Torque determination for a cylindrical magnetic clutch

Calculation features of magnetic coupling in non-magnetic structures

“…In them, the magnetic field is created by permanent magnets (NdFeB and SmCo) installed in the leading and driven couplings. A lot of work has been devoted to the calculation of magnetic couplings, for example, [1][2][3][4][5][6][7], where constructions with steel magnetic cores are considered. In [1,2], the influence of the permanent magnets geometry on the coupling characteristics is investigated.…”

In [3], the influence of the pole pairs number and the air gap size on the magnitude of the torque, developed by the coupling is considered.…”

Smooth Teeth: Why Multipoles Are Perfect Gears

“…Today, magnetic gears can compete with mechanical realizations in industrially relevant applications. Most of the designs are coaxial [7][8][9][10][11][12][13][14][15][16] and include intricate constructions like planetary [17] and cycloid gears [18]. Biaxial systems can also be found [19,20].…”
