Abstract
A hydraulic motor drive system controls the pressure of the hydraulic fluid delivered to a motor by a variable pressure source to control the rotation of a high inertial load rotary member driven by the motor. The speed of the motor and/or rotary component is monitored and changes in the speed are controlled by changing the pressure of the hydraulic fluid delivered to the motor.
