Description
Technical field
The utility model is related to a kind of forced rotor of magnet, is related to such a magnet forced in more detail
Rotor, it causes simple for assembly processization of rotor and magnet such that it is able to save manufacturing expense, and in magnet
The magnetic steel plate that rotor is prevented from during press-in assembling is damaged or magnet generation breakage.
Background technology
Generally, motor is configured to, and will be transferred to rotary shaft as the revolving force of the rotor of rotor (rotor).Rotary shaft
When being connected to load, load is driven by rotary shaft.Rotor is by the electricity with the stator as stator (stator)
Magnetic interaction and rotate.
The axiality of rotor is extremely important for the operation of motor.Cause when rotor rotates to make an uproar because axiality is poor
Sound and vibrations increase, and the efficiency of motor may be reduced.Additionally, the vibrations of rotor are transferred directly to rotary shaft, so as to drive
There may be bigger noise and vibrations during load.
The rotor includes rotor core, magnet (example：Permanent magnet) and rotary shaft.
So that multiple magnetic steel plate stackings are so as to manufacture rotor core.Magnet is arranged at the core bore of rotor core (or rotor core)
(core hole).Rotary shaft is incorporated into rotor core in rotatable form.
Especially, magnetic steel plate is in order that the direction of principal axis flux leakage for obtaining rotor core is minimized and is laminated.Each magnetic
Steel plate is blocked to iron plate or steel plate and is molded (forming) by suppressing (pressing), so as to be made multiple, and is led to
Cross lamination process and form rotor core.
Especially, it is manufactured into for brushless direct-current (Brushless DC in order that obtaining rotor core:BLDC) motor, it is considered to magnetic pole
Number (number of poles) (example：Sextupole, the ends of the earth, ten poles) and multiple magnet are arranged at circular rotor core.
According to prior art in order to magnet to be arranged at the inside of rotor core, compared to core bore, the sectional area of magnet is smaller
Formed.
Thus, there is gap or interval between magnet and core bore, therefore although magnet is inserted into core bore, but now
The magnet for being inserted is difficult to remain secured to the state of core bore.
Thus, in the prior art, thermosetting sticker or forming agent are coated or flow between core bore and magnet, and
By the heating of heating furnace, magnet is firmly fixed at core bore by adhesion.
But, thus assembled using the existing magnet of sticker or forming agent or fixing means be by handwork reality
Existing, the interval that should be embodied as between equally spaced magnet simultaneously differs, and be coated on the thickness of the sticker in internal rotor face
Do not fix, deformed during technique so as to be sintered and then easily deformed in the adhesion position of magnet.
Additionally, by the use of sticker or forming agent existing magnet assemble method use as chemical material sticker or
Forming agent, so that there are the following problems：So that fee of material increases, and causes that technique increases, and the time of solidification is needed, and glued
The first injection sample (sample) and substandard products and expense increase discarded are produced when agent or forming agent injection.
Additionally, in existing another technology, using raised or utilize calking (calking) method, so as to attempting so that
Core bore and magnet interfix.
But, the problem of existing another technology is the gap increase between magnet and core bore.For example, just by core or filling out
Gap is directly contacted with for the projection of magnet, should be caused more than the gap at least up to 2mm (1mm=1t) of magnet and core bore, with
Just the raised press-in for making it possible magnet while itself bend.Now, the thickness of magnetic steel plate can be 0.3t.Change sentence
Talk about, existing another technology is because the gap of core bore and magnet is more than 2mm, therefore the disadvantage is that, is caused in rotor core
Magnetic saturation is too high, so as to magnet performance cannot be ensured.
Additionally, existing another technical pattern cannot be produced largely and volume production.In other words, manufacture has projection in addition
Core, so as in stacking, each identical interval necessarily be formed projection, therefore manufactures, or be difficult real the disadvantage is that, being difficult to realize
Existing bulge clearance matching, and so that having the magnetic steel plate of projection and without raised magnetic steel plate, i.e. so that two kinds of magnetic
Steel plate matching it is raised between the upper and lower every so that being assembled while consistent one by one, therefore automatic mass cannot be realized.
