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.

摘要： A gap winding type dynamo-electric machine, in which armature windings are supported in a gap between a rotor and a slotless slator and along the inner periphery of the stator by supporting means carried by the stator such that they are capable of displacement relative to the stator in the circumferential direction or in both circumferential and axial directions, whereby deformation of the armature windings or damage to their insulating layer due to inflow of short-circuit current or sudden change of load is prevented.
