SYSTEM AND METHOD FOR ALL ELECTRICAL OPERATION OF A MINING HAUL TRUCK
20230070784 · 2023-03-09 ·

A mining haul truck driven by electrical wheel motors is operated with all electrical power sources; that is, without a diesel engine. While travelling on the loading site, the mining haul truck is powered by an on-board energy storage system, which may include a bank of ultracapacitors. The mining haul truck then moves to the bottom of a trolley ramp and is coupled to trolley lines. While travelling uphill, the mining haul truck is powered by the trolley lines, and the on-board energy storage system is charged by the trolley lines. When the mining haul truck reaches the top of the trolley ramp, the mining haul truck is uncoupled from the trolley lines. While travelling on the unloading site, the mining haul truck is powered by the on-board energy storage system. The on-board energy storage system may also be charged by retard energy generated by the wheel motors during braking.

Method for controlling an electric motor
11682988 · 2023-06-20 · ·

A method is described for controlling an electric motor having a rotor. The method is carried out after a shutdown of the motor has been initiated. The method includes starting a timer in a motor controller, performing regenerative braking to recapture kinetic energy from the rotor as electrical energy, and using the recaptured electrical energy from the regenerative braking to power the motor controller. If the timer in the motor controller exceeds a predetermined timer value, a flag is set in memory in the motor controller to indicate that the motor has stopped.
