A kind of electric car is additionally provided with novel.
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clear, complete description, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
As shown in figure 3, Fig. 3 is the stator winding arragement construction schematic diagram of Double-stator motor provided by the utility model.
A kind of Double-stator motor is present embodiments provided, first motor stator 1 is radially disposed in motor, motor turns
Son and the second motor stator 2；It further include the first motor control that its work is connect and controlled with the three-phase windings of first motor stator 1
Device 3 processed, and the second electric machine controller 3 of its work is connect and controlled with the three-phase windings of the second motor stator 2.Motor is using double
Stator structure is met the job requirement of first motor stator 1 and the second motor stator 2 by rotor simultaneously, is reduced motor and is turned
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 first motor stator 1, connects the three of the second motor stator 2 by the second electric machine controller 4
Phase winding, by the independent control of the work to first motor stator 1 and the second motor stator 2, so that motor has the first electricity
Machine stator 1 and the second motor stator 2 work independently or multiple high efficient districts of work in combination, to be in different road conditions in vehicle
When, different power is exported, the requirement of vehicle difference high efficient district is met.
In one specific embodiment of this case, first motor stator 1 is the electric motor internal stator for being set to rotor inner ring；The
Two motor stators 2 are the outer stator of motor for being set to rotor outer ring.First motor stator 1 and the second motor stator 2 use
Along motor radial direction arragement construction, the axial length of motor is reduced, convenient for its arrangement on vehicle.First motor stator 1 and
Two motor stators 2 are respectively arranged at the inner ring and outer ring of rotor, so that the radial space of motor is made full use of, in the first electricity
When machine stator 1 works, rotor is as its outer rotor.When the work of the second motor stator 2, rotor is as the second motor
The internal rotor of stator 2.Rotor is set between first motor stator 1 and the second motor stator 2, it is made while meeting the
The need of work of one rotor and the second rotor.
