Fractional-slot concentrated-winding (FSCW) synchronous permanent magnet (PM)
machines have been gaining interest over the last few years. This is mainly due to the …

To achieve benefits similar to those seen in hybrid‐/all‐electric ground‐based and marine
vehicles, electric propulsion has been proposed for large commercial aircraft. Among the …

The idea of electric propulsion for transportation is not new; indeed, the first cars, nearly 200
years ago, were electric. However, our dependence on fossil fuels over the last 100 years is …

This paper presents an overview of motor drive technologies used for safety-critical
aerospace applications, with a particular focus placed on the choice of candidate machines …

Although the concept of variable-speed drives, based on utilization of multiphase machines,
dates back to the late 1960s, it was not until the mid-to late 1990s that multiphase drives …

Multiphase drives offer enhanced fault-tolerant capabilities compared with conventional
three-phase ones. Their phase redundancy makes them able to continue running in the …

Synchronous permanent magnet (PM) machines have been gaining a lot of interest over the
years. This is due to their several advantages including high power density, high efficiency …

The winding copper loss can be significantly increased due to skin and proximity eddy
current effects. The skin and proximity losses due to fundamental frequency current has …

This paper analyzes rotor eddy-current loss in permanent-magnet brushless ac machines. It
is shown that analytical or finite-element techniques published in literature for predicting …

In this paper, the main design characteristics of a scaled-size prototype of an integrated
generator for More Electric Engine application are presented. The reference electrical …
