This paper presents a state of the art of multiport machines and magnetic gears designed for power generation applications. A multiport machine consists mainly of an electrical machine wo which a magnetic gear is integrated. Thus, one can get a device with more than two shafts, capable to operate at different levels of torque and speed. The main structures found in the literature, their operation, speed increase capability, materials, advantages and disadvantages are depicted in this review-type paper.

“…CMG offers several advantages over mechanical gears, including a simplified structure, no friction, low noise, automatic overload protection and so on. They have broad application prospects in new energy vehicles, wind power, hydro power, and other industries [3]- [4]. Then, magnetic gears are also divided into planetary magnetic gears [5], harmonic magnetic gears, coaxial magnetic gears, and many other types [6].…”

Abstract-To enhance the output torque and minimize the torque ripple of coaxial magnetic gear (CMG), a novel auxiliary flux modulator CMG with unequal magnetic poles is proposed. This design incorporates an inner rotor with an asymmetric sector and a trapezoidal combined N-S pole structure, featuring Halbach arrays for the arrangement of permanent magnets (PMs). The outer rotor PMs adopt a Spoke-type configuration. To optimize the CMG for high output torque and low torque ripple, a sensitivity analysis is conducted to identify key size parameters that significantly influence the optimization objectives. Based on the sensitivity hierarchy of these parameters, a multi-objective optimization analysis is performed using a genetic algorithm (GA) to determine the optimal structural parameter values of the CMG. In addition, a coaxial magnetic gear (CMG) topology with 4 inner and 17 outer pole pairs is adopted, and the parametric model is established. Finally, the electromagnetic properties of the CMG are evaluated using the finite element method. The results indicate a remarkable reduction in torque ripple, specifically by 46.15%.

“…In [48] and [49] the 1 st and 2 nd stage of an CMG for a Marine Hydrokinetic Generator (MHG) are presented. The magnetic gearbox is designed for 5 kW input at 40 rpm, and the 2-stage design is chosen to obtain a total gearing ratio of 1:63.3, hence quite high compared to other single stage CMG that have been demonstrated.…”

“…In Fig. 1.12 the initial idea of implementing the generator into the 2 nd stage gear is illustrated, however, in [49] it is made clear that there is not enough space and that a separate generator is needed. This makes a direct comparison between the two solutions difficult but if the torque density of the two-stage gearbox is calculated from the combined volume of the two CMG stages and the stall torque of the 1 st stage, a theoretical torque density of 260 Nm/l is obtained.…”
