    摘要： An electric motor that is fixed to a revolving frame, an electrical equipment that is supported by the revolving frame by using a vibration absorption mount, and a cable for establishing a connection between the electric motor and the electrical equipment are provided. A connector mounting member having an outer shape smaller than that of a box is provided in the box of the electrical equipment, and an equipment-side connector is provided in the connector mounting member. A cable-side connector of the cable is connected to the equipment-side connector, and a cable end portion of the cable is fixed to the box by a clamp member. As a result, the vibration that is transmitted to the cable can be matched with the vibration that is transmitted to the cable-side connector.

    摘要： To automatically prevent a reverse movement by inhibiting an excessive increase in an output torque of an electric motor.A means (31) calculates a target value for a rotation speed based on a command from a system (20), a means (32) calculates a deviation between a detection value from a rotation speed sensor (81) and the target value, a means (33) calculates a first target torque in a direction that the deviation will be eliminated, and a means (34) calculates, based on a command from the system (20), a second target torque in the same direction as the target value. A means (50) calculates a variation in a rotation angle of an electric motor (12) in a first range, and a means (60) calculates the same variation in a second range. A means (40) calculates, based on the variations from the means (50, 60), a third target torque in a direction that the rotation angle will return to a rotation angle before a predetermined time (t), and a means (73) limits the first target torque to one of the second and third target torques, said one target torque being in the same direction as the first target torque and being greater in absolute value. Substantially an entirety of the first range specifies a range for the variation in one direction, a remaining small range specifies a range for the variation in the other direction, substantially an entirety of the second range specifies a range for the variation in the other direction, and a remaining small range specifies a range for the variation in the one direction.

    摘要： A hybrid construction machine has an electric motor for driving the swing structure, and the electric motor is prevented from becoming incapable of generating torque due to a low energy state or an overcharged state of an electricity storage device. A swing-mode selector switch 77 which is manually operated switches between a hydraulic/electric combined swing mode for driving the swing structure by driving both the electric motor and a hydraulic motor and a hydraulic solo swing mode for driving the swing structure by driving only the hydraulic motor. For a normal operation, the swing mode is initially set in the hydraulic/electric combined swing mode. For a specific operation, the operator switches the swing-mode selector switch from a hydraulic/electric combined swing position to a hydraulic solo swing position.
