摘要： An electric rotary machine is provided with a stator having a stator core of laminated iron plates with a given lamination thickness in an axial direction of the machine and a stator winding wound around the core and a rotor rotatably disposed inside the stator, having a rotor core and a rotor winding. The axial length of the stator core is selected with respect to that of the rotor core in such a way that, when the rotor is thermally extended, the end of the rotor core never extends beyond the end of the stator core. With such a constructional arrangement, there is eliminated an excessive temperature rise at the ends of the stator core, and prevented an insulation deterioration of the stator winding and the burning of the stator core.

摘要： A stator for an electric rotary machine adopting a so called gap winding system in which the stator winding is arranged on the smooth inner surface of the stator core. The winding strand groups arranged on the inner surface of the annular stator core are fixedly secured to cooling pipes formed in a cylindrical frame, so that the cooling pipes support the winding strand groups thereby to facilitate transportation and assemblage of the stator winding on the one hand and to provide a sufficiently rugged stator winding to withstand the mechanical stress due to vibrations or electrical short-circuiting which are caused during the running of the electric rotary machine.

摘要： When an induction motor is speed-controlled with a variable frequency power supply including thyristor inverters, operating loss due to harmonics components is increased in a rotor of the induction motor. In order to diverge additional operating loss into an appreciable depth of the rotor to thereby suppress the increase in the operating loss, the rotor comprises a cylindrical member having a circumferential resistivity which is larger than axial and radial resistivities and circumferential permeability which is smaller than axial and radial permeabilities, and a core disposed in the cylindrical member and having an axial permeability which is smaller than circumferential and radial permeabilities.
