Research on Hybrid Excavator Energy Recovery Based on Electric Motor Driven Method
Abstract: Hybrid technology has become the key technology to improve energy efficiency of hydraulic exca-vators. Based on it, several energy recovery schemes have been widely studied. After analyzing the characteristics of ordinary excavator slewing mechanism, a kind of motor-driven rotary energy recovery solutions has been introduced. It uses an electric motor instead of hydraulic motor to drive the slewing mechanism, and uses super-capacitor to be energy storage unit. Meanwhile, the vector control algorithm has been used to control the electric motor. Simulation results show that this solution could achieve good energy recovery efficiency.
