Embodiment
Technical scheme is described in further detail below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to
It is as described below.
A kind of list stator and double-rotor coaxial motor, refers to shown in attached drawing 1 and attached drawing 2, including stator module, internal rotor group
Part and outer rotor component；The stator module includes winding stator 10 and stator coil 13, before one end of winding stator 10 is placed on
On end cap 12, the other end of winding stator 10 passes through rear end cap 11, and is equipped with first gear 19 in the termination of winding stator 10；Institute
Stator coil 13 is stated to be wrapped among the winding stator 10；The both ends of the internal rotor component are respectively sleeved in the winding stator
Outside 10, the outer rotor component is sleeved on the internal rotor component outer ring, the both ends of outer rotor component respectively with rear end cap 11 with
And drive end bearing bracket 12 is connected, the outer surface of the outer rotor component is additionally provided with some second gears 18, and the internal rotor component includes
Internal rotor 15 and internal rotor permanent-magnetic body 14, internal rotor permanent-magnetic body 14 are distributed on the inner wall of internal rotor 15, internal rotor 15 with
Winding stator 10 is coaxially disposed, and which causes internal rotor permanent-magnetic body 14 outside stator coil 13, can be so that 15 He of internal rotor
Outer rotor 17 can operate at the same time.
Further, 15 outer surface of internal rotor is also wound with internal rotor coil, and outer rotor component includes outer rotor and outer turn
Sub- permanent magnet 16, outer rotor permanent magnet 16 are distributed on the inner wall of outer rotor 17, and outer rotor 17 and winding stator 10 are coaxial
Set.First gear 19 is meshed with motor power gear.It is overall fixing axle to wind stator 10.
It should be noted that internal rotor 15 and outer rotor 17 can operate at the same time, also, connect different power supplys and can divide
Shi Jinhang is operated, and internal rotor 15 works or outer rotor 17 works and is independent of each other.So two rotors can will be allowed to provide not
Same output torque is rationally utilized.The part for selecting output torque big when needing high torque is worked, it is necessary to low torsion
Low torque part is selected to work during square.
When as Power unit of electric vehicle, different motor modes can be selected to work.Can in low torque and
High torque is switched over using to reach different work requirements, and the moment of torsion of motor is equal to the mechanical output divided by rotor of motor
Mechanical angular speed, the bundle number of mechanical angular speed and coil is directly proportional.So coil bundle number more at most moment of torsion is smaller, it is fewer to prick number
Moment of torsion is bigger.Such as internal rotor 15 is few as number is pricked, it is more that outer rotor 17, which pricks number, then 15 motor of internal rotor is high torque, outside
Rotor 17 is low torque.It is the work of selection inner rotor motor, it is necessary to which when high rotating speed selects that electric car needs high torque in motion
External rotor electric machine work (motor speed and coil bundle number are directly proportional).Common electric machine can only be determined by the control of electric current and voltage
Determine the torque output of motor.What is driven when using low voltage and electric current is the motor of larger load, can cause more machines
Tool loss in efficiency.And double-rotor machine can select the inner rotor motor of more Smaller load to operate, the loss of mechanical efficiency is reduced.Together
When electronic control unit control birotor can also be used to work at the same time to maximize the output power that motor performance provides bigger.Can
To say double-rotor machine no matter on energy saving, in performance or space availability ratio all advantageously.
Embodiment described above only expresses the embodiment of the present invention, its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.
