Description
Technical field
What the present invention relates to is a kind of permanent magnetism vector motor, belongs to design of electrical motor and manufacturing technology field.
Technical background
General magneto divides from rotor structure, is divided into following two classes:
The first kind is that built-in magnet steel adds cage grooves, by power frequency supply or frequency converter, can realize motor rotation, be referred to as the magneto of asynchronous starting, as shown in Figure 1, the stator of this class magneto and winding processing technology and traditional asynchronous machine are consistent for its rotor structure.The technique of rotor is first laminated to the desired height of electric parameter by the rotor silicon steel punching shown in Fig. 1, then by by aluminium extrusion process at the interior note aluminium of rotor mouse cage 11 and the aluminium forming in each cage grooves that the aluminium end ring of two ends of rotor makes produce parallel-connection structure; Then the magnet steel groove 12 at rotor is embedded in magnet steel 13 fixing, then carries out metalworking to guarantee to dispel the residual aluminum of rotor surface and the electric clearance between rotor.Finally rotor is installed together by traditional motor process.
Equations of The Second Kind is the rotor structure of surface-mount type magnet steel, by supporting corresponding servo controller or DC brushless controller, realize the running of motor, be referred to as permanent-magnet servo motor or non-brush permanent-magnet DC motor (because the rotor structure of non-brush permanent-magnet DC motor and permanent-magnet servo motor is similar, so this two classes motor is classified as to rotor of the same type by rotor structure at this).Its rotor structure as shown in Figure 2, the stator of this type of magneto and winding processing technology and the first kind are basic identical, so its rotor be first by rotor core Excircle machining to design load, when being 20# steel, core material completes Excircle machining unshakable in one's determination by metalworking, when core material is silicon steel sheet, by punch die, completes Excircle machining unshakable in one's determination and be laminated to the iron degree of growing tall of requirement.Then the magnet steel of arc is fixed on rotor core cylindrical with powerful glue, the motor that power of motor and torque are larger need to separately be fixed overcoat at magnet steel outer surface; Finally rotor is installed together by traditional motor process.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of, on the basis of existing magneto manufacturing process, improve, simplify motor processing technology, reduced spillage of material and electric power energy consumption, improve the permanent magnetism vector motor of motor efficiency.
The object of the invention is to complete by following technical solution, described a kind of permanent magnetism vector motor, it mainly contains housing, stator, stator winding and rotor form, described stator by blocks of rotor punching through being overrided to form up and down, two parts up and down of described rotor punching are mutually rotary shifted to form the oblique utmost point from centre, with laser welding technology, upper and lower two-part rotor punching is soldered and form rotor integral body by the laser weld groove that arranges in the outer rim of rotor punching; In the middle of described rotor punching, there are axis hole, the periphery of axis hole to offer uniform magnet steel groove, between magnet steel groove, are provided with magnet isolation tank between two; In axis hole in the middle of described rotor punching, be inserted in motor shaft; In magnet steel groove in described rotor punching, according to upper and lower two parts, by the N/S utmost point, embedded successively magnet steel respectively; And be respectively pressed into a vexed plate of stainless steel for guaranteeing that magnet steel can not be deviate from magnet steel groove at the axial plane of upper and lower two parts rotor punching.
Two parts up and down of rotor punching of the present invention are rotary shifted 4.5-5 degree from centre; On the cylindrical of described rotor punching, be provided with eccentric angle, and make integral rotor profile be quincunx.
The present invention changes magneto manufacturing process in the past, and simple flow reduces raw material loss, comprises and reduces technological process power consumption etc.; Permanent magnetism vector motor of the present invention, the novelty of its structure is mainly reflected on rotor, has cancelled the epitrochanterian cage-shaped structure of the first kind, does not need aluminium extrusion process; Simultaneously and the comparison of Equations of The Second Kind permanent magnet machine rotor, the magnet steel embedding structure adopting again, does not need rotor core cylindrical to carry out secondary operations, does not need magnet steel raw material, from square cut camber, to reduce the raw-material waste of magnet steel.Thereby do not need to carry out magnet steel Surface Mount technique simultaneously and avoid using the super glue that environment is had to pollution, for high-power large torque motor, need on the cylindrical of rotor magnetic steel, separately not be fixed again cover yet, from controlling, can cancel motor rear portion encoder (servo controller feedback is used) or magnet ring (brushless controller feedback is used) structure.
The present invention improves on the basis of existing magneto manufacturing process, and it is simple, reasonable that it has overall structure, simplifies motor processing technology, reduced spillage of material and electric power energy consumption, improved the features such as efficiency of motor.
