A Description of Electromagnetic Clutches
INTRODUCTION
Electromagnetic clutches operate electrically, but transmit torque mechanically. This is why they used to be referred to as electromechanical clutches. 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 sixty years ago, the variety of applications and clutch designs has increased dramatically, but the basic operation remains the same.
Electromagnetic clutches seem simple, but complex variations fit them to multiple applications.People use electromagnetic (EM) clutches every day and often don’t realize it.
Anyone who switches on a lawn tractor, copy machine, or car air conditioner may be using an EM clutch are just as common.
Electromagnetic clutches operate electrically but transmit torque mechanically. Engineers once referred to them as electromechanical clutches. Over the years EM came to stand for electromagnetic, referring to the way the units actuate, but their basic operation has not changed.
Electromagnetic clutches come in many forms, including tooth, multiple disc, hysteresis, and magnetic particle. However, the most widely used version is the singleface design.
ABOUT ELECTROMAGNETIC CLUTCH
These electromagnetic clutches are designed to have a very high torque to size ratio. They include longlife friction materials, are corrosion protected and require little or no
maintenance after installation. Typical applications include copiers and printers, packaging and labelling machinery, medical equipment, conveyors, document feeders and textile machinery.
In a clutch when powers applied, a magnetic field is created in the coil . This field (flux) overcomes an
