Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Whole description, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiments of the invention, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, belongs to the scope of protection of the invention.
As shown in figure 3, Fig. 3 is the stator winding arrangement schematic diagram of Double-stator motor provided by the invention.
A kind of Double-stator motor is present embodiments provided, its radial arrangement of motor interior edge has the first motor stator 1, motor to turn
Son and the second motor stator 2；Also include being connected with the three-phase windings of the first motor stator 1 and controlling the first motor control of its work
Device 3 processed, and be connected with the three-phase windings of the second motor stator 2 and control the second electric machine controller 3 of its work.Motor is using double
Stator structure, meet the job requirement of the first motor stator 1 and the second motor stator 2 simultaneously by rotor, reduce motor and turn
The usage amount of sub- permanent magnet, reduces motor cost.First motor stator 1 and the second motor stator 2 are absolute construction, by first
Electric machine controller 3 connects the three-phase windings of the first motor stator 1, and the three of the second motor stator 2 are connected by the second electric machine controller 4
Phase winding, pass through the independent control of the work to the first motor stator 1 and the second motor stator 2 so that motor has the first electricity
The motor stator 2 of machine stator 1 and second works independently or multiple high efficient districts of work in combination, so as to be in different road conditions in vehicle
When, different power is exported, meets the requirement of vehicle difference high efficient district.
In the specific embodiment of this case one, the first motor stator 1 is the electric motor internal stator for being arranged at rotor inner ring；The
Two motor stators 2 are the outer stator of motor for being arranged at rotor outer ring.First motor stator 1 and the second motor stator 2 use
Along motor radial arrangement structure, the axial length of motor is reduced, is easy to its arrangement on vehicle.First motor stator 1 and
Two motor stators 2 are respectively arranged at inner ring and the outer ring of rotor, so as to make full use of the radial space of motor, in the first electricity
When machine stator 1 works, rotor is as its outer rotor.When the second motor stator 2 works, rotor is as the second motor
The internal rotor of stator 2.Rotor is arranged between the first motor stator 1 and the second motor stator 2, makes it while meets the
The need of work of one rotor and the second rotor.
In the specific embodiment of this case one, the first motor stator 1 includes the first silicon steel sheet, the first stator winding and it is entered
First cooling water cavity of row cooling.
In the specific embodiment of this case one, the second motor stator 2 includes the second silicon steel sheet, the second stator winding and it is entered
Second cooling water cavity of row cooling.
First motor stator 1 and the second motor stator 2 can use conventional motor to form structure, respectively by silicon steel sheet and stator
Winding forms.First cooling water cavity is set in the first motor stator, the second cooling water cavity is set in the second motor stator, due to double
Stator structure shares one group of electronics rotor, produces more heat transfer during work, passes through the first cooling water cavity individually arranged and second
Cooling water cavity, work independently at work, the inner ring to rotor and outer ring are synchronously radiated respectively, optimize the heat pipe of motor
Reason system, improve the overload capacity of motor.
In the specific embodiment of this case one, motor includes the low torsion operating mode of high speed that the first motor stator 1 works independently, second
The high high speed for turning round operating mode and the first motor stator 1 and the second motor stator 2 synchronous working of low speed that motor stator 2 works independently
Height turns round operating mode.Because the first motor stator 1 and the second motor stator 2 are located at inner ring and the outer ring of rotor respectively, when first
When electronics stator 1 works independently, the low torsion demand of vehicle high-speed can be met, now vehicle is in speed no-load and high, and the high rotating speed of motor is low
Torque output power is little, and the high efficient district of settable motor is partial to the low torsion operating mode of high speed of high rpm low torque.
When the second motor stator 2 works independently, vehicle operation need to meet that vehicle low speed is high and turn round need in fully loaded low-speed situations
Ask, motor is in the little state of slow-speed of revolution high torque power, and the high torsion operating mode of low speed of fully loaded low speed is partial in the high school district of motor.
When the first motor stator 1 and the second motor stator 2 work asynchronously, setting vehicle operation in fully loaded high-speed case,
Interior external stator works simultaneously, by the superposition of the two high efficient district, may be such that high efficient district meets that the high speed of vehicle is high and turns round operating mode.
Based on the Double-stator motor provided in above-described embodiment, present invention also offers a kind of electric automobile, setting in it
Power motor, the power motor that the electric automobile is provided with are the Double-stator motor provided in above-described embodiment.
