The Importance of Inertia When Selecting a Clutch or Brake

From Ogura Industrial Corp.

A torque-limiting clutch may slip momentarily when machinery starts, but once it reaches steady-state speed, it holds tight. The reasons for the slippage may include a large acceleration rate and driven-component inertia. Acceleration is changeable with motor controls, but inertia is a physical property of the system and scales with

Electric Brake and Clutch Assemblies
Electric brake and clutch assemblies consist of elements for both the connection and disconnection of shafts (clutch) and for the slowing or stopping of shafts (brake) in equipment drives.
Torque Limiters and Slip Clutches
Torque limiters and slip clutches automatically slip or disengage the clutch at a predetermined torque.
Electric Brakes
Electric brakes are assemblies consisting of electrical elements for the slowing or stopping of shafts in equipment drives. Electrical power is required to activate the brake.
