摘要:
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.
摘要:
Nonlinear elastography systems and methods are provided. The elastography system includes a data acquisition module, such as an imaging device, and associated system control circuitry. The data acquisition module is configured to acquire various data, such as displacement and/or force data, from a material. A nonlinear transfer function is applied to the acquired data to generate information about the material's stiffness. In one implementation, a map representative of the material's stiffness is generated.
