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.

This study presents a novel approach to the design process of a permanent-magnet flux-modulated machine by simultaneously focusing on the machine major advantage and disadvantage, that is, the high torque density and low power factor. The machine can be designed with a high power factor while retaining the high torque density. To do so, they both need to be described precisely. The torque equation is improved by considering the stator-winding leakage flux. It determines the relation between the geometric parameters and the torque more accurately. The power-factor equation is derived from the electric equivalent circuit representing the simplest description of the machine. The machine geometry optimised with the design of experiments via Taguchi methods assures the best possible performance within the set limitations. It is shown that using the proposed design process makes the permanentmagnet flux-modulated machine more appropriate than the classical synchronous machine for the direct drive applications requiring a high torque density, low weight and high efficiency.

This study proposes a new type of magnetic gear, namely, the electromechanical integrated magnetic gear, that integrates the traditional field-modulated magnetic gear, drive, and control. The topology and operating principle of the electromechanical integrated magnetic gear are described in detail in this article, and the constraints of parameter design and speed ratio of electromechanical integrated magnetic gear are presented. Moreover, magnetic field distribution is analyzed with the finite element method. Subsequently, the harmonics of the magnetic field and the electromagnetic torque are calculated. The static torques on all the components are exhibited by finite element method and torque test. The effects of the design parameters on the torques and the torque densities are discussed, and the results show that electromechanical integrated magnetic gear has a high speed ratio and can generate a high torque at low speed. The maximum torques are affected by air-gap thickness and other parameters.
