Abstract
A dynamoelectric machine having a permanent magnet rotor construction which contains the permanent magnets while inhibiting flux leakage. The invention further permits rapid, substantially conventional manufacturing techniques to be employed in the formation of rotor laminations used to build the rotors. Flux leakage and formation of reluctance components are inhibited either within the individual rotor laminations or along the length of the rotor by interleaving rotor lamination of different types. The rotor may further be constructed to absorb vibrations within the rotor core and insulate the rotor shaft. The rotor may be still further be constructed for counterbalancing the unbalance of a shaft on which the rotor is mounted.
