Abstract

The invention discloses an ultra-high-speed permanent magnet synchronous motor applied in a high-temperature environment. The motor adopts the internal claw pole stator topology, which is composed of multiple claw pole stator unit modules. The structure is provided with a cavity in the middle of each stator core unit module, and the section of the cavity changes gradually along the axial direction of the rotating shaft. Because of the particularity of the stator core unit module structure, the present invention adopts a soft magnetic composite material (SMC ), SMC is a new type of soft magnetic material manufactured by powder metallurgy technology. The main component is pure iron particles wrapped with insulating materials on the surface. Low, suitable for the special cavity structure of the present invention, the present invention provides an ultra-high-speed permanent magnet motor capable of long-term reliable operation in extreme environments, including a new stator structure type, ring winding structure type, etc., broadening the ultra-high-speed permanent magnet motor Structural types and application fields of magneto.

Description

【Technical field】 [0001] The invention belongs to the technical field of high-speed permanent magnet motors, and in particular relates to an ultra-high-speed permanent magnet synchronous motor applied in a high-temperature environment. 【Background technique】 [0002] High-speed permanent magnet motors have the advantages of high power density, high efficiency, wide speed range and small size, and are widely used in micro gas turbines, centrifugal air compressors, flywheel energy storage, new energy distributed power generation and other fields. [0003] In addition, with the rapid development of national aerospace technology, national defense technology, polar deep sea exploration and other fields, high-speed permanent magnet motors also play a very important role with their excellent characteristics. However, these workplaces require the motor to have the ability to operate reliably for a long time in harsh environments such as high temperature, low temperature or vacuum. ...
