Embodiment Construction
[0031] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0032] Such as figure 1 As shown, the embodiment of the present invention provides a motor return current control system, including a motion platform 1, the bottom of the motion platform 1 is provided with a plurality of driving wheels 9 and universal wheels 7, and the driving wheels 9 pass through a The elastic suspension device is elastically connected with the motion platform 1 . Through the elastic suspension device, on the one hand, the effect of shock absorption and buffering can be realized to ensure the stability of the motion platform on bumpy roads, and on the other hand, the main invention points of the present invention can be realized.
[0033] The moving platform 1 is fixedly provided with a driving motor (not shown in the figure), and the driving motor can be located inside the moving platform 1, or can be directly fixed on the mov...

The invention relates to a motor back current control system. The system comprises a motion platform, a plurality of driving wheels and universal wheels are arranged at the bottom of the motion platform, and the driving wheels are elastically connected with the motion platform through an elastic hanging device; a driving motor is also fixedly arranged on the motion platform, the driving wheels areprovided with a central rotating shaft, and the driving motor drives the driving wheels to rotate around the central rotating shaft; the elastic hanging device is also provided with a lower left fixing sheet and a lower right fixing sheet on both sides of the central rotating shaft respectively, an upper left fixing sheet corresponding to the lower left fixing sheet is fixedly arranged on the motion platform in the direction corresponding to the vertical direction of the lower left fixing sheet, and an upper right fixing sheet corresponding to the lower right fixing sheet is fixedly arrangedon the motion platform in the direction corresponding to the vertical direction of the lower right fixing sheet; electromagnets are arranged on the upper left fixing sheet, the lower left fixing sheet, the upper right fixing sheet and the lower right fixing sheet respectively. According to the scheme, the generation of reverse current of a motor is effectively controlled, and it is ensured that amotor drive module is not burned during hand pushing.
Description
technical field [0001] The invention relates to the control field of a linear moving mechanism with a motor, in particular to a motor return current control system, a control method and a robot with the system. Background technique [0002] At present, among various drive structures, motor direct drive or motor indirect drive is widely used, and the technology of motor drive is relatively mature. When the motor is applied to the drive control of linear movement mechanism, the One problem is that when the motor is powered off or the drive motor has no power, when the platform is directly pushed by hand (the motor drive mechanism in the platform directly or indirectly drives the drive wheel to rotate), since the output shaft of the motor and the drive wheel train are If the drive is connected, the rotation of the driving wheel train will drive the motor shaft to rotate, and the motor will output a current, which will easily cause reverse current in the motor and cause fatal da...
