Abstract: An interior permanent magnet rotor restrains demagnetization of permanent magnets embedded in a core. Each permanent magnet is formed by joining a first portion and a second portion at a connection. The first and second portions extend from the outer side toward the inner side in the radial direction of the core. The outer end faces of the first and second portions in the radial direction of the core extend in an orientation direction as viewed in section perpendicular to the axial direction. The outside diameter of the core gradually increases from the boundaries between a single magnetic pole and magnetic poles adjoining the single magnetic pole toward the middle of the single magnetic pole in the circumferential direction of the core.

Abstract: A rotating electric machine has a semiconductor magnetic sensor and a cylindrical housing with a cylinder part, which is made of a soft magnetic material, positioned closer to the semiconductor magnetic sensor relative to a back yoke of a stator core. The semiconductor magnetic sensor is positioned away from the cylindrical housing so that a shortest distance between a center of the semiconductor magnetic sensor and the cylindrical housing is equal to or greater than 50 times of a sum of a first space distance and a second space distance. With such an arrangement, a leak magnetic field generated by magnetic poles that leaks in an axial direction is prevented from disturbing the semiconductor magnetic sensor. Thus, a rotation position detection accuracy of the semiconductor magnetic sensor is improved.

Abstract: A baffle train for turbine generator air baffles independently aligns axial position of the composite air baffle along a stator core bore axial slot. Air baffle sectors that form the composite air baffle are coupled to baffle blocks of the baffle train. The baffle blocks are positioned axially along at least one axial spacer rod corresponding to the desired position of the composite air baffle within the stator bore. The baffle blocks are locked into position by a locking engagement member. Wedge blocks are axially spaced on a reciprocating wedge block rod within the stator slot below the baffle blocks. A biasing element, such as arched leaf spring, tensions the baffle block radially inwardly toward the stator bore when the wedge blocks are reciprocated below the baffle blocks.

Abstract: In a method an inner segment is first pre-assembled on each of a number of outer segments by at least one fixing element, so as to produce a plurality of segment modules having each a predetermined air gap between the inner segment and the outer segment. The inner segments and the outer segments are assigned to the rotor or stator of the electrical machine. The inner segments of the plurality of segment modules are fastened to an inner assembly device (for example a hub). The outer segments of the plurality of segment modules are fastened to an outer assembly device (for example a supporting structure). Finally, the fixing elements between the inner segments and the outer segments are removed.
