Abstract
The utility model discloses a special high-speed permanent magnet synchronous driving motor for electric automobiles, which comprises a stator, a stator coil and a rotor, wherein the stator coil is arranged on the stator, permanent magnets are arranged inside the rotor, and the permanent magnets are arranged in a cylindrical structure. The special high-speed permanent magnet synchronous driving motor for electric automobiles replaces exciting windings with permanent magnet materials, and the traditional synchronous motors are changed into high-speed permanent magnet synchronous motors. The special high-speed permanent magnet synchronous driving motor for electric automobiles has the advantaged of being small in volume, low in loss, high in efficiency and rotating speed, long in service life, simple in structure and the like, and plays an important role in the fields of energy conservation and environmental protection.
Description
Technical field
The utility model relates to a kind of drive motors, is specifically related to the special-purpose high-speed permanent magnetic synchronous driving motor of a kind of electric automobile.
Background technology
The magneto of current use (PMM), PMM are can be divided into permanent magnet DC motor (PMDCM) and permanent magnet AC motor (also claiming permanent magnetic brushless PMBLM) according to the electric current of importing the motor terminals.Permanent magnet DC motor (PMDCM) replaces with magnet exciting coil and magnetic pole permanent magnet band; Make traditional Wound-rotor type direct current machine become the PMDCM motor; It is higher that the power density of PMDCM motor and efficient can become; Armature reaction reduces, and commutator is improved, and these advantages have improved its application on electric automobile.But because of its commutator can produce torque ripple, simultaneously brush friction and radio frequency interference, and they all need periodic maintenance, thereby the application of PMDCM motor no longer includes attraction.This Electric Machine Control is simple, can only be used on the dilly, in today that energy savings and environmental protection come into one's own day by day, seems very necessary for the raising of driving motor for electric automobile technology.
The utility model content
The purpose of the utility model is to provide a kind of high-speed permanent magnetic synchronous driving motor of electric automobile special use, adopts permanent magnetic material to replace excitation winding, and traditional synchronous machine has been become high-speed permanent magnetic synchronous motor.
In order to achieve the above object, the technical scheme of the utility model employing is:
The high-speed permanent magnetic synchronous driving motor that a kind of electric automobile is special-purpose comprises stator, stator coil and rotor, and said stator coil is arranged on the stator, wherein, is provided with permanent magnet in the rotor.
Further, said permanent magnet adopts cylindrical structural to arrange.
The beneficial effect of the utility model is:
The utility model adopts permanent magnetic material to replace excitation winding; Traditional synchronous machine has been become high-speed permanent magnetic synchronous motor; The stator of permagnetic synchronous motor is identical with traditional synchronous machine, and it has advanced advantages such as volume is little, loss is low, efficient is high, rotating speed is high, the life-span is long, simple in structure, in energy savings and field of environment protection effect particular importance; It not only can be used on the electric automobile, can also be used in the military and national defense space flight.
The position that the utility model is installed on rotor according to permanent magnet is different, and PMSM has adopted the cylindrical radial magnetic field structure, has improved its power and efficient to a great extent.And make that its volume becomes littler, inertia is lower, advantage such as response is faster and speed adjustable range is wideer, thereby make it become the substituent of following high speed electric electric motor of automobile.
Other advantages, target and the characteristic of the utility model will be set forth in specification subsequently to a certain extent; And to a certain extent; Based on being conspicuous to those skilled in the art, perhaps can from the practice of the utility model, obtain instruction to investigating of hereinafter.The target of the utility model can realize through the structure that is particularly pointed out in following specification or the accompanying drawing and obtain with other advantages.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe in detail:
Referring to Fig. 1, the utility model comprises stator 1, rotor 2, stator coil 3 and permanent magnet 4, and stator coil 3 is arranged on the stator 1, and permanent magnet 4 is located in the rotor 2.Adopt permanent magnetic material to replace existing excitation winding, traditional synchronous machine has been become permagnetic synchronous motor PMSM, the stator 1 of permagnetic synchronous motor PMSM is identical with traditional synchronous machine; Rotor 2 adopts radial permanent magnet magnet 4 as magnetic pole; Its rotor 2 is rotated with rotating magnetic field synchronously, and the rotating speed of rotating magnetic field depends on supply frequency, and sinusoidal wave stator current and sinusoidal back electromotive force interact and produce torque; Having produced is desirable especially permanent torque, so be referred to as steady torque.
Position according to permanent magnet is installed on rotor 2 is different; The utility model has adopted the cylindrical radial magnetic field structure; Its power and efficient have been improved to a great extent; And advantage such as make that its volume becomes littler, inertia is lower, response is faster and speed adjustable range is wideer makes it become the substituent of following high speed electric electric motor of automobile.
Stator 1 is made up of coil and cooling mechanism, because therefore the restriction that vehicle-mounted motor has living space and the requirement of higher fuel service efficiency can come reduced volume by greater efficiency or with preferable radiating mode under same power output.
Rotor 2 has adopted built-in permanent magnetic iron 4 according to the implantation mode of permanent magnetism, because built-in permanent magnetic iron 4 has and can bear higher vibration, magnet such as is difficult for flying off at advantage during high speed, therefore is particularly suitable for high-side driver engineering and the use of high speed electric automobile.
Above embodiment only is used to explain the preferred implementation of the utility model; But the utility model is not limited to above-mentioned execution mode; In the ken that said field those of ordinary skill is possessed; Any modification of being done within spirit of the utility model and the principle, be equal to and substitute and improvement etc., it all should be encompassed within the technical scheme scope that the utility model asks for protection.
