Abstract
The utility model relates to the technical field of micromotor, in particular to a magnetic plastic magnet ring. The magnetic plastic magnet ring comprises a magnet ring body and at least two arc-shaped magnetic segments, wherein the magnet ring body is an integral structure formed by injection molding of magnetic materials and the magnetic segments are inlaid in the magnet ring body in a uniformly-distributed arrangement with the polarities reversed to each other. A through-hole is disposed in the center of the surface of the magnet ring body and four circular holes are uniformly distributed on the periphery of the through-hole. The magnet ring of the utility model is formed by one-step molding of the magnetic materials, thereby ensuring the concentricity and quality uniformity of the magnet ring, and at least two magnetic segments are inlaid during molding, thereby enabling a multipolar magnetic field for the manufactured magnet ring.
Description
Technical field
The utility model relates to the electrical micro-machine technical field, especially a kind of magnetic plastics magnet ring.
Background technology
Electrical micro-machine has been widely used in fields such as automation, electromechanics now.The multi-pole magnet-ring that in fields such as electrical micro-machine and stepping motor, is widely used uses and is rotor, add outside pass through a pulse current in the coil after, rotor just turns over a fixing angle.
Traditional multi-pole magnet-ring is to use bonding the forming of polylith magnetic section; But when the manufacturing small-sized electrical micro-machine, be difficult to processing, owing to be the splicing of polylith magnetic section, be difficult to the magnetic pole angle is done accurately simultaneously; Be difficult to accomplish that whole magnet ring quality is even during simultaneously owing to splicing; Make that the dynamic balancing of magnet ring is poor, increased the vibration and the noise of motor, influence motor performance.
The utility model content
The technical problem that the utility model will solve is: based on the problems referred to above, angle magnetic plastics magnet ring accurately is provided between a kind of distance between two poles and magnetic pole of simple in structure, polylith magnetic section.
The utility model solves the technical scheme that its technical problem adopted: a kind of magnetic plastics magnet ring; Comprise magnetic ring body and at least two circular arc magnetic sections; Described magnetic ring body is the injection molded integrative-structure of magnetic material, and described magnetic section is embedded in the magnetic ring body, and the magnetic section is evenly arranged in the magnetic ring body by the polarity of putting upside down each other; The center offers a through hole on the upper surface of described magnetic ring body, is distributed with four small sircle holes of circumference five equilibrium around the through hole.
Described magnetic section is 18 pairs.
Described magnetic ring body is columnar structured.
The beneficial effect of the utility model is: the utility model is the one-time formed magnet ring of magnetic material, has guaranteed the concentricity of magnet ring and the uniformity of quality, is inlaid with at least two pairs of magnetic sections simultaneously in moulding simultaneously, makes the magnet ring of processing have multipole magnetic field.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the sectional structure sketch map of the utility model.
Fig. 2 is the plan structure sketch map of the utility model.
Among the figure: 1. magnetic ring body, 2. magnetic section, 3. through hole, 4. circular hole.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of magnetic plastics magnet ring shown in Fig. 1～2; Comprise magnetic ring body 1 and at least two circular arc magnetic sections 2; Magnetic ring body 1 is the injection molded integrative-structure of magnetic material, and magnetic section 2 is embedded in the magnetic ring body 1, and magnetic section 2 is evenly arranged in the magnetic ring body 1 by the polarity of putting upside down each other; The center offers a through hole 3 on the upper surface of magnetic ring body 1, is distributed with four small sircle holes 4 of circumference five equilibrium around the through hole 3.
Magnetic section 2 is 18 pairs.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
