When specifying components for a hydraulic power unit, the prime mover is sized based on torque, speed, and power requirements of the hydraulic pump. This is fairly straightforward for electric motors because they generally have a starting torque that far exceeds running torque. Often, though, designers specify motors sized larger than necessary.
