Magnetic gears

HOME / Applications / Magnets & Magnet Arrays / Magnetic gears

In this application note, two external magnetic gear systems with parallel axes will be studied [1],[2]. The analyzed magnetic gears are made of two different shapes: radial and parallelepiped permanent magnets.

Eddy current coupler is a non-contact coupling system that works on the Eddy current principle, where a circular electrical current is induced within a conductor by a nearby varying magnetic field.

Magnetic gears (MG) which achieve contactless power transmission are increasingly attracting the interest of industry. Traditional mechanical gears suffer from several weaknesses: friction losses, lubrication issues, heat, vibration and noise. Magnetic gears are therefore developed to overcome the issues accompanying the use of traditional mechanical ones.
