摘要： An electric rotating machine including a rotor (50) having a spider arm (1) which is fixedly mounted on a substantially vertical shaft (11) and has arms (14) extending radially outwardly from the shaft (11), and an annular rotor rim (2) fixedly mounted on distal ends of the arms (14) of the spider arm (1). The laminated core (3) is fixedly mounted on an outer periphery of the rotor rim (2), and is composed of a plurality of fan-shaped thin core plates (31) of steel laminated and arranged in an annular shape. Slot grooves (32) are formed in an outer periphery of the core plates. The rotor rim (2) is composed of laminated rim members (21) each made of an annular thick steel plate, and rim engaging grooves are formed in an outer periphery of the rim member at equal intervals. The core plate has core engaging grooves (33) opposed to the rim engaging grooves (26), respectively, in such a manner that the number of complete core engaging grooves is two. An axially-extending connecting key (8) is fitted in each mating pair of core engaging groove and rim engaging groove to fix the laminated core (3) to the rotor rim (2).

摘要： A method of assembling a wound rotor of an adjustable speed electric rotating machine comprises the step of laying down a rotor body (10) on its side into a pit (1a) in a power house of a hydroelectric power plant, but protruding its circumference top surface from the pit (1a) to facilitate working personnels to carry out field coil assembling operations from the foundation of the power house. Thus, an increase in height of the power house is limited to the sum of the axial length of the assembled wound rotor (15) and the height of the lifting jig of a crane (50).
