In a hydraulic drive system, which component is powered by a 3/8 hp motor?

Explanation:
In a hydraulic drive, motion is generated by a pump that moves hydraulic fluid under pressure. The 3/8 hp motor powers that pump, providing the force to pressurize the oil and drive the hydraulic cylinders that move the escalator or moving walk. The other items are not the moving part powered by the motor: platform control wiring is the electrical control circuitry, hoistway limit switches are sensors that stop or limit travel, and the hydraulic drive system is the overall arrangement, not a single powered component. So the pump motor is the part powered by the 3/8 hp motor.
