“…If the motor operates at zero-or low-speed range and the frequency of the injected signal is high enough, the component of back-EMF, the rotating and resistance voltage drops are considerably small and can be neglected [22], [29], [39]. Consequently, the HF mathematical model can be expressed as…”

Compared with the conventional three-phase motor, the five-phase interior permanent magnet synchronous motor (IPMSM) has better advantages on fault-tolerance due to redundant freedom. In order to obtain further fault-tolerance, this paper proposes a new high frequency (HF) signal-injection-based sensorless control strategy for five-phase IPMSM drives. The key is to extend the position sensorless technology based on HF signal injection into the five-phase motor control system, especially proposing a sensorless control method by injecting a HF square-wave voltage signal into the third harmonic space. The induced HF current responses in the third harmonic space can be utilized to track the rotor speed and position accurately. Compared with the conventional HF sinusoidal signal injection methods, the proposed method can effectively reduce the influence of digital filters, such as time delay and decreased performance because the low-pass-filter (LPF) is removed. In addition, the torque ripple caused by the proposed injection method in third harmonic space is reduced compared with the method in fundamental space. The effectiveness of the proposed method is verified by simulation and experimental results. INDEX TERMS Sensorless control, five-phase interior permanent magnet synchronous motor, third harmonic space, HF square-wave voltage injection (HF-SVI).

“…Thanks to the high steady-state performance of FOC, the general trend toward other methods has not yet been dominated. The precise control method, low torque ripples, and the constant switching frequency of FOC still draw the researchers' attention [122]. FOC is more popular in the area, such as the mining and steel industry, where the need for efficiency and better steady-state response is preferred to transient response.…”

Recent studies show that synchronous reluctance motors (SynRMs) present promising technologies. As a result, research on trending SynRMs drive systems has expanded. This work disseminates the recent developments of design, modeling, and more specifically, control of these motors. Firstly, a brief study of the dominant motor technologies compared to SynRMs is carried out. Secondly, the most prominent motor control methods are studied and classified, which can come in handy for researchers and industries to opt for a proper control method for motor drive systems. Finally, the control strategies for different speed regions of SynRM are studied and the transitions between trajectories are analyzed.

“…Up to now, synchronous permanent magnet motor (PM-SynM), synchronous reluctance motor (SynRM) and synchronous reluctance motors assisted by permanent magnet (PMa-SynRM) (this last one with different types of magnets) have being developed [5][6][7]. None of these motors has starting torque and its use is appropriate to drive centrifugal pumps and fans that work at variable speed to control flow and for which variable frequency drives (VFD) are used.…”

“…The VFD also allow starting these machines [8]. In the case of constant loads, with the aim of not using VFD or soft starts that are expensive equipments, variants such as the direct start to the line with a synchronous reluctance motor (DOL SynRM) [6], or with direct start to the line using a modified PM-assisted reluctance synchronous motor (DOL Start PMa-SynRM) [9][10], are possible solutions. This paper presents, firstly, a summary of the constructive and operational characteristics of a PMa-SynRM, with different types of PM; and afterwards, those characteristics of the DOL Start PMa-SynRM.…”

For driving constant loads in industry, the use of direct-on-line-start permanent-magnet-assisted synchronous reluctance motors with ferrite magnets (DOL-Start-PMa-SynRM) is proposed. The bibliographic search demonstrated that this new motor has greater efficiency than one similar induction motor (IM). It was evidenced that the main element that is required for direct starting is to insert a squirrel cage into the rotor of a PMa-SynRM, which does not produce negative operational effects in a steady state. An economic evaluation was carried out in a sugar mill company, applying the differential net present value (NPV) method, and a sensitivity analysis, considering the four factors that present the most variation. It was demonstrated, by means of a Pareto diagram standardized for the NPV that the most significant factors are fuel factor, lifespan and the multiplication of both. With response surfaces that are obtained with a multilevel factorial experiment, it was determined that, by varying the factors in the ranges considered, the NPV always remains positive and higher than 2200 USD. This is mainly due to the notable difference between the efficiency of the DOL-Start-PMa-SynRM and that of the IM. Consequently, is proved that an investment in the DOL-Start-PMa-SynRM may be feasible.
