METHOD FOR SIZING OF A ROTOR, ASSOCIATED ROTOR AND MOTOR-COMPRESSOR

The invention relates to a method for sizing of a rotor, an associated rotor and a motor-compressor. 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. 本发明涉及用于确定转子大小的方法、相关联转子和马达-压缩机组。具有旨在驱动传动线的非贯通轴的用于电机的转子包括包封圆柱形磁性块的两个半轴。磁性块包括至少两个相邻的相同单元，单元构造成防止在传动线的激励频率范围内超阻尼在转子中的传播，传动线的旋转频率范围为超临界的。
