As shown in drawings, 1 magnet, 2 internal layer ladders, 3 outer layer ladders.
Detailed description of the invention
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
A kind of ferrite bead for motor of the present utility model, including 8 pieces of magnets 1,8 pieces of magnet 1 two ends are circumferentially staggered with N pole, S pole, and magnet 1 is provided with ladder i.e. internal layer ladder 2 and the outer layer ladder 3 of two ring-type protrusions from inside to outside, and outer layer ladder 3 is located at outside internal layer ladder 2.Ferrite magnetic 1 is the pole anisotropy magnet taking radial multi-pole to be orientated, and magnet ring the most circumferentially imposes the magnetic field that N, S extremely interlock magnet is carried out multipole orientation, set 8 pieces of magnets altogether.Internal layer ladder 2, outer layer ladder 3 and magnet 1 are one-body molded.
In the present embodiment, the ladder 2,3 of ferrite bead two ring-type protrusions from inside to outside, the height of internal layer ladder 2 is 50mm, thickness is 3mm, the height of outer layer ladder 3 is 30mm, thickness is 3mm, the upper surface of internal layer ladder 2 is 25mm with the distance of the upper surface of magnet 1, the lower surface of internal layer ladder 2 is 25mm with the distance of the lower surface of magnet 1, the upper surface of outer layer ladder 3 is 10mm with the distance of the upper surface of internal layer ladder 2, and the lower surface of outer layer ladder 3 is 10mm with the distance of the lower surface of internal layer ladder 2.
In the present embodiment, the internal diameter of ferrite bead is 40mm, and the thickness of the most non-protruding part of thickness of magnet 1 is 5mm, and height is 100mm.
Ferrite bead simple in construction of the present utility model, being designed to 8 pieces of magnets makes magnet ring possess the most intensive magnetic line of force, thus obtain stronger magnetic force, the design of multi-step shape makes the magnetic field in the middle part of magnet ring be obviously enhanced, magnet ring volume can also be reduced, reduce the consumption of Ferrite Material, thus reduce motor volume, reduce production cost；Use Ferrite Material to make magnet ring possess the strongest remanence strength and coercivity, greatly strengthen the magnetic of magnet ring, additionally, ferritic production cost is lower than similar rare earth permanent magnet, industry, civilian production can be widely used in.
Above-mentioned detailed description of the invention is used for illustrating this utility model; rather than this utility model is limited; in spirit of the present utility model and scope of the claims, any modifications and changes that this utility model is made, both fall within protection domain of the present utility model.
