Problems solved by technology

However, the use of glass fiber protective tape is cumbersome in the production and assembly process of the rotor, which is time-consuming and laborious, and increases the production cost; while the use of steel sleeve structure will cause eddy current loss, reduce the efficiency of the motor, and affect the performance of the motor. The effects of both are not very good

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the description of the drawings and specific embodiments.

[0019] Such as Figure 1 to Figure 4 As shown, a permanent magnet servo motor rotor includes a rotating shaft iron core integral component 1 and a magnetic ring, the magnetic ring is a sintered NdFeB magnetic ring 2, and the sintered NdFeB magnetic ring 2 is arranged on the rotating shaft iron On the core integrated component 1, the rotating shaft and the iron core adopt an integral structure to form the rotating shaft and iron core integrated component 1, which can be used as a supporting part to transmit motion, or as a part of the magnetic circuit.

[0020] Such as Figure 1 to Figure 4 As shown, the outer peripheral surface 12 of the integral component of the rotating shaft iron core 1 is uniformly coated with anaerobic adhesive.

[0021] Such as Figure 1 to Figure 4 As shown, the end face 11 of the rotating shaft iron core integr...

Abstract

The invention provides a permanent magnet servo motor rotor. The permanent magnet servo motor rotor includes an integrated member of rotating shaft and iron core, and magnet rings, wherein the magnet rings are arranged on the integrated member of rotating shaft and iron core. The invention also provides a manufacturing method of the permanent magnet servo motor rotor. The permanent magnet servo motor rotor has the advantages that the integrated structure of rotating shaft and iron core is utilized so that the assembling process of the rotor and the iron core can be saved; as glass fibres and other protection sleeves are not added on the outside of the magnetic rings, the assembling relation is simple and the production cost is saved; a steel protective device is not required to add on the outside of each magnetic ring, so that eddy current loss is not generated; only the outside of the integrated member of rotating shaft and iron core is required to be coated with adhesive uniformly, and then the magnetic rings which are not magnetized are put in the integrated member of rotating shaft and iron core, and when the rotor is baked to become solid and reliable in a baking box, the rotor can be magnetized integrally with a desired magnetic field wave form; and the rotor structure enables the air gap to be smaller, so that the utilization rate of permanent magnet can be improved.

Description

technical field [0001] The invention relates to a motor, in particular to a permanent magnet servo motor rotor and a manufacturing method thereof. Background technique [0002] Servo motors are widely used in machine tools and textile industries due to their good speed regulation performance and high precision. The rotor structure of the servo motor is mostly surface-mounted, and the surface-mounted rotor structure is mostly pasted on the surface of the rotor core with magnetic steel and glue, and then fixed with a glass fiber protection tape or steel sleeve outside the magnetic steel to prevent the motor from running at high speed. At this time, due to the centrifugal force, the magnetic steel will loosen or fall off. However, the use of glass fiber protective tape is cumbersome in the manufacturing and assembly process of the rotor, which is time-consuming and laborious, and increases the production cost; while the use of steel sleeve structure will generate eddy current ...
