Abstract
The utility model relates to an exchange permanent -magnet direct -drive torque motors rotor subassembly, its characterized in that: it includes from outside to inside each other cover barring ring gear (1) and rotor (2) of establishing the inner circle surface of rotor (2) is provided with the arc piece magnet steel (3) the same with rotor (2) radian, laminate with the inner circle closed -up surface of rotor (2) magnet steel (3), the magnet steel divide into N, S the two poles of the earth, a week is 20, 10 piece N, 10 piece S, divide 2 to paste in the inner circle surface of rotor (2), amount to 40, separate through nylon parting bead (4) between two adjacent magnet steel (3) in one, magnet steel (3) seamless laminating between two together, louvre (5) that with magnet steel (3) are linked together are seted up at the both sides face of rotor (2). This rotor subassembly can effectively strengthen permanent -magnet machine's starting performance, and starting current is little, and simple structure, and heat -sinking capability is strong, reduces the eddy current loss of motor to improve the electric efficiency.
Description
Technical field
The utility model relates to magneto technical field, particularly relates to a kind of motor rotor component adopting the straight drive square of AC permanent-magnet.
Background technology
The straight drive torque motor of AC permanent-magnet is along with power electronic device technology, and Novel variable-frequency technology, the development of Computer Control Technology produces.It belongs to novel rising industry, high-end sci-tech product.
Asynchronous machine starting current is large, and be 5-6 times of permanent magnet direct-drive torque motor starting current, the motor device matched like this, mains supply equipment is corresponding increasing also, thus adds the supporting cost of corollary equipment.The rotor structure of asynchronous starting magneto has two kinds of forms usually, i.e. cage modle p-m rotor and solid p-m rotor.Cage modle p-m rotor adopts laminar, and the rotor of Solid Rotor Asynchronous Motors is made by monoblock ferromagnetic material, relies on the torque of the eddy current generation responded to by rotor core and start in start-up course; The starting current of cage-shaped motor is large and detent torque is less, easily occur that disconnected cage even burns the situation of machine in the occasion that some starting performance are higher, mainly because the leakage field of magnetic core air gap wrap online in eddy current loss cause line bag overheated and also make magnetic core overheated by conduction and cause whole electromagnetic circuit to lose efficacy causing.
Utility model content
Technical problem to be solved in the utility model provides a kind of AC permanent-magnet straight drive torque motor rotor assembly for above-mentioned prior art, reduces the eddy current loss of motor, improve useful life while reaching raising electric efficiency.
The technical scheme in the invention for solving the above technical problem is: a kind of AC permanent-magnet straight drive torque motor rotor assembly, it comprises jiggering gear ring mutually sheathed from outside to inside and rotor, the inner peripheral surface of described rotor is provided with the arc-like sheet magnet steel identical with rotor radian, the inner peripheral surface of magnet steel and rotor fits tightly, magnet steel is divided into N, S the two poles of the earth, order is N, S, N within one week, be 20 pieces, 10 pieces of N, 10 pieces of S, 2 row are divided to be pasted on the inner peripheral surface of rotor, amount to 40 pieces, separated by nylon parting bead between adjacent two magnet steel in a column, magnet steel between two row is together seamless applying, the louvre be connected with magnet steel is offered in the two sides of rotor.
Compared with prior art, the utility model has the advantage of:
This rotor assembly effectively can strengthen the starting performance of magneto, and starting current is little, and structure is simple, and heat-sinking capability is strong, reduces the eddy current loss of motor, thus improves electric efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation in the utility model embodiment;
Fig. 2 is the AA cutaway view of Fig. 1.
Wherein:
Jiggering gear ring 1, rotor 2, magnet steel 3, nylon parting bead 4, louvre 5.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Fig. 1-Fig. 2, a kind of AC permanent-magnet straight drive torque motor rotor assembly in the present embodiment, comprise jiggering gear ring 1 mutually sheathed from outside to inside and rotor 2, the inner peripheral surface of described rotor 2 is provided with the arc-like sheet magnet steel 3(identical with rotor 2 radian and permanent magnet), magnet steel 3 fits tightly with the inner peripheral surface of rotor 2, magnet steel is divided into N, S the two poles of the earth, order is N, S, N within one week, be 20 pieces, 10 pieces of N, 10 pieces of S, 2 row are divided to be pasted on the inner peripheral surface of rotor 2, amount to 40 pieces, separated by high-strength nylon parting bead 4 between adjacent two magnet steel 3 in a column, magnet steel 3 between two row is together seamless applying, separate with nylon parting bead between arc-like sheet magnet steel and reduce magnet steel air gap, thus reduce the eddy current loss caused because of the leakage field of magnet steel air gap and cause motor overheating, offer the louvre 5 be connected with magnet steel 3 in the two sides of rotor 2 simultaneously, this louvre 5 is upright openings, the heat that magnet steel 3 produces is derived by rotor 2 after louvre 5, thus the heat of motor internal can be reduced.
In addition to the implementation, the utility model also includes other execution modes, the technical scheme that all employing equivalents or equivalent substitute mode are formed, within the protection range that all should fall into the utility model claim.
