motor elétrico rotativo, especialmente motor assincrônico com dupla alimentação, na faixa de desempenho entre 20 mva e mais do que 500 mva

摘要

A rotating electric machine includes a rotor configured to rotate about an axis. The rotor includes a rotor laminate stack having layered laminations pressed in an axial direction to form a composite, the rotor laminate stack being radially divided into an inner mechanical region and an outer electrical region. A rotor winding is disposed in the electrical region of the rotor laminate stack. A stator concentrically surrounds the rotor. A press plate is configured to press the layered laminations in the axial direction, the press plate being radially divided into a separate inner press plate and a separate outer press plate so as to correspond to the radial division of the rotor laminate stack.
