“…The Reluctance Magnetic Gearbox (RMG) is a radial magnetic gearbox with the inner rotor made of electrical steel and no magnets. Source: [21] The RMG has a rotor with magnets and a rotor made of electrical steel. The absence of magnets makes the inner rotor more robust and allows for higher speed since the mechanical issue of holding the magnets is removed.…”

This work proposes the use of a magnetic gearbox to be applied on an energy storage system based on flywheel to allow the use of a conventional electric machine external to the vacuum chamber as the primary machine, maintaining the possibility of using a rotating mass with high speeds. Parametric simulations were performed using finite element software to determine the behaviour of the various variables of the magnetic gear in terms of its performance and design constraints. Finally, a prototype was built to validate the simulations and the considerations made.

A high gear ratio flux switching permanent magnet machine (HFSPM) was proposed to improve the torque performance in flux switching permanent magnet machine (FSPM). Conventional FSPMs address flux bypass issue when designed with a high gear ratio. The HFSPM adopts a dual rotor structure to overcome this flux bypass issue. First, the cause and effect of flux bypass issue was discussed using a magnetic equivalent circuit (MEC). Further, the process of overcoming the flux bypass issue using dual rotor structure was discussed. An alternative HFSPM, consequent pole HFSPM (CP-HFSPM), was proposed to enhance torque performance. The CP-HFSPM was optimized for high torque performance and proper power factor.

“…Fig 1, shows the exploded conceptual structure of a conventional and RAMG. In [33] a radial flux reluctance MG is introduced and compared with traditional coaxial MG in gear ratio and torque transmission. A similar structure of reluctance MG is introduced in [34] using superconducting material in inner and outer rotor of coaxial structure with a single middle PM rotor to achieve a higher torque density in exchange of more cost.…”

This paper proposes modelling and optimization of a new reluctance axial flux magnetic gear (RAMG) with stationary outer rotor and advantages of lower permanent magnet usage. Due to the less use of the PMs, this structure has a higher economic interest, more reliability, and very simple and robust structure than its conventional ones. Gear ratio and operating principles are extracted and verificated using 3-D finite element method (FEM) simulations. Finally, a parametric optimization is done based on effective dimensions in design procedure with maximum torque density objective function. The magnetic flux distributions of optimized RAMG are calculated by 3-D FEM, as well as static and dynamic magnetic torques are derived correspondingly.
