Abstract:
A rotor system for a downhole motor includes at least one permanent magnet rotor section, and at least one squirrel cage rotor section. The permanent magnet rotor section and the squirrel cage rotor section are joined in series by a connection. In one example the connection includes a male self lock taper on one rotor, and a corresponding female self lock taper on the other rotor.
