Understanding friction - Habasit Expert Blog

The friction coefficient always depends on both friction partners (material composition, roughness of surface). Test: Rub various items with identical pressure, e.g. an eraser, a packet of cigarettes, a coin, a conveyor belt sample on various surfaces, e.g. on a table, a window, a piece of coarse fabric – the resistance will feel very different!

The application of linear induction motors to conveyors ...

Abstract: The principal advantage in using linear induction motors to drive conveyor belts is that force can be applied uniformly to the belt over a wide area without mechanical contact. The drive is therefore independent of the coefficient of friction between belt and rollers and belt stretch is less likely to occur. The main problem in designing a linear motor for such a drive arises from ...
