Description
Technical field
The utility model relates to a kind of multi-pole magnet-rings to be orientated device, and the neodymium iron boron of mainly a kind of square wave magnet ring is orientated device.
Background technique
In recent years, the demand of permanent-magnet ferrite multi-pole magnet-ring rapid technological improvement, client is also more and more diversified.Currently,
Flux density distribution in the most common multi-pole magnet-ring outer surface is mostly sine wave or approximate sine wave distribution on the market, can seldom see square wave
The magnet ring of formal distribution.For certain special motors, the magnet ring of square-wave profile is needed matching.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of neodymium iron boron of square wave magnet ring
It is orientated device, the structure by being orientated device to neodymium iron boron designs, and realizes the magnet ring of square distribution.
The purpose of this utility model is completed by following technical solution.The neodymium iron boron of this square wave magnet ring is orientated
Device includes mainly 45# iron skeleton, and magnetic patch group, the 45# iron skeleton is cylindrical, and is equipped on the inner wall of 45# iron skeleton
Several grooves, magnetic patch group are fixedly connected on the groove of 45# iron skeleton, and surround lopping.
Further, the magnetic patch group mainly includes first group of magnetic patch, second group of magnetic patch, third group magnetic patch and the 4th
Group magnetic patch, every group of magnetic patch group are set there are two thick ndfeb magnet and two thin ndfeb magnets, wherein every two thickness neodymium-iron-boron
Thin ndfeb magnet there are two being set among block.
Further, first group of magnetic patch is identical as third group magnetic patch polarity, second group of magnetic patch and the 4th group of magnetic
Block polarity is opposite.
The utility model has the following beneficial effects:
1, the shape of groove and magnetic patch group correspond, and are easily installed and fix；
2, realize that ferrite multistage magnet ring outer surface flux density distribution curve is square wave；
3, the magnetic patch different using thickness, and arranged in prescribed way, it is easy to accomplish the magnet ring of square.

Specific embodiment
Detailed introduction is done to the utility model below in conjunction with attached drawing:
Embodiment 1: the neodymium iron boron of this square wave magnet ring is orientated device, mainly includes 45# iron skeleton 1, and magnetic patch group is described
45# iron skeleton 1 is cylindrical, and several grooves are equipped on the inner wall of 45# iron skeleton 1, and magnetic patch group is fixedly connected on 45# gagger
On the groove of frame 1, and surround lopping.The shape and magnetic patch group of groove correspond, and are easily installed and fix；Realize that ferrite is more
Grade magnet ring outer surface flux density distribution curve is square wave.
Embodiment 2: on the basis of embodiment 1, as shown in Figure 1, the magnetic patch group mainly includes first group of magnetic patch 2,
Second group of magnetic patch 3, third group magnetic patch 4 and the 4th group of magnetic patch 5, every group of magnetic patch group set that there are two thick ndfeb magnets 6 and two thin
Ndfeb magnet 7 is wherein set among every two thickness ndfeb magnet 6 there are two thin ndfeb magnet 7.Using the different magnetic of thickness
Block, and arranged in prescribed way, it is easy to accomplish the magnet ring of square.
Embodiment 3: on the basis of embodiment 2, as shown in Fig. 2, first group of magnetic patch 2 and 4 pole of third group magnetic patch
Property is identical, and second group of magnetic patch 3 is opposite with the 4th group of 5 polarity of magnetic patch.Using adjacent magnetoresistive polarity on the contrary, realizing pole anisotropy forever
Magnetic ferrites multi-pole magnet-ring square wave.
It is understood that it will be understood by those skilled in the art that the technical solution of the utility model and utility model structure
Think of is subject to equivalent substitution or change all and should belong to the protection scope of the utility model the attached claims.
