摘　　要：大型液压机使用伺服电机会引起克服重力下失速所需设置的抗衡力和重力势能的浪费,针对这种情况提出一种补偿伺服电机拖动力矩的能量回收装置,结合相应的回路和蓄能器,大大减少了电机能耗。对于设计的结构和工作特性,初步估计了在一定应用环境和工作参数下的节能效果,对大型液压机选用合适的功率启动和能量回收方案提供了一定的参考价值。Aiming at the counterbalance force required to overcome the stall under gravity and the waste of gravitational potential energy of large hydraulic press using servo motor,an energy recovery device is proposed to compensate the driving torque of servo motor.This device,combined with corresponding circuits and accumulators,significantly reduces motor energy consumption.The energy-saving effect of this device and its structural design and operational characteristics are initially estimated under specific application environments and operating parameters.This provides valuable reference for selecting appropriate power startup and energy recovery schemes in large hydraulic presses.
