Belparts Excavator EX600 slewing motor 4398514 0788801 swing motor assy for hitachi

From the perspective of system coordination, the swing motor needs to closely cooperate with the slewing bearing, hydraulic pump, and control system to form a complete swing operation system. As a key component connecting the upper body and the lower chassis, the slewing bearing transmits the rotating torque output by the motor to the entire upper body; the hydraulic pump continuously provides a high-pressure oil source for the motor, and its oil supply stability directly affects the operation smoothness of the motor; the control system (such as the operating handle and electronic control unit) accurately controls the start-stop, speed, and steering of the motor according to the driver's instructions. Only with the cooperative work of the three can the driver accurately control the swing action of the excavator to meet the needs of different operation scenarios.
