The magnetic ring comprises a magnetic ring body and at least two pairs of arc-shaped magnetic sections, the magnetic body is molded integrally by magnetic materials in an injection manner, the magnetic sections are embedded in the magnetic ring body and uniformly arranged in the magnetic ring body in a polarity reversal manner, the upper surface of the magnetic ring body is connected with an inclined surface towards one side of the inner wall of the magnetic ring body, the tail end of the inclined surface is connected with an end face, four cylindrical bumps are uniformly distributed on the end face, the bottom surface of the magnetic ring body is provided with a step towards one side of the inner wall of the magnetic ring body, and the step is provided with two round holes identical in size and position. The uniformity in concentricity and quality of the magnetic ring molded by magnetic materials is guaranteed, and meanwhile, the molded magnetic ring has multi-pole field since the at least two pairs of magnetic sections are embedded during molding.
Description
Technical field
The utility model relates to the electrical micro-machine technical field, especially a kind of 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 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 magnet ring; Comprise magnetic ring body and at least two pairs of 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; The magnetic section is evenly arranged in the magnetic ring body by the polarity of putting upside down each other; The upper surface of described magnetic ring body is connected with an inclined-plane towards magnetic ring body inwall one side, and the inclined-plane is connecting an end face, is distributed with four cylindrical bumps of circumference five equilibrium on the end face; The bottom surface of magnetic ring body is provided with a step towards magnetic ring body inwall one side, offers two sizes, the identical circular hole in position on the step.
Described magnetic Duan Weisi is right.
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.
