TORQUE OUTPUT CONTROL FOR SWING PUMP

摘要

A hydraulic circuit including a hydraulic swing motor having a first port and a second port. A first motor conduit connected to the first port of the hydraulic swing motor, and a second motor conduit connected to the second port of the hydraulic swing motor. The hydraulic circuit further includes a pump to selectively supply a flow of pressurized hydraulic fluid to the hydraulic swing motor through the first and the second motor conduits. A controller electrically connected to the pump adjusts a torque output of the pump based on a swing speed of the hydraulic swing motor.
