“…For an accurate estimation of magnet height Z hm , a 2D formulation that takes into account the interpolar flux leakages is used. Indeed, relation (6) is derived from a 2D model issued from solving the field equations by using the method of separating variables [29]. The calculation is performed considering an equivalent slotless linear generator.…”

This paper deals with the design and performance analysis of double stator axial flux permanent magnet generators for rim-driven marine current turbines (MCT). Indeed for submarine applications, drive train reliability is a key feature to reduce maintenance requirements. Rim-driven direct-drive multi-stator generators can therefore be a very interesting solution to improve this reliability. In this context, the presented work focus on the design of a double-stator axial flux permanent magnets (PM) generator as a rim-driven direct-drive multi-stator generator. The paper details the models, specifications and an optimization procedure that allow to preliminary design these kind of generators for rim-driven marine turbines. Thereafter, validations with finite elements computations and performance analysis considering particular design of rimdriven generators are presented. The obtained results highlight some designs issues of PM generators for rim driven marine turbines. In order to assess the effectiveness of the double stator axial flux PM generator, a comparison with a designed surface mounted radial flux PM generator for rim marine turbines is carried out.. The comparison highlights that the double stator axial flux generator presents a better cooling and a reduced active parts cost and mass than the radial flux PM generator.International audienceThis paper deals with the design and performance analysis of double stator axial flux permanent magnet generators for rim-driven marine current turbines (MCT).

By having accurate knowledge of the magnetic field distribution and the thrust calculation in linear synchronous motors, assessing the performance and optimization of the motor design are possible. In this paper, after carrying out a performance analysis of a single-sided wound secondary linear synchronous motor by varying the motor design parameters in a layer model and a d-q model, machine single-and multi-objective design optimizations are carried out to improve the thrust density of the motor based on the motor weight and the motor efficiency multiplied by its power factor by defining various objective functions including a flexible objective function. A genetic algorithm is employed to search for the optimal design. The results confirm that an overall improvement in the thrust mean, efficiency multiplied by the power factor, and thrust to the motor weight ratio are obtained. Several design conclusions are drawn from the motor analysis and the design optimization. Finally, a finite element analysis is employed to evaluate the effectiveness of the employed machine models and the proposed optimization method.

Permanent magnet linear synchronous motor (PMLSM) has important applications in transportation and industrial control systems for its direct thrust and high power density, etc. Thrust and normal force are the most important criteria for the PMLSM, and numerical methods and finite element analysis (FEA) methods have been conduced to evaluate the forces. In this paper, a prototype has been built to measure the thrust and the normal force of a PMLSM Through investigations with experiments, the traits of the thrust and the normal force have been found out, including the trends versus exciting currents with different amplitudes, different air gap lengths, variable magnetic poles, and different magnet arrangements. Conclusions are drawn through experimental analysis benefit to the electromagnetic design and control scheme evaluation for the PMLSM.
