Background technology
The many advanced countries in the whole world; because global energy crisis; all looking for the outlet of own efficient energy-saving; the time meet the rare earth permanent-magnetic material that last century, the eighties occurred; people have been given a kind of thinking newly developed; the appearance of Rare-Earth Magnetic; except that temperature, all exceed several times or tens times more than ferrite permanent-magnet; people begin to research and develop motor with it; generator; especially various motor specials; the motor that comes out with its manufacturing demonstrates fully energy-efficient, thus the last century Mo and the beginning of this century each state all in the exploitation of grabbing the rare earth permanent magnet technology greatly, just developed kind more than 5000 with regard to the military various rare-earth electric motor of the U.S..The beyond challenge performance of rare earth permanent magnet machine is embodied in higher synthesis energy saving effect, satisfies the dynamic need of big starting torque of industry and breakdown torque multiple, low speed directly demand, the demand of multipole High Power Factor, the demand of high power density and the demand of kinetic control system of driving.The development of the foreigner on magneto for many years maintains the leading position always, and China just appoints academician's hosting far away to design and manufacture a 1090KW permanent magnetic motor in last century end by Tang, becomes the first in the world, because of can not industrialization putting the museum into.At global energy crisis exploitation energy-saving efficient motor is the task of top priority, and our this rare earth big country, carries out energetically and the application and the research that promote the permanent magnet synchronous motor system has great strategic importance.In the exploitation of magneto, always and then others runs, or brings drawing and make to others, or does " Sino-foreign joint venture ".Not own intellectual property, rare earth big country has become stranger's processing factory, the warehouse that rare earth big country has become the stranger not spend.But the problem of " low load with strong power " of one of two big propositions of world's motor still has report people's developmental research is not arranged, that is to say that the 5.5KW water pump will buy the 7.5KW motor, 7.5KW water pump will be bought the 11KW motor, the 22KW water pump will be bought the 30KW motor, and the low load with strong power phenomenon is very general, waste is very big.The main cause that causes " low load with strong power " is exactly that the magnetic effect of motor is bad a little less than both sides, the magnetic field height of motor, the middle magnetic field, and the closed too early or closure that lags behind of the magnetic line of force can not rationally be utilized magnetic energy.
The utility model content
The utility model technical issues that need to address are, overcome the deficiencies in the prior art, a kind of technical scheme of energy-saving efficient motor is provided, adopt the energy conversion rate height of the motor of technical solutions of the utility model, can improve magnetic effect and can rationally utilize magnetic energy again, reach purpose of energy saving.
Technical solution adopted in the utility model is: a kind of energy-saving efficient motor, it has casing, stator, rotor, the base that is connected as a single entity with casing, also are furnished with suspension ring on the casing, radiating ribs and the waterproof outgoing line device that is electrically connected with coil, rotor comprises rotor mandrel and sleeve rotor body, the sleeve rotor body is fixed in the rotor mandrel, it is characterized in that, described rotor mandrel has concentric axis hole, the axis hole wall has spiral grooves, be parallel to rotor mandrel in the rotor block and be evenly distributed with hole slot, the rotor block periphery is inlaid with the permanent magnetic material of geometry, described permanent magnetic material outer surface is not less than the outer surface of rotor, be adjacent on the outer surface of permanent magnetic material and be fixed with the conductive magnetic yoke of making by permeability magnetic material, conductive magnetic yoke can cover permanent magnetic material, the material of described conductive magnetic yoke is a silicon steel sheet, the industry soft iron, in the nodular cast iron any, the width of the air gap between described rotor and the stator are 4-8mm.
Described conductive magnetic yoke is furnished with some pyramidal projections with respect to the mid portion of the outer surface of rotor mandrel, and pyramidal projections is poly-magnetic ditch.
Described rotor block surface is provided with the permanent magnetic material of geometry, and part is embedded in the rotor block, part is exposed at rotor block in appearance.
Evenly have the filler hole on the described rotor block, the filler hole be built-in with can be centrifugal filler.
Be evenly distributed with fin on the casing inside cylindrical face, fin be shaped as " worker " font.
Ring sector between described two fins is embedded with coil, is close to ring sector (-shaped) coil inboard and is provided with circular arc silicon steel compressing tablet, and the silicon steel compressing tablet is stuck between the two fin heads.
Described casing inboard is provided with the cylindrical shape liner plectane that permeability magnetic material is made, and the liner plectane is close to the inboard fin of casing, and liner plectane inboard is provided with solenoid coil, and coil is close to the liner plectane.
The beneficial effects of the utility model are, adopt the technical solution of the utility model, the rotor periphery is inlaid with permanent magnetic material, the permanent magnetic material top, and being close to forever, material is fixed with the conductive magnetic yoke of being made by permeability magnetic material, conductive magnetic yoke can effectively make the magnetic line of force of permanent magnetic material form complete magnetic circuit, compare with the rotor that does not have conductive magnetic yoke, magnetic line of force loss has reduced by 30%, and can reduce the magnetization of permanent magnetic material to rotor mandrel and motor bearings, reduce the resistance in the motion, improve power output; The mid portion of conductive magnetic yoke is provided with some pyramidal projections, the action principle of pyramidal projections is discharged as cusp, play the effect of poly-magnetic, edge magnetic field intensity, the weak situation in magnetic field, middle part of permanent magnetic material have effectively been improved, make the Distribution of Magnetic Field trend of permanent magnetic material even, strengthened the magnetic effect of motor.Simultaneously, be parallel to rotor mandrel in the rotor block and be evenly distributed with hole slot, hole slot can be blocked permanent magnetic material in full rotor interior section flux loop, reduces the magnetic force loss, has increased inductive effects, has improved energy conversion rate, has realized energy-conservation.Rotor mandrel is hollow, and offers spiral grooves in axis hole hole wall inboard, and when motor rotated, spiral grooves had the wind-guiding effect, the heat of motor center can be helped diffusing; Simultaneously owing to adopt hollow rotor shafts, the motor shaft overstriking has reduced than the jerk value of original motor shaft, and better with big bearing fiting effect, because be hollow shaft, material has reduced, and its diameter of axle can strengthen, but can't multipurpose material, helps heat radiation.The stator core of the fin replacement silicon steel sheet that the good or setting-in of casting and " utmost point " are complementary in casing, help the heat radiation and the magnetic line of force and distribute, can increase the space of rule, help many rules and improve power grade, can save 50% silicon steel sheet and complicated processing cost, improve rate of finished products; Adding a magnetic conduction liner plectane in the iron-core less motor shell can increase magnetic conduction and Magnetic Shielding Effectiveness, thereby reduces iron loss and copper loss, raises the efficiency.Adopt the motor of utility model technical scheme to compare: to reduce iron loss with y series motor, the international new motor of IE, improved efficient, its power can improve 1.5-2 power grade, and efficient can improve 15-25%, power factor is all more than 90%, and can also save material when making.
