Integrated full electric propulsion (IFEP) systems provide both ship propulsion and services with different electrical ratings. Instead of using multiple electrical machine sets, a dual wound machine with two sets of windings sharing the same stator slots can use one prime mover to provide two independent power supplies, achieving a more compact design and maximizing the power density. In order to provide independent power supplies, the windings must eliminate the electromagnetic coupling between them. A 2-pole and 6-pole dual wound machine has been designed previously. The simulation results show that there is no electromagnetic coupling considering the windings in the slots. It is important to investigate if there is any electromagnetic coupling caused by the end-windings. This paper proposes a simplified 2D and 3D end-winding model to analyse the magnetic field distribution and induced voltage using the Biot-Savart law. It is concluded that the end-windings of the dual wound machine are also not electromagnetically coupled, which proves that it is able to produce two independent power supplies for ship propulsion and services.

This paper presents findings from a combined theoretical and computational thermal analysis of alternative heat removal concepts for an open-frame PM machine. The analysed machine design has been developed for propulsion of an unmanned aerial vehicle (UAV), which operates in a regime characterised by a high torque overload ( 2.5) at take-off and a high efficiency (+95%) at high-altitude cruise operation. The thermal management of such a machine has a significant impact when balancing the design for a lightweight/compact solution. Here, direct air-cooling of the machine is analysed by focussing on the winding body that is the dominant heat source during the UAV’s take-off phase. As the airflow into the machine body is generated by the forward motion of the UAV, a careful consideration needs to be taken when guiding the air through the machine body. In this analysis, alternative airflow channelling via the stator-winding assembly is investigated. The results suggest that the proposed motor design with reduced conductor slot utilisation and stator bore airflow guiding feature allows for achieving the required convection heat transfer coefficient (75W/m 2 K at 1m/s), which is 150% improvement as compared with a more conventional design with a good conductor slot utilisation. However, the reduced conductor volume needs to be compensated for by appropriately adjusting the machine outer diameter and profile during the initial design sizing exercise.
