Abstract
The utility model discloses a DC motor rotor used for a decorative ceiling fan. The rotor includes an annular iron cover. An annular permanent magnetic ring which is integratedly processed by a permanent magnetic material is arranged inside the annular iron cover. The permanent magnetic ring is bonded with an inner wall of the annular iron cover via special-purpose adhesive. The permanent magnetic ring is provided with mounting holes which are fixed on a housing of a motor, and are used to provide convenience for bonding the permanent magnetic ring and the annular iron cover which are connected together. The mounting holes are arranged on the permanent magnetic ring with an interval of 90 degrees of a same concentric circle. In the magnetizing process, the permanent magnetic ring processed by the nylon magnet is exerted with an axial direction or a radial direction external magnetic field, so a magnet with a high magnetic performance can be obtained. A processed product has the advantages of precise size, light weight, thin wall, and complicated shape. Besides, the magnetic performance is stable, so the processed product can be bonded with other metal parts. The adopted nylon permanent magnetic ring can not be smashed caused by the improper installation and can not be begrimed with debris like a neodymium-iron-boron magnet.

The utility model content
The utility model has the advantages that that a kind of simple in structure, installation and processing is provided is convenient, the circular magnet ring that permanent magnet is formed in one can effectively improve the running efficiency of direct current machine and guarantee the rotor DC machine that is used to decorate ceiling fan of its smoothness of operation.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of rotor DC machine that is used to decorate ceiling fan, comprise an annular iron cover (1), it is characterized in that: in annular iron cover (1), be provided with the permanent-magnetic clamp (2) that adopts the permanent-magnet materials one to be processed into annular, be adhered to one by glue between permanent-magnetic clamp (2) and the annular iron cover (1).
Described permanent-magnetic clamp (2) is provided with the permanent-magnetic clamp (2) of being convenient to be adhered to one and annular iron cover (1) and is fixed in installing hole (3) on the motor housing.
Described permanent-magnetic clamp (2) adopts the machine-shaping of nylon magnetic material one.
Described permanent-magnetic clamp (2) lateral wall is provided with the installation tapering of being convenient to annular iron cover (1) assembling.
The tangent value tg α of described installation conicity angles alpha equals 0.1.
The beneficial effects of the utility model are:
When the utility model used, annular iron cover surrounded permanent-magnetic clamp, and is bonding by glue between the two, the iron cover is an annulus, be easy to processing, permanent-magnetic clamp adopts nylon magnetic to be processed into integrated ring body, is convenient to be fixed on annular iron cover and the motor housing; Adopt the permanent-magnetic clamp of nylon magnetic machine-shaping simultaneously, when magnet ring is magnetized, though the magnetic force of injection moulding magnetic is lower slightly than sintering magnetic (producing magnetic behind the general magnet sintering), but it has, and size is accurate, in light weight, wall thin, the strong point of complex contour, annotate magnetic after the machine-shaping as required, and magnetic property is stable, can be with other metal parts (iron cover) molding bonded; And injection moulding magnetic is in forming process, as it being applied axially or radially external magnetic field, then can obtain the higher magnet of magnetic property; Adopt the nylon permanent-magnetic clamp in addition, can not be infected with chip because the improper meeting of installation is cracked as the Ru-Fe-Mn magnet; During assembling, the permanent-magnetic clamp outer wall be provided with circumferential equally distributed reinforcement, be used to thicken the outer wall at magnet ring installing hole place on the one hand, on the other hand pretension fixedly permanent-magnetic clamp put in annular iron, the permanent-magnetic clamp lateral wall is provided with the installation tapering of being convenient to the assembling of annular iron cover simultaneously, and is convenient for assembly, and adopts installing hole to pass from permanent-magnetic clamp and annular iron inner room, reduced in order to guarantee the fixing with one heart optional feature that needs, reduced motor volume; With when motor housing is connected, attachment screw passes installing hole after passing the connecting hole of motor housing, is fixed on an other side of housing then, so just can be connected together external rotor and housing easily.
