This paper discusses the design and testing of an aircraft electric fuel pump drive. The drive is a modular, four phase, fault tolerant system which is designed to meet the specification with a fault in any one of the phases. The motor employed has a permanent magnet rotor with the magnets arranged in a Halbach array to maximise the air-gap flux density. Exceptionally high electric loadings are obtained by flooding the entire motor with aircraft fuel, which acts as an excellent cooling agent Theoretical results are compared with test results gained in conditions approaching those found In an aircraft Tests are carried out on the un-faulted drive and with one of several fault scenarios imposed. The electrical and thermal performance of the drive is assessed, showing how the flooded fuel cooling has excellent performance without introducing significant drag on the rotor. (7 References).
