Self-check and Warning for Machine Internal Impedance
The machine torque estimation and control system developed by the SuGong team displays the machine’s dynamic load torque, dynamic rotational speed, and dynamic motor current on the control system’s touchscreen.
When the machine leaves the factory, the system automatically learns and memorizes the no-load driving torque at the time of出厂. During subsequent machine inspections or maintenance, users can test the machine’s no-load driving torque and compare it with the no-load driving torque recorded at the time of出厂 to determine whether the internal resistance of the machine is normal.
When the machine’s no-load driving torque exceeds the factory-set no-load driving torque, the system will automatically trigger an alarm, prompting the user to inspect or maintain the equipment (e.g., damaged transmission chain, lubrication failure, severe contamination, structural deformation...).
The system automatically determines the current load condition—light-load state, over-anticipated load state, heavy-load state, or jamming trend—based on the magnitude of the torque the machine is bearing and the trend of load resistance.
Based on the machine’s current load status and combined with the user’s selections, the system can provide corresponding autonomous responses: In a light-load condition, the system will initiate autonomous alarms, automatically adjust the speed, and delay shutdown; in the event of an overload or pre-emptive overload condition, the system will trigger an autonomous alarm, automatically reduce the speed, and delay shutdown; when a jamming trend is detected, the system will proactively shut down within 100 milliseconds; and when crossing obstacles, the system will actively reduce speed to safely navigate the obstacle and then autonomously resume normal speed after clearing the obstacle.
The system automatically generates and stores graphs of the machine’s dynamic load torque and dynamic speed curves.
| Basic Features | Function Description | |||||||||||||||||||||||||||||||||||||||||||||
| Dynamic Torque Display | The system dynamically displays the machine’s dynamic load torque on the touchscreen in the form of bar graphs, trend charts, and numerical values, enabling users to intuitively understand the machine’s current load status. | |||||||||||||||||||||||||||||||||||||||||||||
| Dynamic Speed Display | The system dynamically displays the machine’s current speed on the touchscreen in the form of bar charts, trend graphs, and numerical values, enabling users to intuitively grasp the machine’s current speed. | |||||||||||||||||||||||||||||||||||||||||||||
| Self-check of internal resistance torque upon machine出厂 | When the machine leaves the factory, the system automatically learns and memorizes the no-load driving torque at the time of manufacture, which serves as a reference or comparison during subsequent inspections or maintenance. | |||||||||||||||||||||||||||||||||||||||||||||
| Internal Resistance Torque Self-Check | When the machine is being inspected or maintained, users can test its no-load drive torque and compare it with the no-load drive torque specified at the time of manufacture to determine whether the internal resistance of the machine is normal. | |||||||||||||||||||||||||||||||||||||||||||||
| Internal Resistance Torque Warning | Once the machine’s no-load drive torque exceeds the factory-set no-load drive torque, the system will automatically trigger an alarm, prompting the user to inspect or maintain the equipment (e.g., damaged transmission chain, lubrication failure, severe contamination, structural deformation...). | |||||||||||||||||||||||||||||||||||||||||||||
| Light-load judgment | Once the machine’s load torque falls below the user-set light-load threshold, the system will automatically determine that the operating condition is a light-load state. | |||||||||||||||||||||||||||||||||||||||||||||
| Light-load autonomous response | When the machine is operating under light load, the system can autonomously respond according to the user’s selection: issuing alarm notifications, automatically switching to low-speed or high-speed operation, or delaying shutdown. | |||||||||||||||||||||||||||||||||||||||||||||
| Judgment of Super-Predictive Load Blocking | Once the machine’s load torque exceeds the predefined threshold for known load resistance set by the user, the system will automatically determine that the load resistance has surpassed the pre-defined threshold. | |||||||||||||||||||||||||||||||||||||||||||||
| Autonomous Response to Over-Prediction and Load Blocking | When the machine is in an over-predicted load-blocking state, the system can respond autonomously based on the user’s selection: issuing an alarm notification, automatically switching to low-speed operation, or delaying shutdown. | |||||||||||||||||||||||||||||||||||||||||||||
| Overload Detection | Once the machine’s load torque exceeds the machine’s rated overload torque threshold, the system will automatically determine that an overload condition has been reached. | |||||||||||||||||||||||||||||||||||||||||||||
| Overloaded Autonomous Response | When the machine is overloaded, the system can respond autonomously according to the user’s choice: issuing an alarm, automatically switching to low-speed operation, performing an immediate shutdown, or initiating a countdown shutdown (the approach time for shutdown is correlated with the degree of overload). | |||||||||||||||||||||||||||||||||||||||||||||
| Judgment of the jamming trend | When the machine’s load torque exceeds the jamming torque threshold and the machine’s rotational speed shows a tendency to stall, the system will autonomously determine that a jamming trend is occurring. | |||||||||||||||||||||||||||||||||||||||||||||
| Autonomous Response to Jamming | When the machine is trending toward a jam, the system will automatically shut down within 100 milliseconds. | |||||||||||||||||||||||||||||||||||||||||||||
| Self-responsive to overcoming obstacles | When the machine’s load torque reaches a threshold for overcoming an obstacle, if the user has enabled the autonomous obstacle-response function, the machine will autonomously detect the obstacle and proactively reduce its speed to safely navigate it. After successfully clearing the obstacle, the machine will automatically resume its original speed. | |||||||||||||||||||||||||||||||||||||||||||||
| Superfluid protection for motors | The system displays the three-phase dynamic currents of the motor on the touchscreen. After the motor experiences overcurrent, the system can, according to the user’s selection, either automatically trigger an alarm or initiate a countdown shutdown (the approach time for shutdown is correlated with the degree of overcurrent). | |||||||||||||||||||||||||||||||||||||||||||||
| Phase-loss protection for motors | Once the motor enters a phase-loss condition, the system will automatically shut down within 50 milliseconds. | |||||||||||||||||||||||||||||||||||||||||||||
| Dynamic Load Curve Graph | The system automatically generates and stores dynamic load curves for motors or machines, which users can review and copy to analyze historical operating conditions and conduct research. | |||||||||||||||||||||||||||||||||||||||||||||
| Dynamic Speed Profile | The system automatically generates and stores dynamic speed curves for motors or machines, which users can review and copy to analyze historical operating conditions and conduct research. | |||||||||||||||||||||||||||||||||||||||||||||
