“…The MRC motor is a novel motor that can perform energy conversion without iron cores (magnetic cores) (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13) , and its operating principle combines the energy transfer technologies of MRC and induction motors. Basically, an induction motor transmits energy through the electromagnetic induction between a primary side and a secondary side through an air gap.…”

“…Kurs et al proposed a novel technology that can transfer electromagnetic energy between two separated coils via electromagnetic resonance coupling (1) . Moreover, Sakai et al (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13) proposed a novel motor in which energy is converted through MRC between the three-phase windings of a stator and a rotor, and they also used the conventional induction motor technology.…”

In this paper, we propose a design method for a novel motor using magnetic resonance coupling (MRC) to enable the practical use of electric aircraft. The proposed motor can transfer electrical energy between a stator and a rotor via MRC, which does not require magnetic cores, thus realizing an ultralightweight design. Moreover, we detail the operating characteristics of the proposed motor and its equivalent circuit, analysis, and experiments. From the analysis, we clarify that the proposed MRC motor has a sufficient strength at an ultrahigh speed, and we describe its essential characteristics and the usefulness of its equivalent circuit. Further, our analytical and experimental results confirm that the proposed MRC motor can transfer electrical energy between a stator and a rotor, thereby generating torque.

Routing is the core of wireless sensor network deployment. This paper points out the research focus of the wireless sensor network transmission path and discusses the optimization problem of the transmission based on grid model. In this paper, routing attribute table that is maintained by the nodes, the density and relative distance of node distribution, is used to determine the clustering method. At the same time, the developed algorithm combines the relative position of the cluster and the base station to further improve the routing method of the sub-cluster head, Finally, the algorithm analyzes the influence of different parameters on the transmission path, and use the simulation experiments to evaluate the conclusions.

“…The same concept has recently been proposed for a highspeed, air-cored IM in [6], [7] and [8]. The results in these papers, however, are only based on 2D steady-state FE simulations at different stator frequencies and slip values for a given machine, and do not provide any insight into the optimal values of stator and rotor capacitors as a function of the machine parameters and operating conditions.…”

The performance of a high-speed air-cored induction machine (IMs) using capacitors to provide resonant operation is analyzed in this paper. Resonance can be obtained using the stator and rotor capacitors appropriately tuned with the machine inductances, though alternative options may be considered instead of rotor capacitors. The aim is to develop a simple analytical model for air-cored resonant induction machines and to use this to obtain an understanding of the operating principles and the limitations and issues. The analysis is based on the classical IM equivalent circuit supplemented with stator and rotor capacitors and considers different control scenarios to derive key expressions for resonance conditions, capacitor values, peak torque and efficiency and related slip values. The aim of this paper is to provide a full understanding of air-cored resonant IMs to assess the practicality of these machines.
