The motor is characterized in that: winding slots are axially and uniformly distributed on the inner surface of the stator, magnetic steel block slots are axially and uniformly distributed on the outer surface of the rotor, and rare earth magnetic steel blocks are embedded into the magnetic steel block slots. The motor has the advantages of overcoming the defects of a fan and a water pump of dragging equipment of 'dragging a cart by a big horse', meeting the requirements according to the new technical scheme that the electrified motor can be quickly self-started, the voltage is not changed and the current is changed after starting, and realizing high efficiency and energy conservation.
Description
Technical field
The present invention relates to a kind of motor in the mechanical industry field, especially relate to a kind of self-starting high-performance energy-saving rare earth motor.
Background technology
Motor popular kind that adds various motor specials in the world's we can say several ten thousand kinds; Big and small motor is because performance demands; Nearly all be put into poor efficiency highly energy-consuming motor, seldom partly develop into the high-performance energy-saving rare earth motor, the major part that the economic expert predicts the year two thousand fifty world's motor will be replaced by rare-earth electric motor.
The world today is because energy crisis, the needs of biological environment, and each state is all going all out with energy-saving and emission-reduction; Energy-saving and emission-reduction mainly to as if this poor and underdeveloped developing power of tackling key problem, especially China of electric system, difficulty more; The motor that China is on active service now equally is the y serial motors with various countries, the world; The y serial motors is at the about 75%-80% of the occupation rate of countries in the world, have up to 85%, and the general purpose y series of China accounts for total motor platform several 70%; But the y serial motors is eliminated, just because its poor efficiency highly energy-consuming; Advanced flourishing western countries just stopped to produce and sell in last century, and had announced the motor new standard in 2005 on the world convention, i.e. IE1, IE2, IE3, China has adopted this standard simultaneously, and in 2009 formal enforcement; And in electric system; The motor of China is introduced because at that time due to the national conditions, y be motor in the body design than just low 10 percentage points of prototypes; In system; Operational efficiency is than the low 20-30% of prototype efficient, and this is the poor efficiency highly energy-consuming incurable disease that original technology is brought, be exactly the tragedy that brings of this incurable disease be that the water pump of buying a 3KW will be joined a 5.5KW motor; Buy a 7.5KW water pump and will join a 11KW motor, behind pump working, the former just uses 2.5KW; The latter just with 6.0-6.5KW, waste extremely seriously, see table one,
Table one
Countries in the world are in electric system, and the total amount of motor traction blower fan and water pump accounts for about 45% of motor total amount, and this is in world's motor two big fatal problems " low load with strong power "; Someone carries unmanned the solution; In the standard of IE1, IE2, IE3 and rare-earth permanent-magnet electric machine that motor big club in the world's announces, do not occur " overcoming low load with strong power " type yet and occur, 11KW motor band 7.5KW water pump in the new IEC serial motors in the world still not solve; This phenomenon has not only been wasted electric energy but also has been wasted a large amount of raw material; And change distance owing to high starting with the 11kW rare-earth electric motor, and brought loss to coupling mechanism again, making a general survey of does not all have suitable type both at home and abroad.Overcome " low load with strong power ".
Summary of the invention
The objective of the invention is according to energy-saving and emission-reduction needs, according to the needs in market, according to the needs of electromechanics trade development, research and develop a kind of self-starting high-performance energy-saving rare earth specific type of electric machine that overcomes " low load with strong power ".
Technical scheme: comprise stator and the base of rotor and bottom of shell in the casing, casing, said stator inner surface is axially evenly laid winding slot, and said rotor outer surface is axially evenly laid the magnetic steel ingot groove, inlays the Rare-Earth Magnetic bloom in the magnetic steel ingot groove.
Technique scheme also can be improved to: between the groove that said stator and rotor surface are evenly laid differential seat angle is arranged, motor is self-starting fast after energising.
Technique scheme is preferred: said differential seat angle is the 10-12 degree.
Technique scheme also can be improved to: for being used for the high-speed cruising motor, the Rare-Earth Magnetic bloom outer peripheral of inlaying in the said magnetic steel ingot groove is established the sheet metal or the silk of a circle magnetic conduction.
Technique scheme also can be improved to: closed in order to reduce cost with magnetic circuit, in said rotor inboard the soft iron tube is set.
Technique scheme also can be improved to: 4,6,8 axially extending bores are set on the said soft iron tube, enlarge area of dissipation, increase radiating rate.
Beneficial effect: overcome the driven equipment blower fan of " overcoming low load with strong power " and the shortcoming of water pump; Realize motor self-starting fast after energising, starting back voltage is constant and electric current changes, and a kind of new solution of design; Satisfy the new architecture of this demand, and realize energy-efficient.
Description of drawings
Accompanying drawing is the internal structure cutaway view of present embodiment, and 3 is squirrel-cage bars among the figure.
Embodiment
With reference to accompanying drawing; Present embodiment mainly comprises stator 2 and the base 11 of rotor 6 and casing 1 bottom in the casing 1, casing 1, and said stator 2 inner surface axials are evenly laid winding slot 4, and said rotor 6 outer surfaces are axially evenly laid magnetic steel ingot groove 5; Inlay Rare-Earth Magnetic bloom 10 in the magnetic steel ingot groove 5; Between the groove that evenly lay on said stator 2 and rotor 6 surfaces differential seat angle is arranged, said differential seat angle is 11 degree, and is closed with magnetic circuit in order to reduce cost; In said rotor 6 inboards soft iron tube 9 is set, 4 axially extending bores 7 are set on the said soft iron tube 9.
For the motor of high-speed cruising, Rare-Earth Magnetic bloom 10 outsides that can in said magnetic steel ingot groove 5, inlay enclose the sheet metal or the silk of a circle magnetic conduction.
Embodiment: the present invention is an example with the type 9.0kW between Y7.5kW four utmost points and Y11kW four utmost points, and limit is set at the explanation of 9.0kW four utmost points as follows: on the basis of said structure, and the lengthening stator core; Winding with certain angle is embedded within the groove 4, like this because the lengthening of stator core 2, so also lengthening thereupon of the length of winding; Do to be pressed into casing 1 after the insulation processing; The rotor 6 that silicon steel sheet is formed is passed by squirrel-cage bar 3 that three-piece is formed with soft iron tube 9 and axle 8 in the back and stator pack is dressed up new motor, owing to the lengthening of stator and rotor; Under the voltage of 380V, induced current increases, so power reaches 9kW.
Behind the stator silicon steel sheet cover material, wanted remove contamination, to reduce stray loss as far as possible; Laminate by new design length; To use state's graticule selecting for use of electromagnetic wire; By forming winding in the new length embedded groove 4, the stator that will have winding this moment is put into oven dry behind the dipping lacquer in the dipping lacquer case, clear chamber, is pressed into casing;
