摘要： A method is disclosed for fitting a rotor enclosure over at least one assembly of field windings mounted on a rotor core, said method comprising the steps: applying a force to elastically reduce a circumference of the at least one assembly of field windings mounted on the rotor core, where the reduction in circumference is greater than a circumference reduction due to just eliminating clearances between adjacent end-turns of windings; generating a clearance between the field windings and the rotor enclosure due to the application of the force; axially sliding the rotor enclosure over the at least one assembly of field windings while the circumference is reduced, and releasing the force to allow the circumference of the at least one assembly of field windings to expand and cause the enclosure to tightly fit on the at least one assembly of field windings.

摘要： A stator and a method of forming the stator comprises providing a stator frame having a frame plate, and connecting key bars to the frame plate at respective connection points, each of the key bars having a dovetail. The stator and method further includes providing a stator core comprising laminations each having a dovetail slot formed therein. Each dovetail is engaged into a respective dovetail slot so that at least some of the dovetails contact respective laminations at respective contact points. The locations of the contact points are controlled such that a force load transmitted by the contact points is evenly distributed among the contact points to thus minimize the maximum force transmitted. The location of the contact points is controlled such that a key bar stress at the connection points is also minimized.

摘要： A stator comprises a stator frame, a stator core and a spring. The stator core includes at least one lamination having a dovetail slot formed therein. A key bar is connected to the stator frame and includes a dovetail for engaging the dovetail slot. The spring is coupled between a portion of the lamination and the dovetail to provide an electrical ground path between the stator core and the stator frame. The spring includes a leaf spring that has first and second ends which contact the dovetail and a central portion. The central portion is connected to a base portion which contacts the lamination. Alternatively, the spring includes a base portion that contacts the lamination and prongs which project from the base portion and contact the dovetail.

摘要： A stator comprises a stator frame, a plurality of key bars connected to the stator frame and a stator core. Each of the key bars has a dovetail. The stator core is formed by a pre-packaged stator core section including laminations each having a dovetail slot for engaging a respective dovetail. The stator core also includes a manually stacked stator core section including manually stacked laminations each having a dovetail slot for engaging respective dovetails. The cross-sectional area of the dovetail slots in the pre-packaged stator core section is larger than the cross-sectional area of the dovetail slots of the manually stacked stator core section.

摘要： A structural integrity monitoring system includes a structure, at least two vibration monitoring devices mounted to the structure. Each of the at least two vibration monitoring devices outputs a vibration response signal. The structural integrity monitoring system also includes a controller operatively connected to each of the at least two vibration monitoring devices. The controller is configured to calculate a predicted vibration response based upon a vibration mode shape and the vibration response signal. The controller then compares the predicted vibration response against a measured vibration response to detect changes in the structure.
