Categories Related to Electromagnetic Clutches
An electromagnetic clutch is a machine that uses electromagnetic force generated in a coil to connect two shafts and transmit power, or to disconnect two shafts and shut off power.
Since power transmission can be easily controlled by energizing the coil, not only can it be operated remotely, but it can also transmit power intermittently.
An electromagnetic clutch is classified into friction type, meshing type, pneumatic clutch type, and spring type, depending on the method of torque generation.
Of these, the friction type is the most commonly used because of its simple structure, low cost, and excellent controllability.
Electromagnetic clutches are used as machines that transmit the rotational power of engines, generators for automotive equipment, and driving power for hydraulic pumps.
Clutches can be mechanical, hydraulic, or electromagnetic, depending on their operating principle. However, electromagnetic clutches are commonly used in industrial applications. This is due to the fact that power transmission between shafts can be easily controlled by electromagnetic force.
In addition to automotive equipment, small electromagnetic clutches are used for torque transmission in office equipment and communication devices.
In addition to electromagnetic clutches, there are mechanical clutches and hydraulic clutches, depending on the actuation method.
Electromagnetic clutches are commonly used because they are easily controlled by electromagnetic force.
Electromagnetic clutches are classified into various types according to the torque generation method.
