Abstract
The invention discloses a permanent magnet synchronous counter-rotating dual-rotor motor driving device, which comprises wheels, a driving motor and a transmission assembly. The driving motor has two power output ends. The two power output ends are connected with the wheels through universal joint transmission pieces. An outer rotor with an armature winding and a permanent magnet inner rotor are installed on the rotating shaft of the driving motor. A speed reducing planetary row is installed on one side of the rotating shaft. A reversing speed reducing planetary row is installed on the corresponding other side of the rotating shaft. The armature winding on the outer rotor is connected with a motor controller. The motor controller is electrically connected with a power supply. The power of the outer rotor of the permanent magnet synchronous counter-rotating dual-rotor motor driving device is transmitted to the wheel through the speed reducing planetary row and a constant-speed universal joint transmission mechanism on one side. The power of the inner rotor is transmitted to the wheel on the side sequentially through a reversing speed reducing mechanism and a constant-speed universal joint transmission mechanism on the other side. Not only can the wheels on the two sides be driven to run in the same direction, but also a differential function is obtained.

Background technology
Traditional motor generally is by a stator, and a rotor constitutes.Because motor has only a rotor, can only realize the single shaft output of single speed.In application scenarios such as torpedo propelling, electric automobile, wind power generations, needing motor to have provides the twin shaft fan-out capability of two independent rotation speed, and conventional motors can't realize this function.
Summary of the invention
To the problems referred to above, the object of the present invention is to provide a kind of permanent-magnet synchronous to changeing the double-rotor machine drive unit, it is used in the electric motor car, can drive the both sides wheel and go in the same way, and have differential function, to solve the problem that motor exists in the prior art.
The objective of the invention is to realize through following technical scheme:
A kind of permanent-magnet synchronous is to changeing the double-rotor machine drive unit, and it comprises wheel, drive motors and driving member, wherein; Two clutch ends of said drive motors tool, these two clutch ends connect wheel through driving member, and the said drive motors forward and backward end cap that comprises casing and be installed on the casing two ends; Be provided with rotating shaft in the said casing; The external rotor and the permanent magnet internal rotor of charged pivot winding are installed in the said rotating shaft, and on the side of said rotating shaft reducing gear are installed, communtation deceleration mechanism is installed corresponding to the opposite side of rotating shaft; Charged pivot winding on the said external rotor is connected with electric machine controller, and said electric machine controller and power supply electrically connect.
Especially, said driving member is the constant velocity cardan joint driving member.
Especially, said reducing gear is reduction planetary row, and corresponding communtation deceleration mechanism is communtation deceleration planet row.
Especially, the charged pivot winding on the said external rotor is through being connected with electric machine controller through slip ring and lead.
Beneficial effect of the present invention does; Said permanent-magnet synchronous is to producing equal and opposite in direction, electromagnetic torque in the opposite direction between the external rotor of the charged pivot winding that changes the double-rotor machine drive unit and the permanent magnet internal rotor; Under the electromagnetic torque effect, inner and outer rotors produces absolute rotation in the opposite direction.The reduction planetary row of power warp one side of external rotor, constant velocity cardan joint transmission mechanism are to the wheel transmission; The power of internal rotor transmits to this sidecar wheel through the communtation deceleration mechanism and the constant velocity cardan joint transmission mechanism of opposite side successively, also can be that the inner and outer rotors exchange connects.Double-rotor machine can drive the both sides wheel and goes in the same way like this, and has differential function.
