摘要： An excavator has a controller capable of setting target torque of a rotation motor in accordance with a speed deviation between target speed set in accordance with an operation amount of an operating lever and actual rotation speed and is provided with an inverter for detecting necessary torque for rotating an upper rotating body, the necessary torque being changed in accordance with a working state of the upper rotating body. The controller calculates a correction amount which is increased as increasing the torque and subtracts the correction amount from the target speed so as to set new target speed. A controller sets first target torque for driving the motor and second target torque for maintaining the upper rotating body on the spot on the basis of the actual speed, and operates the motor in accordance with the torque which has a larger absolute value in the same direction as the first target torque among both the torque.

摘要： In a hybrid excavator, a generator motor and a hydraulic pump are driven by using an engine as a power source. A battery is charged with power generated by the generator motor. A rotation motor is driven by the generator motor and the battery. The voltage of a DC bus is detected by a voltage sensor, and whether the battery is unusable is determined by a breakdown detector. When the battery becomes unusable, emergency evacuation control is performed so that the power consumption of the rotation motor will be suppressed to be less than or equal to the power generation of the generator motor while maintaining the DC bus voltage greater than or equal to the normal operation voltage of the system.

摘要： Of a plurality of hydraulic signals output from an operating device, a hydraulic signal is input into a control valve serving as a hydraulic control device without conversion, and particular hydraulic signals are converted into electric signals corresponding to their hydraulic pressures by signal converting devices, such as pressure sensors, and are then input into a controller. The controller controls the drive of an electric actuator, such as a rotating electric motor, on the basis of the electric signals. Hydraulic fluid flow paths communicating to the pressure sensors are connected to each other via a throttle, and air in one of the hydraulic fluid flow paths is removed using the other hydraulic fluid flow path.
