Abstract
The utility model provides a magnet assembly used for motor. The magnet assembly comprises a plurality of magnets. Magnets are in insulation connection by utilization of a bonding agent. A plurality of insulation supporters are arranged in the bonding agent. The insulation supporters are spherical insulation supporters with the same size. The volume ratio of the insulation supporters in the bonding agent is 30%-60%. The insulation supporters with a certain proportion are added in the bonding agent and used for insulation connection of each small magnet, and a magnet bonding assembly is formed. When the magnet bonding assembly is fixed a clamp, the bonding agent cannot be extruded in abundance, and the insulating performance among the magnets is guaranteed.
Description
Technical field
The utility model relates to a kind of magnet assembly for motor.
background technology
Medium-to-high grade Nd-Fe-Bo permanent magnet material has a wide range of applications on motor with its high magnetic property and higher cost performance.But in the use procedure of motor, the generation of eddy current is inevitable, due to the temperature characterisitic of Nd-Fe-Bo permanent magnet material, eddy-current heating can reduce the magnetic property of neodymium iron boron magnetic body greatly, thereby reduce the transformation efficiency of motor, often need to select the higher more expensive magnet of performance, increase production cost.In order to reduce the generation of eddy current, reduce production costs, originally the whole piece magnet design needing is become to magnet bonded assembly, assembly is by bonding the forming of magnet insulation of fritter one fritter, under the constant prerequisite of original magnetic force, due to mutually insulated between each fritter magnet, can reduce significantly eddy current, but magnet assembly is in the time using fixture fixing, the bonding agent that prior art adopts is easily extruded in a large number, and between fritter magnet, insulating properties is poor, and abutting edge variable thickness causes, and thickness is non-adjustable, can not meet client's requirement.
Utility model content
The utility model provides the motor that a kind of insulation property are better, thickness of adhibited layer is adjustable magnet assembly.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
For a magnet assembly for motor, comprise multiple magnets, between each magnet, adopt insulating adhesive agent to connect, in described bonding agent, be provided with multiple insulation stents.
Preferably, the spherical insulating supporting material that described insulation stent is same size.
Preferably, the volume accounting of described insulation stent in bonding agent is 30%～60%.
From above technical scheme, the utlity model has following beneficial effect:
In bonding agent, be provided with a certain proportion of insulation stent be used for insulation connect each small magnet, form a magnet bonded assembly, when with fixture fixed magnets bonded assembly, can not cause bonding agent to be extruded in a large number, guarantee the insulation property between each magnet, and can control thickness of adhibited layer by the size that changes insulation stent, meet the cooperation requirement of client to magnet assembly size and magnetic flux.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, magnet, 2, bonding agent, 3, insulation stent.
Embodiment
Below in conjunction with accompanying drawing, a kind of preferred implementation of the present utility model is described in detail.
This magnet assembly is made up of multiple magnets 1, in order to reduce the generation of eddy current, between each magnet 1, must insulation connect, as shown in Figure 1, three magnets 1 are connected together by bonding agent 2 insulating stickies successively, in this bonding agent 2, be provided with multiple insulation stents 3, the space proportion of insulation stent 3 shared adhesive linkages is 30%～60%, can be by the thickness of the adjusted size adhesive linkage of change insulation stent 3, the spherical support substance that insulation stent 3 is same size, be preferably the controlled bead of processing dimension, in the time making bonding agent, the bead of same size is mixed and dropped into.
Carrying out magnet assembly when bonding, first the bonding agent that contains insulation stent 32 is evenly bonded on the end face of magnet, the magnet of bonding respective numbers successively as required again, then compress with special fixture, insulation stent 3 is located under pressure automatically, support the end face of adjacent two magnets, according to the character of bonding agent used 2, carry out normal temperature cure or heating cure, in bonding agent 2, contain a certain proportion of insulation stent 3, so the situation that can not cause bonding agent 2 to be extruded in a large number because of pressure when with fixture fixed magnets assembly occurs, guarantee the mutually insulated between each magnet 1.
The above execution mode is only that preferred implementation of the present utility model is described; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection range of claims of the present utility model.
Claims (3)
1. for a magnet assembly for motor, comprise multiple magnets, between each magnet, adopt insulating adhesive agent to connect, it is characterized in that: in described bonding agent, be provided with multiple insulation stents.
2. a kind of magnet assembly for motor according to claim 1, is characterized in that: the spherical insulating supporting material that described insulation stent is same size.
