“…Therefore, a multiobjective optimization algorithm is needed to solve the aforementioned optimization problem. The multiobjective optimization based on one-criterion Nelder-Mead method which is a ready-to-use function in MATLAB package was coupled with the FE model of the EMMS [21]. The objective function (F) is formulated as follows.…”

Cyclic loads such as weaving looms have an oscillating load torque profile which negatively affects the motor size and power consumption. In this paper, a novel electric motor with an integrated magnetic spring (EMMS) is proposed for cyclic loads. The magnetic spring provides the majority of the oscillating part of the load torque in a passive way, thereby reducing the power consumption. Besides, the design and analysis of the proposed EMMS are investigated for a weaving loom application. Moreover, the optimal design of the EMMS is manufactured and various measurements are obtained to validate the principle of the EMMS. It is found that the EMMS can effectively deliver about 40% of the load torque in a passive way. Interestingly, the amount of the delivered torque by the magnetic spring depends on the design choice. For a given load torque, the higher the part of the torque delivered by the magnetic spring is, the lower the power consumption from the supply will be. However, this increases the manufacturing cost of the EMMS. Therefore, the torque of the magnetic spring is a design choice that is a compromise between the investment cost of the EMMS and the total cost of ownership.

“…Optimal design for electric machines based on finite element magnetic simulation consumes a lot of time, therefore, choosing a suitable optimization technique is necessary to obtain an optimal design for the electric machines with a reduced time computation [25]. Multi-objective optimization or Pareto optimization has proved its efficient in different electrical machine design [26][27][28]. Nelder-Mead method presented in [28] is a multi-objective optimization based on a single criterion method.…”

This paper investigates the performance of 3-phase synchronous reluctance machines (SynRMs) when upgrading their stator to 5-phase, keeping the same rotor. The design of the 5-phase stator has been optimized to select the optimal dimensions of the slots and teeth. Moreover, a combined starpentagon winding is employed to further improve the machine performance. Different winding configurations have been studied and compared using 2D Ansys Maxwell transient simulations. It is observed that at optimal current angle and rated current, the average torque is increased by 17.41% when changing the 3-phase stator with the proposed 5-phase one. In addition, the efficiency of the 5-phase SynRM is increased by about 0.8% compared to 3-phase SynRM. At 3 times the rated speed, the torque and efficiency are significantly increased by around 33% and 3.5% respectively. Moreover, the 5-phase SynRM shows a superior performance in the faulty case with one phase opened. It works at 98.84% of the rated torque of the healthy 3-phase machine, whereas the 3-phase machine works at only 43.35% with huge torque ripple (228%). Finally, an experimental validation using the reference 3-phase machine has been done.

“…All of these algorithms can be applied using name-plate or load data during the operation of transformer without having to disconnect the transformer for testing purposes. Moreover, these algorithms can estimate three-phase transformer parameters as well as those of single-phase transformer [27], [28] and for optimal design of a three-phase high-speed flux reversal machine in [29].…”

In this work, the Coyote Optimization Algorithm (COA) is implemented for estimating the parameters of single and three-phase power transformers. The estimation process is employed on the basis of the manufacturer's operation reports. The COA is assessed with the aid of the deviation between the actual and the estimated parameters as the main objective function. Further, the COA is compared with well-known optimization algorithms i.e. particle swarm and Jaya optimization algorithms. Moreover, experimental verifications are carried out on 4 kVA, 380/380 V, three-phase transformer and 1 kVA, 230/230 V, single-phase transformer. The obtained results prove the effectiveness and capability of the proposed COA. According to the obtained results, COA has the ability and stability to identify the accurate optimal parameters in case of both single phase and three phase transformers; thus accurate performance of the transformers is achieved. The estimated parameters using COA lead to the highest closeness to the experimental measured parameters that realizes the best agreements between the estimated parameters and the actual parameters compared with other optimization algorithms.INDEX TERMS Coyote, PSO, Jaya, single-phase transformer, transformer equivalent circuit.
