Web tension control plays a crucial role in numerous industrial processes, especially in the realm of web handling and converting. The precise management of tension ensures the quality and consistency of the final product. In this context, magnetic particle brakes emerge as a sophisticated solution to optimize web tension control.
Magnetic particle brakes are based on electromagnetic principles and use magnetic powder to transmit torque. There is basically a linear relationship between the excitation current and the transmitted torque. Regardless of the slip, a certain amount of torque can be transmitted and the response speed is fast.
Magnetic particle brakes consists of two main components: the rotor and the stator. When a magnetic field is applied, the particles inside the brake engage, transmitting torque and allowing for controlled slippage. This inherent slip feature makes magnetic particle brakes an ideal choice for applications requiring precise tension control.
Magnetic particle brakes is an automatic control component with superior performance. It is widely used in various machinery for braking, loading and unwinding tension control in winding systems for different purposes.
