Description
Technical field
The present invention relates to a kind of electric car travel increasing device flywheel-type TRT, belong to car electrics technical field.
Background technology
Although pure electric automobile has the advantages that energy-saving and environmental protection, zero-emission, continual mileage is limited.If electric energy is not
Exhaust before arriving at, automobile cannot advance.Distance increasing unit is made up of with electromotor electromotor, can give accumulator at any time
Electric energy supplement, solves the problems, such as that pure electric automobile continual mileage is short.Therefore develop a kind of pure electric automobile distance increasing unit high power
Density, the electromotor of high performance-price ratio are highly desirable to.
Existing report at present, the Chevrolet Volt car of General Motors Corporation, the Riich M1 car of Chery Automobiles company,
Audi's A1 e-tron car is provided with distance increasing unit.If the generator main that the distance increasing unit of report uses both at home and abroad at present adopts
Magneto or electric excitation generator, magneto has the advantages that high efficiency, high power density, has broader answering
Use prospect.
In existing technology, the TRT of flywheel-type structure can be used for reference following patent of invention and expect.Authorize sends out
Bright patent：Centrifugal permanent-magnet starter generator, grant number：ZL 200510044107.7, has invented one kind and has been fastened around flying
Wheel outer rotor inwall has the starter-generator of polylith permanent magnet material.Act the armature winding employed with the armature winding generating electricity each
Independent, the number of coil is equal with permanent magnet number, and permanent magnet N pole and S pole are spaced, the interlaced winding of two kinds of windings
Different depth in stator core.Because coil number is equal with permanent magnet number, therefore the motor of this structure can only be single-phase
Motor.
In authorized patent of invention：Three-phase semiwave controlled rectification type voltage regulation electronic controller, for a kind of 12 poles 36
A kind of three-phase semiwave controlled rectification type voltage regulation electronic controller of knowing clearly left by the magneto of groove.This traditional magneto
One extremely corresponds to three grooves, and therefore each coil is wound on three teeth, has three coils outside each tooth, radially between coil
On have more overlap, therefore copper factor is difficult to improve.And the motor of this integer groove winding also to there is cogging torque big
The shortcomings of.
The patent of invention authorizing：A kind of motor for automobile idle-free system, the patent No.：201310174948.4 it is proposed that
A kind of stator poles are 12k, and rotor number of poles is 2p, and the electric motor of automobile of 10k≤2p≤14k, wherein k, p are natural number.At present
On electric bicycle and other low-speed electronic car, most widely used motor is 46 pole 51 groove motor.Above two motor is all
Fractional-slot concentratred winding, number of poles is many, and the leakage field between two poles is more serious.The motor of fractional-slot concentratred winding also exists simultaneously
Winding distribution factor little the problems such as.
Excessive exploitation with China's rare earth resources and the increase year by year of rare-earth permanent magnet demand, rare earth permanent-magnetic material
Price is also more and more expensive, or even accounted for an electric vehicle motor 40%.Therefore, the usage amount reducing rare earth permanent-magnetic material can
Significantly to reduce the production cost of enterprise.
Technology disclosed by the invention is all different from such scheme.The electromagnet topological structure of the optimization taken herein first
The usage amount of permanent magnet can be significantly reduced.On the basis of this is built upon emulation and the calculated results.Inventor is through right
The modeling of magneto and Theoretical Calculation, show that the thickness increasing permanent magnet under to a certain degree can not improve the defeated of motor
Go out power.By this conclusion, the present invention proposes a permanent magnet and magnetic conductive soft iron constitutes jointly the knot of a pair of magnetic pole
Structure scheme, simultaneously the mechanism of the present invention also effectively reduce the magnetic flux leakage of interpolar.
In addition, the technology of the present invention neither adopts the integer groove motor technology of each extremely corresponding groove or three grooves,
It is not the fractional-slot winding that number of poles and slot number are more or less the same, but a kind of new teeth groove being interposed between the two, and be directed to
This new teeth groove proposes winding allocation plan.Winding configuration due to the particularity of structure, under this new teeth groove coupling
Do not have one kind can be with blanket rule.The winding allocation plan of therefore this paper claim is a special scheme, not
It is a kind of universal rule.But this new teeth groove matching scheme possesses, and integer groove winding distribution factor is big, fractional-slot winding
The little overall merit of cogging torque.
