Abstract

The invention discloses a high-temperature, high-speed permanent magnet motor rotor structure, which includes a main shaft. Support shafts are arranged on both sides of the main shaft. The surface of the support shaft is covered with roller bearings. The front surface of the support shaft is The outer side of the keyway is provided with a keyway, and the inner cavity of the keyway is provided with a flat key. A chute, the inner chamber of the chute is slidably connected with a slider. The present invention can disassemble the rotor iron core through the combination of rotating thread, movable plate, fixed rod, sliding rod, chute, sliding block, fixed block and through hole, so that the use effect of the main shaft is better, and the main shaft is solved. The rotor core on the surface is damaged during long-term use, and the rotor core cannot be disassembled, resulting in the problem that the main shaft and the rotor core are abandoned together, which avoids the economic loss of the user.

Description

technical field [0001] The invention relates to the technical field of motor rotors, in particular to a high-temperature, high-speed permanent magnet motor rotor structure. Background technique [0002] Motor commonly known as "motor" refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque. As a power source for electrical appliances or various machines, its main function is to use mechanical energy. Converted into electrical energy, the most commonly used at present is to use heat energy, water energy, etc. to drive the rotor of the generator to generate electricity. [0003] A motor is composed of a large number of parts, and the rotor structure is one of the most important ones. However, the existing rotor structure on the market is difficult to disassemble the main shaft and the rotor core, so the rotor core on the surface of the ...
