Abstract

The invention relates to an ultrahigh-speed permanent magnet disk motor. The motor comprises a first stator core, a second stator core, a stator winding, an enclosure, a heat dissipation pipeline, a front end cover, a rear end cover, a high-speed rotor and ceramic bearings, wherein the high-speed rotor comprises a high-speed rotor core, permanent magnets, a rotor sheath and a rotor shaft; and thehigh-speed rotor core is installed on the rotor shaft in a sleeving mode, permanent magnet wedge-shaped installing slots are processed in the radial direction to install the permanent magnets, the permanent magnets are installed at the two axial sides of the high-speed rotor core, and the rotor sheath is installed on the high-speed rotor core. The motor has high mechanical strength and is suitablefor ultrahigh-speed running; and moreover, a good heat dissipation system is designed, and the situation that the permanent magnets are demagnetized during ultrahigh-speed running of the disk motor is prevented. The invention not only provides an ultrahigh-speed permanent magnet motor scheme but also discloses a motor assembling method.

Description

Technical field: [0001] The invention relates to the technical field of motors, in particular to an ultra-high-speed permanent disk motor and an assembly method. Background technique: [0002] In recent years, with the advancement of materials and processes, ultra-high-speed motors have been widely used. However, some special applications have strict restrictions on the volume of ultra-high-speed motors. Ultra-high-speed disc motors have the advantages of high power density, small size, short axial length, and good heat dissipation. They are the development direction of special power devices (or power generation devices). . Compared with conventional motors, higher requirements are placed on the mechanical strength of the ultra-high-speed motor rotor, and higher requirements are placed on the cooling of the permanent magnets of the ultra-high-speed motor. [0003] Therefore, the mechanical strength and heat dissipation problems of ultra-high-speed motors are of great signi...
