Torque Output
The travel motor is designed to provide a significant amount of torque. The torque output can vary depending on the operating pressure and the internal design of the motor. Typically, it can generate a continuous torque in the range of 1000 - 3000 Nm (Newton - meters). This high torque is essential for propelling the heavy weight of the excavator and for providing sufficient traction.
Peak Torque Capacity: In addition to the continuous torque, it has a peak torque capacity to handle sudden loads or difficult terrains. The peak torque can be around 3500 - 5000 Nm, allowing the excavator to overcome obstacles or operate under strenuous conditions.
Speed Range
Operating Speed: The motor has an operating speed range measured in revolutions per minute (rpm). The normal operating speed for the travel motor is usually in the range of 0 - 100 rpm. This speed range allows for precise control of the excavator's movement speed, from a slow crawl for precise positioning to a relatively faster speed for traveling across a job site.
Maximum Speed: The maximum speed the motor can achieve might be around 120 - 150 rpm, although this is often limited by the excavator's control system to ensure safe and stable operation.
Power Output and Efficiency
The power output of the travel motor is calculated by multiplying the torque and the rotational speed. Given the torque and speed ranges, the power output can vary from a few kilowatts to tens of kilowatts. The motor is designed to operate with a certain level of efficiency. The typical efficiency range is around 70 - 85%, which means that a significant portion of the input hydraulic power is converted into useful mechanical power to drive the tracks.
