Abstract

The invention relates to the field of electric machines, in particular to a rotor iron core and an electric machine having the same, comprising a rotor body, wherein the rotor body is provided with atleast one magnetic steel groove; The magnetic steel groove is provided with a magnetically conductive elastic member and a non-magnetically conductive elastic member; The surface between the two endsof the magnetic steel groove close to the outer side of the rotor body is an outer wall surface; The surface of the magnetic steel groove corresponding to the outer wall is an inner wall surface, thenon-magnetically conductive elastic member is arranged on the outer wall surface, and the magnetically conductive elastic member is arranged on the inner wall surface. When the rotor core rotates, the magnetically conductive elastic member and the non-magnetically conductive elastic member can change the position of the magnetic steel in the magnetic steel groove, thereby regulating the magneticflux of the rotor core.

Description

technical field [0001] The invention relates to the field of motors, in particular to a rotor core and a motor with the same. Background technique [0002] With the advancement of technology, permanent magnet synchronous motors are used more and more in manufacturing due to their own advantages; the existing permanent magnet motors are fixed due to the permanent magnet magnetomotive force, the main magnetic flux cannot be adjusted according to needs, and the operating range of the motor is narrow. The speed range is limited, and the magnetic flux obtained at low speed is small. Contents of the invention [0003] The purpose of the present invention is to provide a rotor core, which can change the position of the magnetic steel in the magnetic steel groove through the magnetic conductive elastic part and the non-magnetic conductive elastic part when the rotor core rotates, thereby adjusting the magnetic flux of the rotor core. [0004] Another object of the utility model i...
