Abstract

The invention mainly aims to provide a rotor structure, a motor and a compressor. The rotor structure comprises a rotor iron core and a plurality of permanent magnets arranged on the rotor iron core so as to form a plurality of magnetic poles on the rotor iron core, wherein the plurality of magnetic poles comprise a plurality of N poles and a plurality of S poles which are alternately arranged along the circumferential direction of the rotor iron core, at least one magnetic pole of the rotor iron core is provided with a magnetic isolation hole, the magnetic isolation hole comprises a first hole body part, a second hole body part and a third hole body part which are communicated with one another, the second hole body part and the third hole body part are respectively arranged at two ends ofthe first hole body part along the direction far away from the axis of the rotor iron core, and in the circumferential direction of the rotor iron core, the second hole body part and the third hole body part protrude out of the first hole body part. By means of the arrangement, the problem that in the prior art, vibration noise of a motor is large is solved.

Description

technical field [0001] The invention relates to the field of motors, in particular to a rotor structure, a motor and a compressor. Background technique [0002] In recent years, with the development of permanent magnet material manufacturing technology and rapid cost reduction, its excellent performance and low price have greatly promoted the development of permanent magnet motor technology. The abundant resources of permanent magnet materials have promoted the research and development of permanent magnet motor technology. [0003] Permanent magnet motors rely on permanent magnets to generate the main magnetic field. Compared with ordinary induction motors, permanent magnet synchronous motors do not require reactive excitation current, and the rotor resistance loss is zero under synchronous operation. Therefore, it has the characteristics of high power factor and high efficiency, and can usually be used to replace induction motors with low power indicators. Its economic and ...
