Synchronous Reluctance (SyR) machines are a viable alternative to other kinds of electrical machines in many fields. The simple rotor structure allows a high efficiency level with low manufacturing costs and higher safety in high-speed operations. However, one of the main problems of the SyR machines is the torque ripple generated by the interaction of the stator and rotor Magneto-Motive Force harmonics. Many design solutions have been proposed to date, but heavy torque ripple reduction has only been achieved with long optimizations runs or with complex machine structures. This paper presents an easy and effective method to reduce torque ripple through flux barrier shift. Two machines were designed in order to compare the proposed design with a state-of-the-art procedure. The machines designed with flux barrier shift presents similar performances to the optimized machine, with a lower design time and a more general design method.

This paper proposes the analysis tools, the methodology, and the experimental setup to support the characterization of vibrations in linear switched reluctance actuators by analyzing the audio signals emitted. The analysis is performed by using two approaches: the windowed Fourier transform and the joint wavelet-Fourier which leads to a hybrid spectrum representation. The spectrum of the audible noise from the vibrations is characterized for different configurations of the actuator, and the spectral components are presented, analyzed and discussed. To evaluate the responses for these configurations, one uses either its frequency components, the spectral cross-correlation, and the Cross-Power Spectrum Density through the Welch periodogram. The reliability and the suitability of this approach are verified by comparing the experimental data with the outcomes from finite elements simulations. The proposed method enables the experimental identification of the critical vibration frequencies in LSRA.

This paper investigates two design topologies of three-phase switched reluctance machines, i.e. first one with twelve stator poles and eight rotor teeth (12/8), the second one with twelve stator poles and sixteen rotor teeth (12/16), both intended for use as direct-driven generators in micro-wind energy conversion systems. The comparative design analysis is carried out by means of finite-element magnetic field analyses and dynamic simulations for generator output performance evaluation. Finally, a 1.5 kW-output-power three-phase 12/8 switched reluctance generator has been optimally designed and built for low-speed micro-wind power applications.

This paper presents an approach to construct an analytic model of Switched Reluctance Machine (SRM). This approach combines two techniques of Fourier and polynomial approximation for describing the nonlinear characteristics of SRMs, flux-linkage characteristic and torque characteristic. The Fourier approximation is applied for the periodical relationship of rotor position, whereas the polynomial approximation is applied for the nonperiodical relationship of current or flux-linkage. The combined Fourier-polynomial approximation technique leads to a simple formulation of the torque calculation derived from the proposed flux-linkage analytic model. This paper also introduces a method to minimize the number of Fourier coefficients by considering the odd-even property of the SRM characteristics. By this method, the spared number of model coefficients can be better utilized for increasing the harmonics and polynomial order of the model in order to enhance the accuracy. The validity and accuracy of the proposed model are evaluated by comparing the proposed model with the measured SRM characteristics. The evaluation results show that the proposed model is accurate and can be used for analysis and study of behaviours of SRMs.

In an effort to reduce weight and cost of directly - driven wind generators in the 3 MW, 11 rpm range, the paper introduces, “as improved”, an axial - airgap spoke - PM rotor three phase transverse - flux generator with two dual - core circular shape coils per phase and 3 rotors on same shaft. For optimal design - with a unique multi - dimensional objective function including active materials, capitalized losses, costs, inverter kVA costs plus over temperature and demagnetization avoidance constraints, a 3D nonlinear magnetic equivalent circuit (MEC) is used, to keep the optimization design computation time low. Key FEM validations - related to airgap flux density torque production, torque pulsations, inductances - are offered by a surrogate 2D FEM methodology based on a linear sectorial virtual motor model. Results for 3 MW, 11 rpm, reveal a 30% total (global) objective (cost) function reduction by optimization design for an efficiency of 96.69% power factor cosφ=0.665 at 1 total active materials (copper, laminations and PMs) mass of 9345 kg. the results are very promising in comparison with existing regular such PMSGs potentially allowing, in addition, increased voltages up to 20-30 kV per phase with cable - made stator coils, avoiding the voltage matching transformer towards local power grid.

A method for detecting inter-turn short circuit in the rotor field winding of a large hydro generator is presented. The proposed method is based on the use of two inductive probes installed at two different locations in the machine, exploiting therefore the existing magnetic symmetry. This latter consists of monitoring the algebraic sum of the two induced voltages of these two probes. The studied hydro generator has a rating of 310 MVA with 408 slots and 56 poles. Many advanced electromagnetic simulations based on finite element method were carried out in order to validate the proposed approach. The simulation results were compared to the experimentally measured data collected of the considered generator and obtained respectively at no-load and rated load.

This work presents a rigorous approach to simplify the design optimization process for Switched Reluctance Machines. First of all, the dimension of the Design Space is found to be equal to twelve, as the number of Independent Design Variables. Then, constraints and requirements in the design are represented as inequalities to determine the limit surfaces, which are nothing else than the boundaries of the Design Space. By applying constraints and requirements one by one, the paper shows how it is possible to find the Actual Design Space, which includes only feasible solutions to the design problem. A case study clearly shows how, by means of this methodology, the size of the Design Space can be decreased by orders of magnitude.

This paper presents and assesses the cooling integration of electrical machines with concentrated windings. A conventional coil in a concentrated winding with forced cooling applied on the exterior coil surfaces is replaced by an alternative solution where the coil is opened up in a laminar structure with the intention of the coolant fluid penetrating the coil and removing the interior heat. This is a purely theoretical study where a set of FE models are used to evaluate the torque capability under elevated thermal loads, comparing conventional to alternative cooling integration topologies. The objective of the unsophisticated FE evaluation models and simple design rules is to demonstrate the potential of the laminated type of windings where the space between the current carrying flat conductors is used to circulate coolant so that the heat losses are removed in the vicinity of where they are generated. Conjugate heat transfer analysis in Comsol multiphysics based on 2D and 3D is used to demonstrate the cooling capability for air and oil cooled windings up to thermal loads corresponding to 50 A/mm2at 24 nΩm and a target hot spot temperature of 120°C for copper.

This paper presents the design of a switched reluctance motor (SRM) for the traction motor of a forklift application. Design constraints and input parameters are defined according to the specifications of a forklift traction motor. Three-phase induction machines are commonly used for forklift propulsion systems. Several SRM configurations with higher number of rotor than stator poles are designed in order to compare their characteristics and capabilities. These configurations are 12/16, 12/20 and 18/24, and they are compared in terms of average torque, weight, RMS torque ripple, efficiency and temperature rise. Initial designs are obtained by basic analytical sizing equations. Optimization of initial designs is performed using combined analytical-FEA approach and genetic algorithm control optimization. Optimization goal is to achieve the design with the lowest volume and mass to increase torque density (torque/volume) and specific torque (torque/mass). The results show that 12/16 SRM is a suitable configuration for the forklift propulsion application due to its higher torque density.
