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.

“…This architecture includes a rapid rotor with permanent magnets (internal permanent magnets ring), a slow rotor with ferromagnetic pole pieces and a fixed permanent magnets ring (external permanent magnets ring) for each stage of magnetic gear, as shown in the Fig.2. A hybrid excitation synchronous generator developed by Jeumont Electric [11]- [12] is integrated in the conversion chain after the last stage of gear (Fig.1). This topology potentially offers high performance and must be strongly optimized to give a hope of competitiveness compared to indirect drive with mechanical gears and even for high torque applications (offshore wind turbine for instance) [13].…”

“…The generator studied in this article is a hybrid excitation synchronous generator developed by Jeumont Electric [11]- [12]. Considering the conversion chain presented in Table 4, the input torque of the generator depend on the gear ratio of the FMID − with stages ( = 1 or 2) (18).…”

International audienceThis article deals with the optimization of a full magnetic indirect drive (FMID) with magnetic gears which uses an analytical model based on subdomain resolution of Laplace's and Poisson's equations of the magnetic gear. A bi-objective analytical optimization is performed with a PSO algorithm with a minimization of the mass of the magnetic parts and a maximization of the gear ratio. This intermediate optimization is a step to optimize a 6MW FMID for a offshore wind turbine with one or two magnetic gears stages. It also compares FMID magnetic parts masses with a direct drive conversion chain with the same generator topology (hybrid excitation synchronous generator)

“…To make it easier to regulate the air-gap magnetic field of PMSMs, scholars proposed a hybrid excitation synchronous machine (HESM) that combined the PMSM with the electrically excited synchronous machine (EESM) after taking the efficiency and power density into account [5][6][7][8][9][10][11][12][13][14][15][16]. The HESM is capable of regulating the air-gap magnetic field, and both its efficiency and power density fall in between those of the PMSM and the EESM.…”

To facilitate the regulation of the air‐gap magnetic field of permanent magnet synchronous machines, a novel topology of a high‐speed hybrid excitation synchronous machine (HESM) was presented. The electromagnetic performance of the proposed HESM was evaluated. The air‐gap magnetic field regulation principle was introduced first. Then, a mathematical model of the HESM was established. Based on the characteristics of a 3D magnetic circuit, the HESM equalled three types of 2D magnetic circuit machines in axial parallel superposition, and thus the expressions of inductance parameters were deduced. Subsequently, the voltage regulation performance of the HESM was assessed according to the mathematical model and inductance parameters. The loss and efficiency were calculated. Finally, a HESM prototype was tested and verified.
