Asynchronous electric motor rotor mfr. - using short-circuit rods fitting through rotor laminations packet coupled to short-circuit ring at each end

摘要

The rotor has a laminations packet (2) with a short-circuit ring (6) at each side and short-circuit rods (9) fitting through respective openings in the stampings packet (2) arranged in a ring and attached to the short-circuit rings (6) at their ends. The short-circuit rods (9) rods (9) project beyond the short-circuit rings (6) at each end and act as the mechanical fixings for the latter and the rotor laminations packet (2). ADVANTAGE - Simultaneous mechanical and electrical couplings.
