description A rotor of an induction motor comprising a rotary shaft (6), a cylindrical rotor core (7) fixedly secured on the rotary shaft, a conductive cover (8) fixed on the outer circumferential surface of the rotor core, the conductive cover being formed of a composite material of magnetic material (12) and electrically highly conductive material (13) to have a circumferential permeability smaller than a radial permeability, and a magnetic skin (9) made of a magnetic material and provided on the outer circumferential surface of the conductive cover (8), the magnetic skin having a circumferential permeability ( mu ' theta ) and an electrical conductivity ( rho ') which are set to be larger than the circumferential permeability ( mu theta ) and an electrical resistivity ( rho ) of the conductive cover, respectively, whereby a loss due to a spatial higher harmonics magnetic flux of higher order generated by a pulsating magnetic flux ( phi S) at slots in a stator (1) of induction motor can be prevented.
