“…where u T is the signal produced by the torque regulator. Based on Equation (10) it is clear that the u T signal should be bounded (saturated) to not exceed the range from −1 to 1. This also allows for the implementation of a simple anti-windup filter.…”

The Synchronous Reluctance Machine (SynRM) is an electrical machine in which the useful electromagnetic torque is produced due to rotor saliency. Its high powerand torque-to-mass ratio and very good efficiency make it a cheap and simple alternative for permanent magnet or induction motors, e.g. in electromobility applications. However, because of magnetic nonlinearities, the rotational speed and torque control of a SynRM is a nontrivial task. In the paper, a control algorithm based on a Hamiltonian mathematical model is presented. The model is formulated using measurement results, obtained by the drive controller. An algorithm is tested in the drive system consisting of a SynRM with the classical rotor and a fast prototyping card. The drive dynamic response in transient states is very good, but the proposed algorithm does not ensure the best efficiency after steady state angular velocity is achieved.

“…Lightweight electric motors also reduce the overall weight of the vehicle and power consumption, thus improving vehicle performance [2]. Over the years, proven lightweight materials such as fiber-reinforced polymer, carbon fiber, and polymer composites have been used in various applications to enhance their efficiency [3][4][5]. They are being researched and implemented especially in the aviation field since weight is a very important factor here.…”

Electric motors are utilitarian devices of great potential as they can limit the amount of pollution by drastically reducing the release of harmful gases. The implementation of the right type of advanced materials plays a vital role in the amelioration of modern automobiles while maintaining and/or improving the performance and efficiency of the electric motor. The use of lightweight materials could result in a better-performing vehicle that can be much less heavy. The replacement of regular cast iron, steel, and aluminum with lightweight materials such as fiber-reinforced polymer, carbon fiber, and polymer composites can reduce the weight of the motor without impacting its performance and improve its energy-saving capacity. This paper explores a way to reduce motor weight by employing a PA6GF30 30% glass fiber-reinforced polymer casing to reduce the weight of the motor while making cooling system modifications. This material was applied to the motor casing, which resulted in a significant reduction in weight compared to the water-cooled electric motor of aluminum (Alloy 195 cast) casing.

“…These types of electric motor can be categorized into (i) surface mounted Permanent Magnet Synchronous Motor (SPMSM), (ii) Interior Mounted Permanent Magnet Synchronous Motor (IPMSM), (iii) Permanent Magnet Assisted Synchronous Reluctance Motor (PMASynRM) [6]. Among these types of PMSM, the PMASynRM has attracted a huge number of investigators to study the characteristics [6][7][8][9], apply optimization processes [10][11][12][13], and perform enhancement for different applications such as electric vehicular systems [4,[14][15][16]. Therefore, a large number of studies are devoted to introducing new branches of structural design for PMSM [4,15,[17][18][19][20][21][22].…”

On the Optimal Selection of Flux Barrier Reconfiguration for a Five-Phase Permanent Magnet Assisted Synchronous Reluctance Machine for Low-Torque Ripple Application

This paper aims to investigate the reconfigurations of rotor flux barriers for a five-phase Permanent Magnet Assisted Synchronous Reluctance Machine (PMASynRM). To precisely study the performance of the proposed configurations, a conventional PMASynRM with double-layer flux barriers is included in the study. Since the novel rotor schemes consume the same amount of rare-earth magnets, steel sheet materials, and copper wire, resulting in no extra manufacturing costs, the optimal reconfiguration should be determined, providing developed electromagnetic characteristics. Thus, all the proposed models are designed and analyzed under the same condition. The Lumped Parameter Model (LPM) is exported to the Finite Element Method (FEM) for precise analysis to reach developed torque and lower values of torque ripple. Based on the FEM results the model presenting the lowest torque fluctuations is selected as the optimal model and dynamically investigated. According to the results, in comparison with the conventional model, the introduced rotor designs provide a much lower value of torque fluctuations with a desirable amount of electromagnetic torque and power. In addition, the optimal model presents high values of power factor and efficiency, making it a vital alternative for low-torque ripple high-speed operations with no extra cost to the implementation process.
