Aerospace series. AC induction electric motor driven, variable delivery, hydraulic pumps. General requirements. | Status: Current, Under review

1 Scope This document establishes the general requirements for electric motor driven, variable delivery, hydraulic pumps suitable for use in aircraft hydraulic systems. This document includes the general requirements for Alternating Current (AC) induction electric motor powered units. The AC power electrical power supply can be either controlled to provide a Constant Frequency (CF) or uncontrolled to provide a Variable Frequency (VF) AC supply to the electric motor. This document is intended to be used in conjunction with the detail specification that is particular to each application.
