Description
Technical field
The present invention relates to the automobile permanent magnet motor that a kind of use orientation silicon steel makes.
Background technology
At present, the world increasingly payes attention to environment, and fuel-engined vehicle is subject to get more and more as greenhouse gas emission main body
Restriction, fuel oil anxiety, rise of the oil price, reduce discharge capacity etc., it is contemplated that fuel-engined vehicle in future will be withdrawn from the market and be become not
Come.As fuel-engined vehicle substitute electric automobile so that its structure is simple, safety and comfort, economic and environment-friendly entrance people's sight line.This
Bright a kind of high rotation speed-high torque driving motor for electric automobile is exactly proposed in this context.Conventional electric automobile drive electric motor is to carry
The method that high output power of motor is adopted is：Increase armature length, expand electrical axis high（Motor radius）.Tradition side
Method increases armature length not only makes motor total quality increase volume change high power density than reducing, and reduces electric automobile one
Secondary property course continuation mileage, increases Productive statistics.And relatively-stationary electric automobile increase motor volume can enter for volume size
One step is made troubles.
Currently, market cold rolled silicon steel is divided into orientation silicon steel and non-orientation silicon steel by steel internal grain structure.So-called orientation
Silicon steel refers to that the arrangement of silicon steel sheet internal grain has clear and definite directionality, i.e. anisotropic；Non-orientation silicon steel refers in silicon steel sheet
Portion's crystal grain arrangement does not have clear and definite directionality, i.e. isotropic.General grain-oriented Si steel sheet is used for large, medium and small transformer, high frequency becomes
Depressor, pulse transformer, magnetic amplify choking-winding magnetic screen and magnetic switch；Non-orientation silicon steel deceive for large, medium and small motor,
Rectifier etc..For conventional grain-oriented Si steel sheet, it is divided into common and high magnetic strength two class, common orientation silicon steel rolls to average saturation magnetic
Flux density is 1.85T, and horizontal average saturation flux density is 1.35T, and from lateral to the scope rolled to 90 degree, different angles
Magnetic flux density on direction also increases with angle and increases；Rolling to average saturation magnetic strength of high magnetic induction grain-oriented silicon steel is 1.90T, horizontal
To average saturation flux density be 1.30T, and from lateral to the scope rolled to 90 degree, the magnetic flux density on different angle directions
Also increase with angle and increase；Common non-oriented silicon steel sheet direction magnetic flux density is identical, and average saturation flux density is
1.70T.And the magnetic flux density of silicon steel sheet is the important parameter of impact motor performance.Make now motor stator frequently with No yield point
Silicon steel, but non-orientation silicon steel, due to internal grain direction isotropism, thus leading to peak magnetic induction intensity not high, constrains
The raising of motor performance.Orientation silicon steel has clear and definite directionality therefore peak magnetic induction intensity relatively due to internal grain arrangement
Height, but answering direction due to the magnet steel of grain-oriented Si steel sheet is that single direction requires sensing stator center of circle direction not to be inconsistent with motor, so
Govern application in motor stator for the orientation silicon steel.If directly using orientation silicon steel to process motor stator with conventional method,
In the direction of magnetization of orientation silicon steel, no doubt magnetic induction intensity increases, but magnetic induction is dropped on the contrary significantly on unmagnetized direction
Low, so it is irrational for directly being processed with orientation silicon steel.Therefore urgently invent a kind of high using the high rotating speed of orientation silicon steel production
The motor stator of torque driving motor for electric automobile is to realize the production of high rotation speed-high torque driving motor for electric automobile.
Content of the invention
Improve power of motor for overcoming existing driving motor for electric automobile to pass through increase motor size and export drawback, this
A kind of high rotating speed high torque automobile drive electric motor of bright proposition.A kind of present invention design high torque (HT) high rotating speed electric automobile drives electricity
Machine, including Forced water cooling pipe joint, motor case, stator, motor bearings, machine shaft, motor three-phase lead-out wire, motor rotation
Become with temperature binding post, rotor it is characterised in that：Described motor stator is made up of grain-oriented Si steel sheet lamination, motor
Stator is overlapping and annulus that bend welding is constituted by the grain-oriented Si steel sheet of strip, and the direction of magnetization of grain-oriented Si steel sheet is towards fixed
The center of circle of sub- annulus.Stator tooth, stator yoke, stator winding groove are provided with stator, in stator winding groove, stator are installed
Winding.Grain-oriented Si steel sheet is carried out cross rolling, will be overlapping for the multi-disc grain-oriented Si steel sheet after rolling, all of grain-oriented Si steel sheet
The direction of magnetization is consistent, and the multi-disc grain-oriented Si steel sheet after overlap is curved towards the direction of magnetization of grain-oriented Si steel sheet, until being formed
Annulus, and in joint welding, then carry out stator tooth, stator yoke, the machining of stator winding groove.Advantages of the present invention
It is to carry out axial rolling using grain-oriented Si steel sheet and obtain motor stator to processing, improve motor power-mass ratio not
Improve output power of motor and peak torque, greatly improving motor performance is to drive electricity in the case of increasing motor volume
Machine is extensively applied further and is established important foundation.
