Abstract

PURPOSE:To prevent the deformation with time and thermal deformation of a rotor and enhance the form stability thereof by fastening, to a rotor shaft, a fixing nuclear body having an outer diameter nearly equal to that of a rotor outer periphery and a rigidity higher than that of an insulator rotor-molding material filling in the surroundings of said nuclear body. CONSTITUTION:A fixing nuclear body 2 having an outer diameter nearly equal to that of a rotor outer periphery and a rigidity higher than that of a rotor- molding material 4 is fastened to a rotor shaft 1. A coil row 3 is integrally molded into a given cylindrical shape by said rotor-molding material 4 and, particularly in a molding material disc part 4a, is fastened to the rotor shaft 1 via the rotor molding material 4 and the fixing nuclear body 2. In this manner, a geometrical stability is enhanced, a dimensional accuracy directly after molding can be secured, and the lowering with time of a geometrical accuracy can be prevented even if an apparatus is left at high temperature and humidity or subjected to high and low temperature impact.
