Description
Technical field
The present invention relates to a kind of used for vehicle power set, the powerful driving motor for electric automobile of particularly a kind of actuating force.
Technical background
Fuel-engined vehicle all is global big problem to the exhausted problem of ecological construction, environmental pollution and the petroleum-based energy of the earth.The huge sum of money so countries in the world spare no expense, competitively development was not only free from environmental pollution but also open up the electric automobile that new forms of energy or utilization are charged as the energy, and particularly wherein driving power is big, power consumption is little and the automobile drive electric motor of superior performance.
At present, the employed driving motor for electric automobile in countries in the world is nothing more than direct current machine and AC permanent magnet synchronous motor.Though direct current machine can solve big speed adjustable range, large starting moment, complex structure, failure rate is higher.The AC magnetoelectric machine good speed adjustment features, efficient is higher, but moment is difficult for adjusting, and the vibration loss of excitation problem of permanent-magnet steel is difficult to be broken through, and the high-power design production of difficult realization.Reluctance motor is at power, and indexs such as moment and speed governing are all better, but volume is big, and noise is big.And several motors such as threephase asynchronous machine, its common weak point is that volume is big, Heavy Weight, performance lubricated and cooling are all very undesirable, thereby causes motor power consumption big, has directly influenced the vehicle performance and the use of electric automobile.So, form such as no matter AC magnetoelectric machine, or reluctance motor, efficient is all undesirable.
Summary of the invention
The purpose of the invention be to disclose a kind of drive powerful, volume is small and exquisite, weight is light, lubricated and the performance of cooling is all desirable, motor power consumption is little, and the driving motor for electric automobile of superior performance and physical property directly is provided for electric automobile.
In order to reach the technical scheme that the foregoing invention purpose taked be:
The present invention is the driving motor for electric automobile that is connected to form by rotor, stator, shell and base, it is characterized in that: described rotor 1, in order to obtain higher inductance value, compare with same type of motor, and adopt not only dark but also narrow groove.Be same purpose, rotor core also adopts the mouse-cage type structure, and punching is designed to deep trouth shape, and the ratio of high h of its groove and groove width b reaches about 1: 15, and common electric machine is only within 1: 4.The fan of cancellation conventional motors changes and establishes velocity transducer 5 on the rotor end ring.Such technological improvement scheme: one, both can make rotor 1 obtain very high driving induction amount, and can make rotor 1 dynamic balancing accuracy more much higher again than conventional motors; Two, the dynamic balancing difference of also having avoided existing rotor not only to cause because of fan when changed speed operation is reduced to minimumly, and noise also is well controlled, thereby makes motor reach the requirement of high dynamic balancing rate and noiselessness motor; Three, velocity transducer 5, and the speed that can exactly motor speed information be conveyed to shows and processing mechanism, is convenient to the monitoring motor rotating speed, to reach the control to running speed.
Described stator 2 adopts not only wide but also shallow groove.When the close design of stator magnet, general design of electrical motor power is less than 1.7T, and this design of electrical motor is 2T.Stator core high-quality low-loss silicon steel sheet stamped, the punching two sides scribbles 0.01 H level silicon steel sheet enamelled coating 2.3, is embedded with three symmetrical windings 2.4, and H class F insulation layer is all adopted in lead and insulation.Common electric machine all adopts the hot rolling sheet, and the two sides is not coated with insulating varnish, and whole motor is heated seriously.This technical scheme that we adopted can reduce same capability motor heat and reach 25%.Motor lead-out wire 2.2 is drawn from rear end cap 3.5, makes the motor profile as far as possible little, and lead-out wire does not have traditional terminal box, and directly draws with conductor wire.So both can guarantee the mechanical strength of support, and can reach again and reduce the effect that occupies the automobile useful space.
Described cooling water cavity 3 adopts the whole motor case water cavity 3 that is cooled to cool off around water flowing, water cavity adopts spirality channel 3.1 circulations, the heat that motor the is produced water that can be cooled efficiently, is equably taken away, spirality channel 3.1 substitutes the air-cooled radiating ribs of conventional motors shell, have spiral heat dissipation rib 3.2 but use the intermediate layer instead, cooperate the circulating water cavity double-decker that forms spirality channel 3.1 with external seal shell 3.3.Outer water flowing cooling of the heat that motor produces, its cooling rate is high.Spiral heat dissipation muscle 3.2 and external seal shell 3.3 materials adopt aluminium alloy casting, thereby alleviate complete machine weight.Motor of the same type all adopts support outer wall belt radiating ribs air-cooled structure, and radiating efficiency is very low, is unfavorable for improving the heat load design of motor.After adopting water-cooled structure, increased area of dissipation, improved radiating efficiency, the motor internal temperature can be delivered to rapidly on the spiral heat dissipation rib 3.2, and the water that is cooled has fast been taken away.
Base electric machine stand 4, end cap 3.4 all adopts high strength, and the casting of high duty alloy aluminium forms, and its mechanical strength has also been taked many special shapes greater than 200N/mm in structural design, thereby reaches in light weight, the instructions for use that mechanical strength is good.Electric machine stand of the same type all adopts cast iron or steel welding construction, though support intensity is higher, weight is very heavy, and the utmost point is not suitable for electric automobile and uses.The present invention adopts the support of alloy aluminum structure only to account for 34% of equal volume steel construction support weight, alleviates most possibly on the structural design and finishes construction weight.
The invention has the advantages that:
Usually variable-frequency motor can not surpass rated power operation, and rotating ratio is below 1: 3.And motor maximum power of the present invention can reach 3 times of rated power operations, and the rotating speed specific energy is more than 1: 5.In order to improve starting torque, when designing, adopts rotor punching deep trouth shape (figure two), and the high h of groove reaches 1: 15 with groove width b ratio, and common electric machine is all in 1: 4.When the close design of stator magnet, general design of electrical motor is less than 1.7T, and this design of electrical motor is 2T.By circuit, the magnetic structure design, this motor kilowatt weight is 1.8kg/kW, and common electric machine reaches 6kg/kW, therefore has only this motor to satisfy the technical requirement of electric automobile to drive motors fully.
