Permanent magnet rotor in a rotating electrical machine

摘要

A rotor (2) of a rotating electrical machine includes a rotor iron core (20), a plurality of duct members (22), a plurality of permanent magnets (23), and a plurality of through holes. The rotor iron core (20) comprises a plurality of iron core blocks (21) and a plurality of duct members (22). Each of the duct members (22) is disposed between two adjacent iron core blocks (21). Each iron core block (21) includes a circular duct plate comprising a plurality of radial duct pieces disposed in said circular duct plate. The plurality of permanent magnets (23) are disposed in each of the plurality of iron core blocks (21). The plurality of through holes are disposed in duct plates and iron core blocks (21) to hold the plurality of permanent magnets (23).
