“…where 𝐼 and 𝐼 represent the current in the star and in the pe respectively. In order to obtain the same MMF from the two windings, the rela number of turns in the two windings was calculated as in (4) [20]. H volume and the copper losses were the same as in the conventional sta phase machine.…”

“…It was demonstrated that using a dual five-phase winding configuration connected in a combined star-pentagon reduces the losses of the induced eddy currents in the permanent magnets and in the rotor core while maintaining the five-phase terminals as in the traditional five-phase connections. The combined star-pentagon winding provides the required phase shift between the two windings (18 • ) to cancel all harmonics below the MMF component that generates the torque [20][21][22][23][24].…”

“…In [20], it was found that the output power of the five-phase induction machine with the combined star-pentagon winding with one phase opened was increased by about 16% compared to the star-connected winding. A dynamic and a steady state model for the combined star-pentagon winding were studied in [21,22].…”

Due to the significant advantages of a high torque density, better fault tolerance and high efficiency, the combined star–pentagon winding has recently gained researchers’ interest. In this paper, a simple method to identify the sequence of phases of a five-phase machine with combined star–pentagon winding was proposed. This was accomplished using resistance measurements between adjacent and non-adjacent phases. The analysis was conducted to clarify the phase sequence identification method. A case study of a 5.5 kW five-phase synchronous reluctance motor with combined star–pentagon winding was considered to simply apply the proposed method using an LCR meter for resistance measurements. The parasitic and wire resistances are dominant in the studied case, and this did not influence the accuracy of this method.

“…During the healthy situation, a five-phase machine with star-connected windings performs well, but the pentagon and pentacle are favored during the defective scenario [7]. Recently, a combined starpentagon configuration was shown in [8,9]. The combined star-pentagon design incorporates the benefits of both star and pentagon winding.…”

“…In [15,16], the performance of a fivephase SynRMs drive system based on a matrix converter was investigated at different loading conditions for both healthy and fault case. Different SynRM drive systems have been introduced in literature with either a three-phase or multiphase configuration and with conventional rectifier-inverters or with matrix converters [7][8][9][10][11][12][13][14][15][16]. The literature lacks the comparison between multiphase drives based on matrix converter and the conventional three-phase drives.…”

This paper compares and evaluates the cost, performance and reliability of three drive systems. The motor in these drive systems is a synchronous reluctance machine (SynRM). The first drive system (Drive-1) consists of a threephase SynRM fed from rectifier-inverter. The second drive system (Drive-2) consists of a five-phase star-connected SynRM fed from rectifier-inverter. The third drive system (Drive-3) consists of a combined star-pentagon SynRM fed from indirect matrix converter. It is found that the average torque of Drive-2 and 3 is 6.56% and 13.35% higher than Drive-1, respectively. Drive-1, 2 and 3 have torque ripples of 7.94%, 6.58%, and 5.52%, respectively. At rated condition, Drive-2 and 3 are 0.32% and 0.58% more efficient than Drive-1. In terms of cost, Drive-2 and 3 are only 2.44 %and 2.19% more expensive than Drive-1. Moreover, Drive-3 is the most reliable drive system and Drive-1 is the least reliable system.
