“…The electric machines used for the propulsion have to offer high efficiency, high power density and maintenance-free operation. To achieve these goals, numerous research studies have been conducted on various electrical motors topologies associated with power electronics drives as well as conventional wound field synchronous machines (WFSMs), permanent magnet synchronous machines (PMSMs), induction machines (IMs) and unconventional permanent magnet structures [2][3][4][5][6][7][8][9][10][11][12][13][14].…”

The low speed toothed doubly salient permanent-magnet (TDSPM) machine is an interesting candidate motor for electric ship applications because, of its high torque output, maintenance-free operation and flexible working modes, which gives the opportunity to increase system’s reliability, and decrease the system size, weight and noise which are key features for naval applications. However, particularly in the 3-phase configuration, the stator and rotor saliency of these machines leads to a high level of torque ripple. To overcome these drawbacks, the use of polyphase machines (with a number of phases greater than three) can be a relevant solution. In this paper, an optimal design of two kind of novel 4-phase motors is performed in order to fulfil the specifications of a high power naval ship propulsion. The designs aim to maximize the torque to mass ratio. The motors’ performances are directly linked to their structural parameters, so, the impact of the coil number in terms of mean torque, torque ripple, energy ratio values, and efficiency is also presented and analysed. The design of these two electromagnetic structures, as well as the determination of their electromagnetic performances, are carried out using a particle swarm optimization algorithm (PSO) with taking into account thermal constraint. The performance of the proposed machine in terms of mean torque, torque ripple, energy ratio, and efficiency values is presented and analysed. The results obtained reveal that the TDSPM machines with four poles/phase are good candidates to meet the requirements of high power direct-drive ship propulsion system.

“…Since the machine has a high saturation, the inductance varies little according to the rotor position θ; this generates a low reluctance torque value [2,9].…”

“…These types of speed adaptation system have several disadvantages; for example, they are bulky, costly, and require regular maintenance. To overcome these problems, new structures of variable reluctance machines, operating at low speeds, called slow machines or direct attack machines are proposed [1][2][3][4][5][6][7][8][9][10]. One of these structures, named Doubly Salient Permanent Magnet Machine (DSPM), a variable reluctance machine, with a large number of rotor and stator teeth excited by non-rotating permanent magnets housed in the stator yoke, attracts more and more attention [2,9,13].…”

The aim of this work is to reduce the torque ripple of a low-speed/high-torque Doubly Salient Permanent Magnet (DSPM) generator for wind turbine applications. To do this, a combined design and control-based approaches are set up to improve the overall machine performance. The design-based approach helps to develop a form of small stator/rotor teeth combination, focusing on the shapes and dimensions of the teeth that will minimize torque ripple. On the other hand, in the second approach, a control technique is designed. It employs indirect torque control (Torque Sharing Function: TSF), including a PI-controller with gains adjusted continuously for regulating the reference current. The obtained results show that by combining these two approaches, the ripple rate of the electromagnetic torque for the studied DSPM is reduced to a minimum when the teeth shapes are trapezoidal in both the stator and rotor, and the command approach also allows an improvement in the total torque shape, such that the ripple rate decreases by about 96%.

“…Mobility, transportation, logistics, construction, production, agriculture, food, automation, and basically, any economical activities and industries directly or indirectly depend on rotating electrical machines [4][5][6]. The rapidly evolving industries have suggested that we will be witnessing further increase this rate [7][8][9][10][11][12]. Furthermore, the increasing demand for the hybrid and electric vehicles, the rapid transition toward automated systems and micro and nano mechatronics devises, increasing interests for more efficient energy conversion systems, and emerging new robotics machines have been motivating further advancement in the rotating electrical machines [13][14][15][16][17][18].…”

Primary importance is devoted to Fault Detection and Diagnosis (FDI) of electrical machine and drive systems in modern industrial automation. The widespread use of Machine Learning techniques has made it possible to replace traditional motor fault detection techniques with more efficient solutions that are capable of early fault recognition by using large amounts of sensory data. However, the detection of concurrent failures is still a challenge in the presence of disturbing noises or when the multiple faults cause overlapping features. The contribution of this work is to propose a novel methodology using multi-label classification method for simultaneously diagnosing multiple faults and evaluating the fault severity under noisy conditions. Performance of various multi-label classification models are compared. Current and vibration signals are acquired under normal and fault conditions. The applicability of the proposed method is experimentally validated under diverse fault conditions such as unbalance and misalignment.
