Coaxial Magnetic Gear Design and Optimization

IEEE Transactions on Industrial Electronics, 2017
The main aim of this paper is the imposition of constraints for the multiobjective optimizations of magnetic gears. In order to reduce the computational effort, a semianalytic design procedure is adopted, providing a fast simulation tool that can be embedded within an optimization loop.

A new magnetic gear using permanent magnet

IEEE Transactions on Magnetics, 1987
This paper describes the structure and the performance characteristics of a magnetic gear using SmCo 5 for the permanent magnet. The magnetic gear has a gear ratio of 1/3 and the maximum transmitted torque is 5.5 Nm at the driven magnetic gear. When the rotating speed of the driving magnetic pinion is 2000 rpm, the driven magnetic gear rotates at 2000 ...

Magnetic gear: A review

2014 11th IEEE/IAS International Conference on Industry Applications, 2014
This paper aims to present the operation principle of the magnetic gear by the finite-element method (FEM). The effect of the modulation phenomena is explained using the Coaxial Magnetic Gear as reference. The approach consists basically in obtaining the flux densities waves for the machine air gaps and then analyzes its harmonic spectra. Additionally,

The Cycloid Permanent Magnetic Gear

IEEE Transactions on Industry Applications, 2006
This paper presents a new permanent-magnet gear based on the cycloid gearing principle. which normally is characterized by an extreme torque density and a very high gearing ratio. An initial design of the proposed magnetic gear was designed, analyzed, and optimized with an analytical model regarding torque density.

Adjustable magnetic gear

Russian Electrical Engineering, 2017
A mathematical interpretation of a combined electromechanical device possessing the properties of a synchronous machine connected to a frequency converter and of a magnetic gear with a variable reduction factor is considered. The stator winding of the synchronous machine is concentrated (tooth winding), and its spatial period covers the full number of ...

VII.High-Efficiency Magnetic Gear and Developing Magnetic-Geared Motor

2016 International Conference of Asian Union of Magnetics Societies (ICAUMS), 2016
Magnetic gears can transmit torque without any mechanical contacts. Hence, they have low vibration, no wear and fatigue, which offer maintenance-free operation. Various kinds of magnetic gears have been introduced in previous papers and patents. Among them, a flux-modulated type magnetic gear, which consists of an inner and outer rotor with surface ...

Magnetic Coupljng Studies Between Radial Magnetic Gears

1997 IEEE International Magnetics Conference (INTERMAG'97), 1997
The torque of a magnetic gear system with different magnetic poles has been investigated by computer-aided simulation with 2 dimensional modeling processes of finite element analysis. With a fixed separation of distance, the torque shows a maximum for a special number of poles, which shifts to a higher number of poles as the ratio of the radius to the ...
