“…The article proposes an innovative method that enables a reduction in reactive power and, consequently, reduces losses in the AC-PMSM system. There are solutions that reduce the reactive power when powering the PMSM from power electronic converters, but these involve complicated control methods or modifications to the motor's design [40,[49][50][51]. The control system presented by the authors of this work is simple and easy to achieve.…”

“…For speeds below the nominal speed ω < ω N , the current set in the d axis is equal to 0 (I d = 0) in order to maximize the torque [34,37,39]. For speed ω > ω N , it is possible to weaken the field by reducing the stator flux in the d axis in different ways (e.g., [40]) in order to operate above the nominal speed, but this case is not considered in this article.…”

The International Maritime Organization are introducing more and more stringent requirements concerning increasing ships’ energy efficiency. They are becoming a huge challenge for design engineers. This article proposes a method to increase the energy efficiency of mechatronic drive systems in ship systems via the use of highly efficient electric permanent magnet synchronous motors (PMSMs). An innovative control strategy is suggested. It is based on the modification of the classic PMSM control and ensuring energy optimization through a reduction in reactive power in the Active Converter–PMSM system. Analytical and simulation studies using the Matlab–Simulink program are presented. They confirm the possibility of reducing reactive power in a PMSM drive system. A verification of the results of analytical and simulation examinations was conducted at a laboratory station with the use of the Speedgoat module operating in the Rapid Control Prototyping mode. Both the simulation and experimental research results indicate the effectiveness of the proposed PMSM control method. This method has good prospects for application in energy-saving marine drive systems.

“…This can be seen in the comparison in Figure 4. The field currents can create variations in the efficiency map, where both the torquespeed curve is changed and the region of high efficiency is moved [46]. This can be seen in Figure 5.…”

“…Non-radial flux could then instead be between rotating discs, toroid shapes or spheres. Several concepts of hybrid excitation include machine types with different directions of the flux, such as the toroid versions of consequent pole machines by Spooner [135] and Aydin et al [142] and the disc machines by Eastham et al [175] and Yiping et [176], as well as the axial flux machines [46,[177][178][179]. Other non-radial flux paths with toroidial coils were studied by Kosaka [73].…”

Hybrid excitation is a technology that combines the advantages of field windings and permanent magnets for inducing magnetic flux. This article studies the benefits of hybrid excitation and provides an outlook on their possible applications, such as wind power generators and electric vehicle motors. Compared to permanent magnet-based machines, hybrid excitation gives a variable flux while still using the advantage of the permanent magnets for a portion of the flux. This article also looks into some different categories of machines developed for hybrid excitation. The categories are based on the reluctance circuit, the relative geometrical location of the field windings relative to the permanent magnets, or the placement of the excitation system.

“…As the main power supply device, a generator provides the needed electric energy to many types of electric equipment, except starter motors, and undertakes the function of charging the battery. Without generators, the advancement and comfort of modern vehicles is impossible [1][2][3][4]. With the development of vehicle technology, increasingly more types of electrical equipment are used in vehicles, which greatly increases electricity consumption.…”

Silicon rectifier generators, which are single-excitation generators, are commonly used in vehicles. However, a traditional single-excitation generator cannot satisfy the requirements of modern vehicles due to its low efficiency, high failure rate and large excitation loss; a hybrid excitation generator is more suitable for a wide range of applications in vehicles because of its many advantages. In this study, a novel, high-efficiency and energy-saving hybrid excitation generator with a claw-pole series magnetic circuit for vehicles was designed. The magnetic circuit and principle of operation were analyzed. The structure parameters of the hybrid excitation generator were initially designed according to motor design theory. The model of the hybrid excitation generator was built based on the finite element method, and the no-load characteristic was analyzed. Furthermore, the influences of the permanent magnet thickness and core slot width on the performance of the generator were analyzed. According to the results, the structural parameters were optimized. The no-load output characteristics and load characteristics were compared between the generator and a silicon rectifier generator, and the test results show that the design, simulation and optimization methods were reasonable. This provides theoretical support and research methods for the development of a hybrid excitation generator.
