Cogging Torque Definitions for Magnetic Gears and Magnetically Geared Electrical Machines
IEEE Transactions on Magnetics, 2018Although cogging torque in magnetic gears (MGs) has been studied, the additional degree of freedom inherent to MGs makes it unclear exactly what is defined as the cogging torque of a MG. Although MGs generally have relatively smooth torque transfer characteristics, this paper reveals that when the gear is used in an up-speed configuration, cogging ...

Coaxial Magnetic Gear Design and Optimization
IEEE Transactions on Industrial Electronics, 2017The 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.

Gearing ratios of a magnetic gear for marine applications
2009 IEEE Electric Ship Technologies Symposium, 2009Marine propulsion systems have become increasingly electromechanical in recent years. Proposed systems show increasing torque density in an effort to reduce volume and weight. A magnetic gear is proposed to reduce the size of the propulsion motor and achieve similar torque amplification provided by a mechanical gearbox, without the maintenance and ...

Gearing ratios of a magnetic gear for wind turbines
2009 IEEE International Electric Machines and Drives Conference, 2009The wind turbine industry is growing at an incredible rate as numerous governments demand an increase in renewable energy generation capacity. The great multitude of turbines on windfarms throughout the world range from ones which are controlled mechanically with gears to ones which are controlled with power electronics and no gears. A drivetrain for a

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 ...

IEE Proceedings B Electric Power Applications, 1980
The paper presents an appraisal of the problems inherent in the production of a magnetic gear. A new form of gear is presented, together with the theoretical basis of its operation, and is compared with a simple wheel gear. Experimental results are included for a complete gear and for the constructional elements.

2012 XXth International Conference on Electrical Machines, 2012
Linear magnetic gears, when coupled with a linear permanent magnet machine, are a high-efficiency, high-reliability and force-dense alternative to traditional linear actuation solutions. It is shown that the force density of a linear magnetic gear is affected by the required output stroke and gear ratio.

Magnetic Coupljng Studies Between Radial Magnetic Gears
1997 IEEE International Magnetics Conference (INTERMAG'97), 1997The 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 ...
