How Does a Hollow Shaft Magnetic Particle Brake Work?

The brake operates using electromagnetic particle transmission technology.

Working Principle

1. DC current energizes the electromagnetic coil.
2. Magnetic particles become magnetized inside the brake chamber.
3. Magnetic particle chains form between rotating components.
4. Adjustable braking torque is generated.
5. Torque output changes proportionally with excitation current.
6. Stable web tension is maintained throughout winding and unwinding operations.

Because braking torque remains independent of slip speed, the system provides exceptionally stable tension control for demanding industrial applications.
