Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] refer to Figure 1 to Figure 3 The shown NdFeB outer rotor includes an inner magnetic ring 6 and a magnetically conductive ring 5. The inner magnetic ring 6 is formed into a ring-shaped magnetic ring by injection molding of NdFeB. The magnetically conductive ring 5 is tightly matched to the The outer side of the inner magnetic ring 6 forms an outer rotor with an integrated structure.

[0028] In the embodiment, the thickness of the inner magnetic ring 6 is 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm or 15mm, etc., and the thickness of the magnetic permeable ring 5 is 3mm, 4mm, 5mm, etc. , the thickness of the inner magnetic ring 6 and the magnetic conduction ring 5 is determined according to the size of the rotor, the larger the rotor, the thicker the thickness, and in order to better and efficiently utilize the magnetic field of the inner m...

Abstract

The invention relates to a NdFeB outer rotor and a manufacturing method thereof, wherein the NdFeB outer rotor comprises an inner magnetic ring (6) and a magnetic conductive ring (5); the inner magnetic ring (6) is a circular ring structure magnetic ring formed by injection molding of NdFeB; and the magnetic conductive ring (5) and the inner magnetic ring (6) are tightly matched to form an outer rotor with an integral structure. The invention can effectively and fully utilize the magnetic field of the inner magnetic ring, improve the power utilization of the magnetic field, and realize the effect of more energy saving.

Description

technical field [0001] The invention relates to a motor rotor, in particular to a motor outer rotor and a manufacturing method thereof. Background technique [0002] With the requirements of energy saving and environmental protection, brushless DC motors are more and more widely used in household appliances or other fields due to their high efficiency, low noise, and stepless speed regulation. As the main component of the brushless DC motor, the outer rotor is bonded by multiple NdFeB magnetic tiles and the magnetic ring. The reliability of the bonding of the magnetic tiles has the defect of falling off, and the distribution of the magnetic tiles in the magnetic ring is uneven. , can not guarantee the uniform distribution of mounting holes and other defects. Contents of the invention [0003] The object of the present invention is to provide an NdFeB outer rotor and a manufacturing method thereof in order to solve the above-mentioned technical problems in the existing bru...
