Fabricante de frenos de partículas magnéticas & frenos de polvo magnético

XW Machinery is a magnetic powder brake manufacturer in China, supplying magnetic particle brake solutions for OEM machine builders, equipment manufacturers and industrial distributors. Our powder brake range includes solid-shaft and hollow-shaft designs, with standard torque ratings from 6–400 Nm for web handling and unwind tension control.

Unstable unwinding tension can cause film stretching, web breaks and inconsistent material feeding. Paired with a compatible current driver and tension controller, our brakes help regulate unwind resistance in slitting, printing, laminating, coating and packaging machines.

Powder Brakes for Industrial Web Tension Control

A powder brake uses magnetized particles to produce adjustable resistance on a rotating shaft. Changing the excitation current changes the braking torque, allowing the machine control system to match resistance to the process.

These brakes are used on unwind stations handling film, paper, foil, nonwoven and textile materials. For changing roll diameters, an automatic tension controller can adjust brake current using suitable tension feedback or roll-diameter compensation.

Find the Right Magnetic Particle Brake Design

Solid-Shaft Powder Brake: A configuration for machines using a shaft coupling or other suitable transmission connection. Confirm shaft dimensions and mounting requirements before selection.

Hollow-Shaft Magnetic Particle Brake: A through-shaft configuration for layouts that benefit from direct shaft mounting. Check bore size, keyway, mounting clearance and the method used to restrain the brake housing.

OEM Requirements: Send your machine drawing or existing brake specification so we can assess torque, installation dimensions, electrical compatibility and cooling requirements.

How Does a Magnetic Particle Brake Work?

DC current in the coil creates a magnetic field. Fine magnetic particles inside the brake align into chains, coupling the rotating member to the stationary member and resisting rotation. Increasing excitation current generally increases torque within the model’s operating range.

The brake provides controlled torque; a tension control system adjusts that torque as operating conditions change. During continuous slip, braking energy becomes heat, so cooling and thermal capacity must match the application.
