Core Performance Indicators of the Slewing Motor
The performance of the slewing motor directly impacts the excavator's operational capabilities. Key evaluation parameters include:
-
Rated Torque: Typically 1000~5000 N·m, determining the rotational driving force.
-
Maximum Working Pressure: Usually 30~35 MPa, affecting the motor's power density.
-
Displacement: Measured in mL/r; higher displacement increases torque but reduces speed.
-
Slew Speed: Normally 5~12 rpm; excessive speed causes inertial shock, while insufficient speed reduces efficiency.
-
To improve the energy efficiency and reliability of slewing motors, modern excavators employ the following advanced technologies:
-
Variable Displacement Control: Uses electro-proportional valves to adjust the swash plate angle, enabling automatic switching between high and low speeds for energy savings and power.
-
Lightweight Design: Utilizes high-strength aluminum alloy housings to reduce overall weight while maintaining structural integrity.
-
Smart Braking System: Integrates ECU control to achieve soft braking, minimizing hydraulic shock during stops.
-
Integrated Hydraulic Circuit: Incorporates anti-shock valves and make-up valves internally, reducing external piping and failure rates.
