method for assembling a rotor of a hydroelectric bewickelten lathe vertical design and adjustable speed to his location to install.

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).
