With the boom in automation, their use has transformed, making them tools to manage rapid start-stop cycles in sectors such as packaging and textiles, where speed of reaction is still essential.
Today, thanks to power electronics, the VFD allows the management of speed, acceleration ramps of the engine and electric braking; Electromagnetic clutches and brakes are therefore less used than in the past, but continue to be used.
There are several standardised and “shelf-mounted” couplings on the market, which normally meet the simplest needs and are essentially oriented towards price containment
