104-6485-005 Hydraulic Motor
| Theoretical Displacement | ~250 cm³/rev (cubic centimeters per revolution) | Displacement = volume of oil required to rotate the motor 1 full turn; higher displacement = higher torque at lower speed. |
| Maximum Continuous Pressure | 28 MPa (4060 psi) | Safe long-term operating pressure (inlet pressure); exceeding this causes seal damage and internal wear. |
| Maximum Back Pressure | 3 MPa (435 psi) | Maximum allowable pressure at the motor’s oil return port; use a relief valve if back pressure exceeds this value. |
| Rated Speed | 50 – 500 rpm | Optimal speed range for high torque output (≥90% of rated torque) and low noise; unsuitable for high-speed applications (e.g., >600 rpm). |
| Maximum Torque (Continuous) | ~10,500 N·m (7,740 lbf·ft) | Torque = (Displacement × Pressure × Efficiency) ÷ (2π); this motor delivers high torque for heavy-load scenarios (e.g., lifting excavator buckets). |
