Control Brake Tension in Industrial Applications

In even the most complex and critical applications, controlling coil current in brakes and clutches is essential to control brake tension. Accurate tension control improves product quality, reduces scrap, and ensures consistent performance. As a leading industrial clutch and brake control manufacturer, Regent Control provides advanced solutions designed for reliability, durability, and ease of integration.

How Magnetic Particle Brakes Maintain Tension

In a magnetic particle brake or clutch, torque is proportional to coil current. If coil current can be held constant, tension can be maintained in applications such as unwind stands, wire feed, and paper or film converting.

Ideal tension controls maintain coil current at a desired set point and compensate for changes in the brake coil’s resistance (caused by heating) and input supply voltage.

Control can be achieved in two ways:

• Closed-loop Systems: A sensor provides a feedback signal proportional to tension. A dancer arm is typical of tension sensors.
• Open-loop Systems: Control can be established using a roll diameter sensor. This is simple and effective for many applications.

Constant Current Tension Controls: Regent 8129

In either case, the goal is to maintain constant coil current in the magnetic particle brake or clutch. An example of one of our constant current (or torque) tension controls is Regent Controls’ 8129. Typical loads include magnetic particle and hysteresis brakes and clutches. Benefits include:

• Accepts 0-10 VDC or 4-20 mA control signals
• Independent adjustments for Gain and Offset
• Use in closed-loop or open-loop tension control systems
• Compact size, snaps onto DIN rail
• Maintains constant load current
• Can be used in open or closed loop tensioning systems

Benefits of Magnetic Particle Brakes

Magnetic particle brakes for tension control have advantages over other types of brakes, including low consumption of power, making them a cost-effective solution for many applications. Magnetic particle brakes for tension control also do not produce emissions or pollutants, making them a more environmentally friendly option than some other types of brakes. Other benefits include:

• Consistent, repeatable torque for accurate material handling
• Low heat generation
• Quiet operation suitable for industrial environments
• Long operational life with minimal disruption

Selecting the Right Tension Control Solution

Choosing the right system depends on the requirements of your process and equipment. Key considerations include:

• Load type (AC or DC) and voltage requirements
• Timing function (one-shot, interval, or continuous operation)
• Environmental factors (dust, moisture, vibration, temperature)
• Mounting style (DIN rail or panel)

One of our most popular models includes the >8129 Torque Control, along with brake and clutch power supplies, providing flexible options for different load types. Custom configurations can also be engineered for specialized tension control needs. Reach out today to discuss your requirements.
