Title:
SYSTEMS AND METHODS FOR OPERATING EXCAVATION MACHINES
Document Type and Number:
WIPO Patent Application WO/2023/192958
Kind Code:
A3
Abstract:
An excavation machine is provided. The excavation machine includes an excavation device and an excavation device drive system that powers the excavation device to move cutting tools, wherein the excavation device drive system includes an electric motor and a motor controller, wherein the motor controller is programmed to control the speed of the excavation device drive system. The motor controller sets the speed of the excavation device drive system at a predetermined excavation speed based on a predetermined target power, the predetermined target power being associated with a target torque generated by the electric motor. The speed of the excavation device drive system is set at a predetermined first excavation speed when a power transmitted to the electric motor is below the predetermined target power and at a predetermined second excavation speed to maintain the power transmitted to the electric motor at the predetermined target power.
