Rated Pressure: The rated pressure of the swing motor is generally 20 - 30 MPa. Considering the working conditions and requirements of the SG025 excavator, the rated pressure of the E70B swing motor is likely to be around 25 MPa.
Peak Pressure: The peak pressure that the swing motor can withstand is generally 30 - 35 MPa, and the E70B swing motor may have a peak pressure of around 32 MPa.
Speed: The maximum rotational speed of the swing motor is an important parameter, which is related to the size and working requirements of the excavator. For the SG025 excavator, the maximum rotational speed of the E70B swing motor is estimated to be 10 - 15 rps (revolutions per second), that is, 600 - 900 rpm.
Torque: The output torque of the swing motor is an important factor in determining the working ability of the excavator's swing. The E70B swing motor needs to provide sufficient torque to ensure the smooth rotation of the excavator's upper body. The rated torque is usually in the range of 1000 - 3000 N·m. For the E70B, considering the tonnage and working conditions of the SG025 excavator, its rated torque is estimated to be around 1500 - 2000 N·m.
