AI Technical Summary

Technical Problem

Traditional speed reducers waste a lot of kinetic energy during braking. Existing speed reducers with generators have low power generation efficiency and are prone to generating reverse drag torque, which affects system stability and control accuracy.

Method used

The system employs a combination of a permanent magnet synchronous motor, an overrunning clutch, and a flexible coupling. The speed is increased from low to high-efficiency power generation speed through a speed-increasing transmission mechanism. The overrunning clutch automatically disengages power transmission when necessary, and intelligent control is achieved by combining a speed sensor and a controller.

Benefits of technology

It achieves efficient energy recovery, improves energy utilization, avoids energy waste, ensures stable system operation, and reduces the risk of failure.
