Question

What is the difference between electromagnetic clutch and electromagnetic brake?

Answer 1

Electromagnetic clutches operate electrically but transmit torque mechanically. This is why they used to be referred to as electro-mechanical clutches. Over the years, EMbecame 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 clutch designs has increased dramatically, but the basic operation remains the same today.
Electromagnetic brakes (also called electro-mechanical brakes or EM brakes) slow or stop motion using electromagnetic force to apply mechanical resistance (friction). The original name was "electro-mechanical brakes" but over the years the name changed to "electromagnetic brakes", referring to their actuation method. Since becoming popular in the mid-20th century especially in trains andtrams, the variety of applications and brakedesigns has increased dramatically, but the basic operation remains the same.

Both electromagnetic brakes and eddy current brakes use electromagnetic force but electromagnetic brakes ultimately depend on friction and eddy current brakes use magnetic force directly.

Answer 2

Answer:

Electromagnetic clutches and electromagnetic brakes are devices that control power and rotary movement using an electromagnetic force generated by energizing coils. Clutches connect and disconnect with power while brakes brake and maintain rotary movement. It is possible to divide these into electromagnetic actuated types and spring actuated types depending on that method of operation.
