Abstract

The invention discloses a modulation ring rotor based on a magnetic shielding principle, belongs to the field of a permanent magnet motor, and aims at solving the problem that the existing modulation ring rotor can not consider both low loss and high mechanical strength. The modulation ring rotor comprises two end rings, n magnetic blocks and n connecting rods, wherein a plurality of through holes are uniformly formed in the end surfaces of the end rings along the periphery direction; a plurality of screw holes are uniformly formed in one end surface of the end rings; the two end rings are arranged in parallel; the screw hole sides of the end rings are arranged back to back; the positions of the through holes in the two end rings are opposite one by one; the n magnetic blocksare arranged between the two end rings; each magnetic block is fixed with the two end rings together through one connecting rod; a cylindrical screw is arranged at each end of a body of each connecting rod; the body of each connecting rod is embedded in the magnetic block; the screws at the two ends of the body of the connecting rod respectively penetrate through the through holes; and each screw is fixedly provided with a nut for clamping the end rings and the magnetic blocks.

Description

technical field [0001] The invention relates to a modulation ring rotor based on the magnetic field shielding principle, and belongs to the field of permanent magnet motors. Background technique [0002] The brushless dual-rotor motor based on the principle of magnetic field modulation has two rotors and shafts with independent rotational speeds, which can realize independent drive of two shafts. It solves the problem of lower operating efficiency, lower reliability and frequent maintenance due to the use of brush slip ring structure in the previous brushed double-rotor motor, as well as serious heating and dynamic balance problems of the rotor with armature winding. Therefore, it has broad application prospects in electric vehicles, wind power generation, torpedo propulsion and other occasions.
