Construction Machine, Hybrid Hydraulic Excavator, And Output Torque Control Method For Motor Generator
A construction machine includes a swing speed detection unit that detects an actual swing speed of an upper structure, a lever command speed calculation unit that calculates a lever command speed based on an operation amount of a swing lever for swinging the upper structure, a torque command value calculation unit that calculates a torque command value based on a command speed based on the calculated lever command speed, a command value output unit that outputs a command torque to a rotary motor generator based on the torque command value calculated by the torque command value calculation unit and the swing speed detected by the swing speed detection unit, and a command value output restriction unit that restricts the output of the torque command value from the command value output unit under predetermined conditions.
