises at least two adjacent identical cells, the cells being configured to prevent the propagation of metadamping in the rotor over a range of excitation frequencies of the transmission line, the rotation frequency range of the transmission line being hypercritical.
