Clutch

Definition: Mechanical device that connects and disconnects two rotating shafts, transmitting or interrupting motion and torque.

Definition: Mechanical element designed to stop, slow down, or hold a shaft using friction or mechanical resistance.

Definition: Safety mechanism that prevents damage to machinery by disengaging or slipping when transmitted torque exceeds a preset limit.

Principle: Acts using centrifugal force, generating resistance proportional to rotational speed.

Applications: Lifting systems, inertia-driven machinery.

Principle: Mechanical mechanism that engages when a predefined condition occurs, e.g., overspeed due to system failure.

Applications: Elevators, work platforms, lifting equipment — systems requiring fail-safe arrest.

Principle: Magnetic hysteresis or eddy currents generate a resisting torque without mechanical contact.

Applications: Test benches, tension control, precise load simulation.

Advantage: Contactless → long life and stable torque vs speed characteristics.
