Problems solved by technology
Since the motor has only one rotor, it can only achieve single-speed single-axis output
In applications such as torpedo propulsion, electric vehicles, and wind power generation, the motor is required to have a dual-axis output capability that provides two independent speeds, which cannot be achieved by traditional motors

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.
Description
technical field [0001] The invention relates to a motor driving device, in particular to a permanent magnet synchronous counter-rotating double-rotor motor driving device. Background technique [0002] Traditional motors generally consist of a stator and a rotor. Since the motor has only one rotor, it can only achieve single-speed single-axis output. In applications such as torpedo propulsion, electric vehicles, and wind power generation, the motor is required to have dual-axis output capabilities that provide two independent speeds, which cannot be achieved by traditional motors. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a permanent magnet synchronous counter-rotating dual-rotor motor drive device, which is used on an electric vehicle, can drive the wheels on both sides to drive in the same direction, and has a differential function, so as to solve the problems in the prior art. Problems with the ...
