Abstract
The utility model discloses a neodymium-iron-boron high permanent magnet micromotor which belongs to a micromotor used for vehicles, comprising high magnetic energy magnet storage steel which is made of 25-30 mega high neodymium-iron-boron materials, a built-up rotor which is once thermally solidified by applanation injection phthalic acid which is embedded by non-cored windings, etc. The utility model has the advantages of large power, large braking moment, less power consumption, less noise, light weight, corrosion resistance, high temperature resistance, anti-ageing and distortion, etc. Therefore, the utility model is suitable for higher temperature environment, the performance of the micromotor is raised, and the working range is enlarged, so the utility model is a product with practicability and popularization value.
Description
The utility model belongs to a kind of automobile-use electrical micro-machine.
At present the permanent magnet of the miniature cocurrent electromotor of making in the world mainly is to adopt ferrite or aluminium, cobalt, nickel to make.Armature coil is to adopt lap winding type to use the plastic mould pressing moulding then, and its motor braking moment is little, and power output is little, power consumption is big, noise is big, can not be suitable for growing new automobile and the machinery needs to micromachine.
The utility model purpose is to make a kind of high permanent magnet micromotor made from NdFeB material, the advantage that it has, and power is big, braking moment is big, little power consumption, noise are little, in light weight, save material.
This electrical micro-machine is made up of shell (1), magnet steel (4), armature (7), axis (2), ball bearing (6), and its casing (1) employing does not have cutting and stretches, and can save raw material, be convenient to tissue production in enormous quantities at a high speed.Magnet steel (4) is to adopt 25～30,000,000 high ferromagnetism NdFeB materials difficult to understand to make, and it is simple to adopt type, is convenient to mould manufacturing and oriented moulding production in enormous quantities.Cut into several pieces preferably 22～28 millimeters of six lengths of a film by line, wide 10～15 millimeters, thick 2～5 millimeters rectangle removes chamfering or fan-shaped permanent-magnet block, then with diffusing on the uniform magnetic conduction casing that is bonded in built-up rotor (7) one sides of shape, form loop with the casing of opposite side, form the axial magnetic field air gap.This magnetic pole has high energy product, is six times that the present world uses the ferrite magnetic energy product, and this cloth method can satisfy motor can save magnetic material again to the requirement in magnetic field, reduces cost, and alleviates motor weight.Armature (7) is to take not have the iron core form, and with coil coiled waveform winding, it is flat that setting-in becomes, and puts into mould then, adds the stupid dipotassium acid of phosphorus, is heated to 130 ℃ to 150 ℃, and one-step solidification becomes disc, removes traditional handicrafts such as silicon steel sheet and jet-bedding from.Under the situation of 65 ℃ of ambient temperatures, prove that by 1000 hours continuous runnings this armature has high temperature resistant, and is corrosion-resistant, be difficult for advantages such as aging distortion.Motor still can operate as normal when temperature surpassed 100 ℃, and the special environment that adapts at higher temperature uses.With present Japanese like product SSW-998(m) motor contrast test (seeing the following form) shows: braking moment is bigger by 82% than Japan, and power output is big by 37%, power consumptive province 31%, noise reduces by 3.5 decibels.Thereby improved every performance of micromachine, enlarged range of application.In Domestic Automotive Industry and other mechanical industry, adopt the high permanent magnet micro motor of this neodymium iron boron, will improve its competitiveness.
