... causing the magnetic field in the coil's core to collapse quite suddenly. The collapse of the core's magnetic field induces a large voltage spike in the primary, which may be as high as 200 or 300 volts. The secondary winding of the coil consists of a very large number of turns of very fine magnet w ...

Their cycle requirements tend to be lower than industrial clutches, and their cost is more sensitive. Also, many mobile clutches are ...

Friction-plate electromagnetic couplings

Electromagnetic clutches and brakes operate electrically, but transmit torque mechanically. This is why they used to be referred to as electro-mechanical clutches or brakes. Over the years, EM became known as electromagnetic versus electro mechanical, referring more about their actuation method versus physical operation. Since the clutches started becoming popular over 60 years ago, the variety of applications and brake and clutch designs has increased dramatically, but the basic operation remains the same.This article is about the working principles of single face friction plate clutches and brakes. In this article, clutches and brakes are referred to as (mechanical) couplings.
